OVERVIEW OF MONITORING PROGRAM

A watershed monitoring program has been in place on the Salmon-Challis National Forest since 1993, when 

103 permanent survey locations were established on the Salmon National Forest to monitor fine sediments 

and streambank stability in spawning habitat on streams throughout the Forest. Intermittent sampling also 

occurred in the mid-1980s. An additional 45 sites were established on the Challis National Forest in 1995. 

Additional sites have been established in subsequent years, and currently a total of 189 sites have been 

monitored on the Salmon-Challis National Forest. All sites are located in non-wilderness areas of the 

Salmon-Challis National Forest, and most are accessible by road or trail. Salmon-Challis National Forest 

personnel conduct monitoring of a subset of these sites each year. The monitoring sites sampled each year 

are selected based on project data needs.

Sampling Parameters

The following data are typically collected at each monitoring site:

Sediment sampling (Depth Fines): Depth fines are the portion of sediment from a core sample that is less 

than 0.25 inches in diameter. Depth fines data are collected in representative spawning habitat in a glide 

feature using the McNeil Core sampling methodology. The issue of sediment in Forest streams was one of 

the most often-cited concerns identified in public comment during the Salmon National Forest Land and 

Management Plan scoping process. Although relatively labor intensive, the McNeil core sampling 

methodology employed by the Forest to address these concerns is among the most objective, repeatable 

and biologically relevant of the various methods utilized to assess sediment levels and fish spawning 

habitat conditions of Forest streams. In light of the severely depressed numbers of returning spawners, 

substrate capability information derived from these surveys are perhaps the most relevant fish habitat 

information available to support land management decisions within critical habitat for listed anadromous 

stocks. Consultations with the National Marine Fisheries Service have additionally included identification of 

substrate sediment trends in Chinook salmon habitats as a principal term and condition of concurrence 

with Biological Assessments of Salmon Zone watersheds. 

Percent Bank Stability: Bank stability is measured along both banks over a 300-foot long reach upstream 

and/or downstream of the core sampling site. Bank instability can be initiated by natural events (floods, 

wildfires, mass wasting), wildlife or human disturbances (grazing, logging, roads) that change discharge, 

sediment load and channel stability (MacDonald et al., 1991). Bank material and vegetation type and 

density also affect the stability of banks (Platts, 1984). Removal of streambank/riparian vegetation along 

with mechanical bank damage reduces the structural stability of the streambank with several resultant 

negative impacts to fish productivity (Platts and Nelson, 1989). Eroding streambanks support little or no 

riparian vegetation, resulting in a loss of stream shading, undercut banks, and can cause stream widening 

and loss of aquatic habitat. Parameters for monitoring livestock grazing effects on aquatic habitat within 

the channel should include bank stability to evaluate bank erosion and sedimentation effects as well as 

changes in channel morphology that can reduce salmonid rearing space and cover. Bank stability is linked 

to cover factors that resist the forces of stream erosion. Cover may include vegetation, rocks, logs and 

other resistant materials. Stable and covered banks are in balance with water velocities, provide shade for 

temperature control, and supply terrestrial food needed to support salmonids.

AZAR: Aquatic Zone Analysis Rating (AZAR) is a numerical rating (0 to 100) based on qualitative ratings of a 

number of different factors related to overall stream health. These factors include vegetative stream 

cover, vegetative bank cover, dominant vegetative type, bank rock content, dominant bank rock size, bank 

cutting, instream sediment deposition, and ungulate bank damage. This provides a reconnaissance-level 

assessment of overall stream health.

Rosgen Channel Type: Rosgen channel types were originally collected on the majority of the established 

sites between 1995 and 2003. Channel type is based on a variety of parameters, including channel form, 

entrenchment ratio, width-to-depth ratio, gradient, sinuosity, and particle size. Channel type provides a 

way in which to compare conditions for different sampling sites on streams with similar characteristics. No

channel type data were collected between 2003 and 2015. 2015 monitoring once again included channel 

type determination for all sampled sites.

Site Descriptions (Notes and Photos): Site descriptions and photos of the core site and monitoring reach 

are typically collected during each sample but may be lacking for many sites. Field sketches have also been 

drawn for some sites. This is useful information as site conditions change, and documents slight year-toyear changes in the sampling site location because of changes in suitable sampling habitat.

Status of Dataset

Over 20 years of monitoring data are available, providing trend information at each monitoring site. This 

information is used extensively for environmental analysis, management plan development, site specific 

project planning, and disturbance monitoring. Some sample sites have extensive data, while others have 

relatively few data points. Each site was assigned to the following type, category, and status in order to 

categorize the dataset:

Code Category Definition

Type A Anadromous Stream segment accessible by salmon and steelhead

R Resident Non-anadromous fish-bearing stream segment

Category

F Full Record 15 or more samples, sampled most years

P Partial Record 8 to 14 samples

L Limited Record 3 to 7 samples

I Incomplete Record 0 to 2 samples

Status

C Current Valid sample site, sampled within last 5 years

L Lapsed Valid sample site, not sampled within last 5 years

D Discontinued Site no longer sampled

2015 MONITORING

A total of 60 sites were sampled between June and August 2015 by members of the SCNF Watershed 

Monitoring Crew and Student Conservation Association (SCA). Priorities for 2015 monitoring were focused 

on data collection for Range NEPA analysis and upcoming Forest Plan revision (currently scheduled to begin 

in 2017). Priority sites identified for sampling in 2015 included those that are within grazing allotments, but 

do not have continuous datasets or recent data. Six new sites were also established in 2015 and sampled 

in order to collect baseline data for streams that drain allotments or pastures where no monitoring sites 

currently exist.

MONITORING REPORT

This monitoring report was compiled in order to summarize the data for monitoring sites sampled in 2015 

(orange headings), and present the most recent data collected at all other monitoring sites that were not 

sampled in 2015 (blue headings).

Watershed characteristics were determined for each site using Streamstats batch processing of the 

sampling site point file (US Geological Survey, 2015). Watershed areas were delineated by Streamstats, 

and Streamstats provided the following basin data presented in this document:

 Drainage area

 Bankfull flow (estimated as the flow with a 1.5-year return interval)

 Mean annual flow

 Mean basin elevation

 Mean basin slope (calculated from 10-meter digital elevation model)

Basin characteristics were initially derived in September 2014 using Streamstats batch processing. These 

preliminary basin characteristics are in the 2014 Salmon-Challis National Forest Watershed Monitoring 

Report (USDA Forest Service, Salmon-Challis National Forest, 2014). Basin characteristics were reprocessed in Streamstats in December 2015 for 33 watersheds in which delineation errors existed from the 

initial processing, or in which GIS sampling point locations were corrected. One additional sample site 

watershed was corrected in February 2016.

GIS analysis was conducted using delineated watersheds for each sampling site and Salmon-Challis National 

Forest corporate GIS data. The following basin statistics were determined for each site:

 Fifth level watershed(s)

 Watershed aspect (N, NW, W, SW, S, SE, E, NE)

 Length of road in watershed (including open, closed, and unauthorized routes)

 Open road density (mi/sq mi)

 Percent of watershed in each landtype geology (Granitic, Volcanic, Sedimentary, Quartzite, Mixed, 

Alluvium)

 Percent of watershed by grazing allotment

 Percent of watershed by 2010-2014 wildfire (note: may add up to greater than 100% because of 

overlapping fires)

All of this information is used to analyze relationships between sample data, basin characteristics, and land 

use factors. Appendix A includes a compilation of watershed monitoring data, watershed basin 

characteristics, and data analysis. Note that for watersheds in which a portion of the watershed is outside 

of the Salmon-Challis National Forest boundary, the above analysis is for only the portion of the watershed 

that is within the SCNF boundary.

SAMPLING METHODS

Protocols for sampling depth fines and bank stability have been developed on the Salmon-Challis National 

Forest. These protocols were used to collect information in this report and are described below:

Sediment Sampling Protocol 

Long term monitoring field sites have been established throughout the Salmon-Challis National Forest. 

Driving and hiking directions to field sites are available. Once a field site is located, ideal spawning habitat 

is selected. Habitat sampling sites must meet specific depth, velocity, and predominant substrate particle 

size criteria. This is generally the glide section of the riffle- pool-glide pattern present in many streams. 

This habitat also contains medium sized, uniform substrate. Five core samples are excavated at each 

sampling site, working within an area generally encompassing that which would be utilized by the target 

species in redd construction activities. Patterning of cores within the sample site generally takes a diamond 

or oval form within the defined spawning area. 

At each sample site, a 12-inch coring tube is inserted into the streambed at the site to a sufficient depth to 

provide a seal from the surrounding water flow. Using a digging tool such as a small tire iron, the substrate 

area within the coring tube is disturbed to stir up any easily-suspended fine sediments and to loosen the 

substrate. 

Dependent upon target species, a 10 or 15 liter sample of substrate material is then excavated from within 

the coring tube into a bucket for transport to the shoreline processing area. A 15 liter sample approximates 

a six-inch deep excavation of the core tube to address substrate conditions at depths utilized by 

anadromous fish species. For assessment of spawning conditions for resident fish species, a 10 liter 

sample, representing a four inch pocket depth, is excavated from within the tube. This sample depth 

reflects the shallower egg pocket depths excavated by these smaller fish. Lines drawn on the inside of the 

sample collection buckets identify the needed sample volumes (4-inch depth/ 6-inch depth) for both 

resident and anadromous fish assessments. Lines drawn on these buckets represent half of the desired 

core volume so 2 buckets must be filled (to the line) for each core. Each sample site is designated as 

anadromous (A) or Resident (R), signifying the depth of core sample excavation.

Excavated core samples are transferred to an offstream area for screening through a series of stacked U.S. 

Standard sieves which segregate streambottom materials into nine specific size classes. Mesh sizes of 

these screens are identified below:
Salmon-Challis National Forest 2015 Watershed Monitoring Report February 2016

#20 0.0331 0.85

#70 0.0083 0.21

#270 or #300 0.0021 0.05

Collected substrate samples are graded through the screens by a process of repeated washing and shaking 

of the stacked sieves. Once sieving operations are completed, the contents of each individual screen are

measured volumetrically by water displacement, allowing determination of the fractional percentage of 

each size class comprising the total sample. Screen contents are carefully transferred to a receiving bucket 

filled just to the point of overflowing through a side mounted discharge spout. Water displaced by the 

screen contents is collected in graduated beakers, and water volume is recorded to the nearest 50 Ml. 

Receiving buckets and collecting beakers are reset to starting levels for each individual measurement.

Data are compiled on a data sheet in the field. The total volume of sediment retained by each sieve size is 

used to calculate the percent depth fines, or the percentage of sediment by volume that is less than 0.25 

inches diameter (ie, all material that is captured by the 1⁄4”, #4, #8, #20, #70, and #270/#300 sieves). The 

standard deviation of the 5 core samples at each sample site is also calculated.

Bank Stability Monitoring Protocol

Streambanks are considered stable if they do not show indications of any of the following features:

 Breakdown – Obvious blocks of bank broken away and lying adjacent to the bank. 

 Slumping or False Bank – Bank has obviously slipped down, cracks may or may not be obvious, but 

the slump feature is obvious.

 Fracture – A crack is visibly obvious on the bank indicating that the block of bank is about to slump 

or move into the stream.

 Vertical and Eroding – The bank is mostly unvegetated or uncovered as defined below and the bank 

angle is steeper than 80 degrees from the horizontal.

 Bank has bare soil with no rock, roots or vegetation to stabilize the bank and is susceptible to 

erosion at bankfull flows.

Streambanks are considered vegetated if they have the following features:

 Perennial vegetation ground cover is greater than 50%.

 Roots of vegetation cover more than 50% of the bank (deep rooted plants such as 

 Willow and sedges provide such cover).
Salmon-Challis National Forest 2015 Watershed Monitoring Report February 2016

11

Streambanks are considered “unvegetated stable” if they have the following features: 

 Banks are protected by rocks of cobble size or larger. Need to consider the stream power and 

evaluate if the rocks are large enough not to move during normal high flow events, on some 

streams boulder size rock may be needed for bank stability.

 Banks are protected by large woody debris such that they would not erode during high flow events.

Field Methodology

1) Select a representative stream reach. Avoid disturbances such as stock driveways that are an 

infrequent disturbance. However if livestock crossings are frequent and numerous these 

disturbances would be representative. Avoid fence boundaries where livestock impacts are 

concentrated. 

2) Evaluate the streambank located above and below the bankfull elevation. The figure below

describes where to take measurements when side channels or backwater areas are present along 

the stream reach. 

3) Walk both streambanks for 100 steps. At each step evaluate the streambank that is located along 

an imaginary line that is perpendicular to the tip of your foot. It is helpful to walk in the stream, if 

possible, when evaluating the banks. A step transect has been used instead of a measured transect 

because of the difficulty often encountered stringing a tape through thick brush. A step is defined 

as approximately 3 feet or one meter. Prior to beginning data collection the observer should lay 

out a tape for 100 feet and calibrate their step to achieve approximately 3 feet in each step.

4) Record each observation on the form in one of the four categories; vegetated stable, vegetated 

unstable, unvegetated stable or unvegetated unstable.

5) Sum each category for both the right and left bank.

6) Add up the vegetated stable and unvegetated stable totals for both banks and divide by 200 to get 

the Percent Stable Banks (assuming that 100 paces were recorded on each bank, if not divide by 

the total number of paces).

Equipment Necessary

1) Field form

2) Hip waders are needed on most streams for accessing both banks. On some streams the 

streambanks are best observed by wading down the stream. 

3) Counter (optional) to keep track of number of observations.

Additional considerations

While a streambank is normally easily defined the following situations can be observed in the field:

1) Multiple channels: 

When a side channel is present, determine whether the side channel leaves and re-enters the main 

channel within the reach.

If No, do not measure the bank in the side channel. Keep making your measurements on the bank of 

the main channel. Cross over the confluence of the side channel and take your next measurement on 

the bank of the main channel. Do not count paces within the bed of the side channel (Figure 1A).
Salmon-Challis National Forest 2015 Watershed Monitoring Report February 2016

12

If Yes, the observer needs to estimate the flow capacity of the side channel at bankfull stage and 

determine if it is equal to or greater than 50% of the flow of the main channel. If equal to or greater 

than 50%, then collect measurements on the outside bank of the side channel, rather than on the bank 

of the island associated with the main channel (figure 1B). If the side channel has a bankfull stage flow 

capacity less than 50% of the flow of the main channel, then take measurements on the bank of the 

island associated with the main channel. Do not count paces within the bed of the side channel (figure 

1A).

2) Backwater areas along a main channel:

When backwater or slough areas are located along a streambank, do not take bank measurements 

along the perimeter of the backwater. Cross over the backwater area and do not count paces within 

the bed of the backwater area. These areas are usually not susceptible to the erosive forces of bankfull 

flows and can be difficult to define bankfull features.

MIDDLE SALMON CHAMBERLAIN SUB-BASIN

Only the eastern portion of the 1,095,725-acre Middle Salmon Chamberlain Sub-Basin is located on lands 

administered by the Salmon-Challis National Forest. A total of 3 monitoring sites have been established 

and monitored in this sub-basin. Much of the sub-basin is in wilderness, but the monitoring sites are on 

non-wilderness or partial wilderness watersheds. Grazing does not occur in these areas. Only one 

monitoring site was sampled in this sub-basin in 2015.

REMARKS

The Corn Creek sample site is a relatively steep gradient channel with coarse substrate. Because of the 

gradient, this is primarily a transport reach, and fine substrate is not likely to accumulate. Although postfire runoff after the Mustang Complex fire (2012) likely resulted in excess sediment loads in Corn Creek in 

2012 and 2013, no increase in depth fines was detected through monitoring. No grazing occurs in the 

watershed with the exception of horse usage at the monitoring site. Steep channel gradient limits 

suitable sampling habitat and retention of fines, even if fines are routed through the system. Additional 

sampling should be limited, unless activity occurs within the watershed. However, it would be useful to 

collect channel type data. 

Sampling frequency – every 3 to 5 years.

2016 sampling priority – Low.

REMARKS

This site is difficult to access, the watershed is not grazed, and much of the watershed drains wilderness. 

Increased fines were not seen in 2013 following the 2012 Mustang Complex Fire. Bank stability has been 

high, and depth fines have been low. Additional sampling should occur, but infrequently.

Sampling frequency – every 3 to 5 years.

2016 sampling priority – Low.

REMARKS

The Horse Creek 2A site was affected by the Saddle Complex Fire (2011). Hillslopes in this area are 

primarily highly weathered granite, and this material has been highly mobile since the Saddle Fire. 

Although culverts on the Horse Creek Road were upsized in 2013, storm events continued to fill them 

with sand and small gravel-sized substrate. Sediment sampling in 2013 and 2014 indicated an increase in 

fines over baseline conditions, with 2015 showing a slight decrease. However, this channel also has 

naturally high fines because of the surrounding granitic geology. Additional sampling should be done 

until a baseline condition can be determined.

Sampling frequency – Every 2 years.

2016 sampling priority – Low.

Banks contain many downed trees and large areas of instability. However,

This site has the most complete dataset of all sites, with 22 out of 23 years sampled. Bank stability is 

consistently over 80% with the exception of the period from 1997 to 2001. Depth fines were consistently 

less than 30% with the exception of 1994. Additional data will be useful to continue to monitor impacts 

associated with grazing in the Indian Ridge allotment, mining activity, and numerous vegetation 

treatments currently occurring (prescribed fire and thinning). Because of the intensity of management in 

this watershed, frequent sampling should continue. 

Sampling frequency – 1 to 2 years.

REMARKS

This site has been sampled annually for the past 7 years. Trends indicate decreasing bank stability and 

increasing depth fines over the past several years. Some of this may be the result of post-fire flood 

events following the 2012 Mustang Complex Fire, but this is not entirely likely because of the low burn 

severity in this watershed. Additional monitoring should occur at this site to monitor impacts associated 

with grazing in the Indian Ridge allotment, and to determine if the trend of degrading conditions 

continues.

Sampling frequency – every 2 years.

REMARKS

This site was sampled continuously 1995 to 2002, then only once in the past 13 years. Bank stability is 

consistently greater than 80%, and depth fines are consistently less than 28%. No photos exist of this 

sampling site. No grazing occurs in the watershed. However, as this drainage is part of the Upper North 

Fork project, additional sampling should be conducted to gather baseline data that would be useful to 

monitor any impacts associated with vegetation treatments conducted over the next 10+ years. An 

assessment should also be made as to the suitability of this sampling site. Channel type data suggest a 

gradient of 11-12%, which is likely too steep for suitable spawning habitat.

Sampling frequency – every 2 to 3 years.

2016 sampling priority – High.

REMARKS

This site has been sampled almost continuously between 1993 and 2013. Bank stability has been 

generally greater than 90% (with one exception). Depth fines have been consistently less than 25% (with 

one exception in 2013). Grazing occurs in a small portion of the drainage. Additional sampling is needed 

to monitor any impacts associated with implementation of the Upper North Fork project, and to 

determine if the 2013 depth fines value represents an increasing trend.

Sampling frequency – every 2 to 3 years.

2016 sampling priority – High.

Sample Comments

Site has strong flow, deep pools. Strong flow has led to large substrate sizes. The 

large substrate size is most evident in the top shell of material which covers smaller 

substrate. Site was also slightly embedded. The reach has many recently downed 

trees, highly sinuous. Site has healthy vegetation leading to lots of downed trees and 

woody debris in the stream. 

REMARKS

This site has been sampled periodically in the past 10 years. Based on limited recent data, bank stability 

shows an improving trend, with recent samples greater than 90%. Depth fines have been consistently 

less than 28% (with the exception of 1996), and recently about 20%. Additional sampling is needed to 

monitor any impacts associated with implementation of the Upper North Fork Project. 

Sampling frequency – every 2 to 3 years.

2016 sampling priority – Moderate.

Sample Comments

The large size of the North Fork has led to larger substrate sizes and for 3A a 

lower percentage of depth fines. Steep areas next to the stream make up 

most of the erosional sections. Depth fines seem to be unaffected by these 

instabilities. Site has healthy vegetation.

REMARKS

This site has been sampled almost continuously, with the exception of 2006-2009. Bank stability has 

fluctuated from less than 50% to almost 100%, and a declining trend was seen from 2012 to 2014. Depth 

fines have been consistently less than 30%. Additional sampling is needed to monitor any impacts 

associated with implementation of the Upper North Fork project during the next 10+ years.

Sample Comments

For bank stability the creek split upstream and we took the left bank. There 

was a lot of deadfall and huge trees to crawl over while doing bank stability. 

Core sample was easy to dig.

REMARKS

This site has not been sampled since 2007. Bank stability has been mostly greater than 80%, with the 

most recent values near 100%. Depth fines have been consistently less than 22%. Additional sampling is 

needed to provide baseline data to monitor any impacts associated with implementation of the Upper 

North Fork Project over the next 10+ years, and to verify channel type information. The site location 

should be assessed to ensure that sediment deposition is not affected by the culvert.

Sampling frequency – every 2 to 3 years.

2016 sampling priority – High.

Sample Comments

Sediment and bank stability sampled in 2001, but bank stability was 

suspiciously low (63% stable). Only bank stability sampled in 2002, and 

results were in line with what would be expected (90.5%)

REMARKS

The bank stability reading in 2001 was suspiciously low, and AZAR descriptions did not validate the low 

number. Aside from this, little change has occurred at this site. Much of the watershed was burned 

during the 2000 Clear Creek Fire. No increase in fine sediment was detected in the 2001 sampling 

following the fire. The steep, confined channel gradient likely limits the retention of fine sediments, 

even if fine sediments are routed through the system. The site has not been sampled since 2001. 

Grazing occurs in only a small percentage of this drainage. Mine reclamation and development are 

occurring in this watershed. Additional sampling should occur only if mining activity increases in this 

watershed.

Sampling frequency – pending.

2016 sampling priority – Low.

REMARKS

This site has not been sampled since 2007. Grazing does not occur in the watershed, but mining 

reclamation and development are occurring. This site represents the best monitoring location for 

impacts related to mineral development at Blackbird Mine and Idaho Cobalt Mine. Additional data 

would be useful, particularly if additional mining activity was planned. Existing channel type data are 

incomplete and need to be verified.

Sampling frequency – every 3 to 5 years.

REMARKS

This site has not been monitored since 2007. The site is only a short distance upstream of Big Deer Creek 

2R, and this site is upstream of SF Big Deer Creek where the majority of mining impacts come into the 

system. Otherwise, conditions appear to be similar to those at the 2R site. This site does not need to be 

re-sampled, unless a comparison of conditions upstream and downstream of mining impacts is desired.

Sampling frequency – pending.

2016 sampling priority – Low.

Sample Comments

Field channel type was E4, but later discovered to be an error – probably G4c, but

should be confirmed. Percent fines was 51.1%, but math error was discovered –

actually 50.5%. Area is dominant with willows, creating strong baks. Slight damage to 

banks, mostly in crossing areas from cattle. No recent damage noticed.

REMARKS

This site has only been sampled once (1995). However, high fines were recorded during this sample. 

Additional sampling is needed to monitoring impacts associated with grazing in the Hat Creek allotment 

and determine if depth fines are still present at this site. Site conditions are unknown because of lack of 

data and photos, and it is unknown whether this represents a suitable sampling site. Channel type data 

are suspect and need to be re-collected.

Sampling frequency – every 2 to 3 years.

2016 sampling priority – Moderate (Information needed at this site, but higher priorities exist for 2016).

REMARKS

Clear Creek 1A experienced extreme sediment loads and channel shifting during post-fire flooding in 

2001 and 2002 (following the 2000 Clear Creek Fire). This site is located in a depositional area on the 

lower alluvial fan of Clear Creek. Sampling at this site was discontinued after 2003 because of channel 

shifting. Clear Creek 2A, located a short distance upstream, provides similar conditions and is now 

sampled instead of Clear Creek 1A.

REMARKS

This site is located on the alluvial fan of Clear Creek, a depositional area. High depth fines and low bank 

stability were recorded at this site in 2002 following post-fire flooding from the 2000 Clear Creek Fire. 

Depth fines returned to baseline conditions in the following years, but bank stability remained low 

because this is a new flood-formed channel. Additional sampling should occur at this site to monitor 

changes in channel stability and any impacts associated with grazing in the Clear Creek-Panther Creek 

allotment. Accurate channel type data would also be useful. 

Sampling frequency – every 2 to 3 years.

REMARKS

This site has not been sampled since 2005. At that time, the channel was impacted by post-fire flooding 

from the Clear Creek Fire. No grazing occurs in the watershed. Additional sampling is needed to 

determine if the channel has stabilized to baseline conditions and collect accurate channel type data.

Sampling frequency – 2016, then as needed.

2016 sampling priority – High.

REMARKS

This site has only been sampled once since 2005. Depth fines have been variable, with some values

greater than 30%. Additional sampling is needed to monitoring the impacts associated with grazing on 

the Williams Basin-Napias Creek Allotment, especially since many past values have been greater than 

30%. Channel type also needs to be verified (channel type data are lacking).

Sampling frequency – every 2 to 3 years.

REMARKS

This site has not been sampled since 2007. Bank stability has been generally greater than 80%, with the 

exception of 2000-2001. Depth fines have been consistently less than 29%. Grazing occurs in a small 

portion of the watershed. Musgrove Creek provides important salmon spawning habitat. Additional 

sampling is needed to continue monitoring any impacts associated with grazing in the Forney allotment 

and other impacts including roads. 

Sampling frequency – every 3 to 5 years.

2016 sampling priority – High.

Note that the Musgrove Creek culvert is scheduled for replacement, pending funding availability. The 

site should be assessed for potentially moving the sampling site upstream, outside of the influence of the 

culvert replacement project.

Sample Comments

Site has experienced extremely high flows this spring for extended periods of 

time. As a result Slightly unstable banks have been changed or torn off. 

Recreation and grazing also seem to have added to bank instability.

REMARKS

This site was sampled almost continuously between 1993 and 2011. Bank stability ranged from 30% to 

92%, with large year-to-year fluctuations. Depth fines ranged from 15% to 52%, generally greater than 

30%. Based on data collected, this site is impaired. Additional sampling is needed to continue monitoring 

any impacts associated with grazing in the Williams Basin-Napias Creek allotment, and to determine if 

conditions of low bank stability and high fines still exist since the last sample in 2011. Site conditions 

should be assessed to determine potential causes for variable bank stability and high fines.

Sampling frequency – every 1 to 2 years.

2016 sampling priority – High.

REMARKS

This site has not been sampled since 2005. Past sampling indicates bank stability on an improving trend, 

with more recent samples greater than 80%. Depth fines have been consistently between 20 and 30%, 

with a couple exceptions (possible sampling error or high water in 2005?). Additional sampling is needed 

to continue to monitor any impacts associated with grazing in the Williams Basin-Napias Creek allotment. 

However, continuous monitoring of 5 sites on Napias Creek is not needed. Recommendation is to stop 

monitoring the 2R site in favor of the 1R, 3R, and 5R sites. 

Sampling frequency – as needed.

2016 sampling priority – Low.

REMARKS

This site has been sampled almost continuously since 2000. This site is very close to Panther Creek 1A, 

with the difference being that it also includes the Clear Creek drainage. This site provided a good means 

to monitor impacts associated with the 2000 Clear Creek Fire, and it is likely that low bank stability 

measured between 2003 and 2008 was the result of blowouts in Clear Creek. The Clear Creek drainage 

has mostly recovered, and more recent bank stability values (since 2009) have been greater than 80%. 

Depth fines have been consistently less than 30%, with no large increases following the Clear Creek Fire. 

Additional periodic sampling at this site could be useful, and it would be helpful to collect missing 

channel type information, but the Panther Creek 1A site provides a better sampling site to monitor land 

use impacts in the Panther Creek drainage.

Sampling frequency – every 3 to 5 years.

2016 sampling priority – Low.

Site substrate is embedded with large rocks. Stream reach contains areas 

with thick shrubs as wells as coniferous forests. There may be slight grazing 

effects. Flow is often deep possibly leading to embededness. There is a 

variety of vegetation leading to adequate woody debris in the stream. 

REMARKS

This site was sampled continuously from 1995 to 2005, then periodically since 2005. Bank stability has 

been consistently greater than 80%, with one exception in 2013. Depth fines have been consistently less 

than 30%. Additional sampling is needed to monitor any impacts associated with grazing in the Morgan 

Creek allotment, and channel type information needs to be verified. 

Sampling frequency – every 2 to 3 years.

Sample Comments

Stream is surrounded by steep slopes. This glide location contained many 

large (>3”) rocks. There is heavy evidence of cattle grazing. Site is located in a 

predominantly coniferous forest unaffected by fire. Heavy flows in Panther 

Creek may contribute to the high amounts of large substrate. 

REMARKS

This site was sampled continuously from 1996 to 2002, then 2013-2014. Bank stability was less than 50% 

in 1999, but greater than 90% in recent years (despite evidence of heavy cattle grazing at the monitoring 

site in 2014). Depth fines were consistently less than 23%. Additional periodic sampling may be needed 

to monitor any impacts associated with the Morgan Creek allotment. However, this is also accomplished 

by the Panther Creek 4A site, with has a better dataset of baseline data. Therefore, this site is not a high 

priority for monitoring unless site specific impacts are occurring, and additional sampling at this site 

could occur every 3 to 5 years.

Sampling frequency – every 3 to 5 years.

2016 sampling priority – Low.

REMARKS

This site has only been sampled once since 2005. Bank stability has been highly variable, between 60% 

and 93%, and depth fines have varied between 12% and 36% - data indicate that this site has been 

impaired. Additional periodic sampling is needed at this site to monitor any impacts associated with 

grazing in the Williams Basin-Napias Creek allotment, and to assess any causes for low bank stability and 

high fines.

Sampling frequency – every 2 to 3 years.

2016 sampling priority – High.

Sample Comments

Bank stability and channel type data were not collected in 2015. The reach 

upstream of the core site goes onto private land, and a suitable reach does 

not exist on federal lands.

REMARKS

This site has only been sampled 5 times since 1993. Bank stability has been between 78% and 92%, and 

depth fines have been between 19% and 30%. Additional sampling is needed to monitor any impacts 

associated with grazing in the Morgan Creek allotment, and to collect channel type information. A 150-

acre private parcel exists southwest of the sampling site, but does not include SF Moyer Creek. The 

fence in question in 2015 is NOT a private property boundary, and the sample reach should extend 

upstream of the fence.

Sampling frequency – every 2 to 3 years.

2016 sampling priority – Moderate.

REMARKS

This site has not been sampled since 2005. Past data suggest generally high bank stability (near 100%, 

with one year exception), and low depth fines (less than 20%, with one year exception). Additional 

sampling is needed to monitor any impacts associated with grazing in the Clear Creek-Panther Creek

Sample Comments Channel is actively moving and downcutting; burn is evident on both sides of 

stream.

REMARKS

This watershed burned extensively in the 2012 Mustang Complex Fire. Intense rainfall in late June 2013 resulted in 

debris flows and flooding in Colson Creek. Conditions at this site were highly impacted by sediment deposition, 

followed by downcutting into the flood deposits during 2014 spring runoff. The relatively high gradient at this site 

makes it primarily a transport reach, and even one year after the flood event, depth fines were low. Decreased 

bank stability is a function of scoured banks, unconsolidated bank material deposited during flooding, and 

downcutting. 2015 sampling revealed a further decrease in bank stability. Soil condition in the upper watershed 

remains impacted (as of 2015). Additional sampling is needed to determine if baseline channel conditions are 

being reached. Sampling frequency – annually 2016-2017, then every 2 years. 2016 sampling priority – High. 

The 2014 GIS site location was inaccurate. Sample site GIS location, watershed, and basin data were corrected 

12/2015. This was a GIS error only - all samples were taken at the correct location.

Sample Comments Very silty, major fallen tree downstream of the site. Banks surrounding site 

are very sandy.

REMARKS

This site was re-sampled in 2014 after 8 years of no sampling. Grazing occurs in the watershed. The 

channel has a low gradient, granitic source, and a naturally sandy bed. Therefore fines are naturally high 

(40 to 75%), and the fine grained bank material is susceptible to bank erosion. 2014 sampling indicated a 

considerable decrease in bank stability, as well as slightly lower depth fines than previous samples. 

Additional monitoring should occur periodically at this site to monitor impacts associated with grazing in 

the Diamond Moose allotment. Current mining activity is occurring downstream of the monitoring site.

Sampling frequency – every 2 to 3 years.

2016 sampling priority – Moderate. Photos of this site are needed.

Sample Comments

Some undercuts go 2 feet in from bank; log weirs impact upstream end of 

reach; artificial banks beneath bridge in good shape; large part of “memorial” 

bank is unstable.

REMARKS

This site has been sampled continuously since 1993 with the exception of the period 2009 to 2012. 

Depth fines are generally less than 25% with the exception of 1997. Bank stability is generally greater 

than 80% with the exception of the period 1997 to 1999, and 2015. It appears that bank stability is 

highly influenced by artificial structures and human uses around the memorial. Some small scale postfire flood impacts have occurred in the Indian Creek watershed following the 2012 Mustang Complex 

Fire, but this did not result in increased fines. This may have affected bank stability in 2015. Additional 

monitoring should be conducted for at least 1 more year to monitor impacts associated with postMustang flooding, and to determine if bank stability continues to trend downward. 

It may be desirable to relocate the sample reach to an area with fewer artificial channel structures.

Sampling frequency – 2016, then every 2-3 years. 2016 sampling priority – High.

REMARKS

Indian Creek 2A has undergone a series of changes. The channel has jumped streambeds within the past 

2 year which has, in areas, left abandoned channels, formed new channels, uprooted trees and 

destabilized banks. The site was relocated a short distance upstream in 2014. A series of wash-outs 

after the Mustang fire has eroded hillsides and introduced sediment into the channel. However, depth 

fines have not shown an increase since the 2012 Mustang Fire, and bank stability remains high. 

Additional sampling is needed to monitor impacts associated with post-Mustang flood events.

Sampling frequency – Every 2 to 3 years.

2016 sampling priority – Low.

REMARKS

This site has been sampled during the last 3 years following the 2012 Mustang Complex Fire. Post-fire 

flood events in 2013 and 2014 resulted in high fines in 2013 and 2014, and decreased bank stability. The 

channel has been drastically influenced by these flood events. Depth fines are quickly flushed from the 

system in this reach (4% gradient, large stream, high energy), but bank stability will take longer to 

recover. Additional sampling is needed for 1 to 2 years to determine if baseline conditions are reached.

Sampling frequency – annually 2016-2017, then every 2-3 years.

2016 sampling priority – High.

Sample Comments

Previously sampled site at the mile 0.5 had undergone significant changes in size and substrate, 

making it unsuitable as a quantification site. New site chosen about 1/10 of a mile above old 

site. The coring site is not representative of the stream (about 1% looks this way), but it is by 

far the best looking SH spawning area in the lower mile of the stream. Overall the stream is a B3, but at the coring site it is a B-4. Site is a coarse gravel pool. Obviously site is different from 

the rest of the stream. The rest of the stream is mainly composed of larger cobbles.

REMARKS

This site was sampled only once, in 1993. Owl Creek 2A is not needed because Owl Creek 1A is sufficient 

to monitor conditions in the watershed.

AZAR Score 91 Rosgen Channel Type -

Sample Comments Site was sampled at high flows when depth fines may have been washed out 

of the sampling area. Very low depth fines were measured. 

REMARKS

This site drains an area highly affected by the 2012 Mustang Complex Fire, but no increase in fines was 

recorded in 2013 or 2014. The stream channel at this site is constricted by a steep slope on the right 

bank and the road embankment on the left bank. As such, it is characterized by coarse substrate and 

high energy, with limited sediment deposition. Suitable sampling habitat is limited.

High bank stability and low depth fines have been consistently recorded at this site since 1993. 

Additional sampling is not recommended in the short term because a more suitable sampling site for this 

watershed is available about 1.5 miles upstream (Spring Creek 2A).

Sampling frequency – as needed.

2016 sampling priority – Low.

Sample Comments

Some side channels (mid-channel bars & fallen debris); iron debris weirs; 

several cascade pools in upper reach; beyond flood plain there is a small side 

channel adjacent to a steep embankment w/ freshly exposed material

REMARKS

Spring Creek 2A has a limited dataset. However, this site provides a a more suitable sampling location 

than the Spring Creek 1A site for monitoring activities and disturbance in the Spring Creek Watershed. 

Because two monitoring sites are not needed in this area, future sampling should favor the Spring Creek 

2A site. Data from 2013 to 2015 show no apparent increase in depth fines as a result of the 2012 

Mustang Fire, although bank stability is on a decreasing trend. Major blowouts did not occur on Spring 

Creek. Additional sampling is recommended to determine whether a baseline condition is reached 

following recovery after the fire. 

Sampling frequency – annually 2016-2017, then every 2-3 years.

2016 Sampling priority – High.

REMARKS

This site was sampled continuously from 1993 to 2005, and 2013 to present. Bank stability has varied 

from 62% to 100%. The most recent value of 70% is likely the result of post-fire flooding and channel 

changes following the 2012 Mustang Fire. Depth fines have varied from 15% to 30%. Fines do not 

appear to have increased over baseline leves following the 2012 Mustang Fire. Additional sampling is 

needed to determine if baseline conditions (particularly bank stability) are reached following the 

Mustange Fire.

Sampling frequency – every 2 to 3 years.

2016 sampling priority – Low.

REMARKS

This site has not been sampled since 2005. Depth fines sampled between 1993 and 2005 were low –

between 8 and 22% - this is likely the result of the high energy in this channel (5% gradient). However, 

additional sampling is needed to monitor impacts associated with grazing in the Carmen Creek allotment.

REMARKS

This site has only been sampled once since 2003. Additional sampling is needed to monitor impacts 

associated with grazing in the Hat Creek and Deer-Iron Creek allotments. Past sampling has indicated 

periods of low bank stability, but generally low depth fines. Information about this site is lacking, and 

this site should be re-visited to verify site location, determine site suitability, and verify channel type. 

Photos of the site are needed.

Sampling frequency – every 2 to 3 years.

2016 sampling priority – High.

REMARKS

Sampling has shown bank stability consistently greater than 80%, with the exception of 2015, at 64.5%. 

Depth fines have been consistently less than 25%. Data show no apparent increases in fines as a result of 

the 2011 Salt Fire. The cause of the decrease in bank stability in 2015 is unknown. Additional periodic 

sampling is needed to determine impacts associated with grazing in the Deer-Iron Creek allotment, and 

to determine if the decreased bank stability in 2015 is a trend. 

Sampling frequency – every 2 to 3 years.

JESSE CREEK 1R Sample Year: 2010 REMARKS

This site has not been sampled since 2010. No grazing occurs in the watershed. This is the municipal 

watershed for the city of Salmon. The sampling site is located downstream of a subterranian section 

of channel (beneath talus), which may act to filter out sand-sized fines. As such, depth fines are 

consistently below 25% (with the exception of 1994). Additional sampling is needed to monitor 

impacts to the municipal watershed, determine site suitability, and verify channel type.

Sampling frequency – every 2 to 3 years.

2016 sampling priority – High.

It may be desirable to establish another monitoring site upstream of the subterranean section of 

channel (if a suitable site exists) to establish baseline data for monitoring impacts to the municipal 

watershed.

REMARKS

Limited data exist for this site. It may not be necessary to continue sampling 2 sites on Lake Creek, only 

1.1 miles apart. The Lake Creek 1R site is likely sufficient to monitor impacts in the watershed. 

However, as with the Lake Creek 1R site, this site shows high fines (30-51%). This site also showed low 

bank stability in the last year sampled (2009). Grazing occurs in the watershed. Additional sampling 

would be useful to monitor impacts associated with grazing in the Lake Creek Allotment and determine 

if conditions of high fines still exist. Channel type information is also needed at this site.

Sampling frequency – Consider discontinuing if Lake Creek 1R is sufficient, otherwise every 2 to 3 years.

2016 sampling priority – Moderate.

REMARKS

This site has not been sampled since 2005. Past data show bank stability consistently greater than 90% 

and depth fines less than 10% (2000 – 2005). Re-visiting this site and periodic sampling would be useful 

to monitor any impacts associated with grazing in the Williams Basin-Napias Basin allotment, and to 

verify channel type information. Sampling site suitability should also be assessed. Photos and extremely 

low fines suggest that this may not be suitable sampling habitat.

Sampling frequency – every 3 to 5 years.

2016 sampling priority – High.

Sample Comments

Moved site from old location due to beaver activity. Located near fisheries 

hobo site. New site appears to have a steeper gradient. Site is still high in 

vegetation but has larger rocks. 

REMARKS

This site was visited in 2015, but crew was unable to sample due to beaver dam at site and cattle grazing 

upstream that damaged stream bank providing no adequate sampling site. Beaver dams have inundated 

a 1⁄4-mile section of SF Iron Creek upstream of the confluence with WF Iron Creek. No alternative 

sampling sites were identified.

This site is discontinued until conditions change or another suitable site is located.

Sample Comments

Tight meanders and cutbanks on left bank near road (upstream of sample site) causes high 

near-bank-stress and threatens road. Log jam upstream of sample site caused cobble-pebble 

deposition and avulsion through right bank and onto right floodplain. Resulting distributaries 

w/ very low flow velocity and silty bedload flow into boggy flood plain lateral to right bank. 

Small-scale fine-grained 'deltas' at confluences of tributaries may lead to sand input. Large log 

jam ~300 feet upstream causes backing, deposition of fines and avulsion.

REMARKS

This site has been sampled continuously since 2008. Bank stability has been consistently greater than 

80%, and depth fines have varied between 17% and 29%. No increase in fines was measured 

following prescribed burning in the watershed in 2014. Additional sampling is needed to monitor 

impacts associated with grazing in the South Fork Williams Creek allotment.

Sampling frequency – every 2 to 3 years.

2016 sampling priority – Low.

REMARKS

This site has not been sampled since 2006. Bank stability has shown an improving trend, with the most 

recent values greater than 90%. Depth fines have shown an increasing trend, with a sharp increase in 

the most recent value (50.6% in 2006). The Wagonhammer Road is no longer suitable for vehicle travel, 

and access to the sampling site is now by foot (1.1 mile hike one-way). Additional sampling is needed at 

this site to monitor any impacts associated with grazing in the Burns Basin Allotment, to determine if the 

high fines measured in 2006 persist, and to update channel type information. Site suitability should also 

be assessed to ensure that the sampled site is representative of spawning habitat in the area (there is 

some indication that the site sampled in 2006 was over-widened).

Sampling frequency – every 2 to 3 years.

2016 sampling priority – High.

Sample Comments Digging was done downstream from original site. Rocks dug up were easy to 

break apart.

REMARKS

This site was sampled a number of years between 1993 and 2000, and again in 2010. Bank stability has 

ranged from 50% to 99%. Depth fines were consistently around 40%, increasing to 58% in 2010. 

Additional sampling is needed to monitor any impacts associated with grazing in the Grouse Creek and 

North Basin allotments. This is a very small stream at this location (2.7 square mile drainage area – one 

of the smallest). Site suitability should be assessed to ensure that the size of the stream can be sampled 

using this protocol. Very small streams tend to have high fines that are not representative of watershed 

conditions because of abundant organic debris. As such, re-sampling this site is not a high priority.

Sampling frequency – every 2 to 3 years.

2016 sampling priority – Low (higher priorities exist in 2016).

Site Name WF Iron Creek 1A Site Type Anadromous

Category Partial Status Current

Sub-Basin Middle Salmon-Panther Ranger District Salmon-Cobalt

Site Location

Site is located a short distance upstream of the confluence with SF Iron Creek. 

Access is via the South Fork Iron Creek Road (FR047), 0.3 miles from the Iron 

Creek Road (FR045). This is approx. 8.2 miles from Highway 93.

Site Comments

Site moved 500 ft upstream in 2015 because of beaver dams at established site 

- this site has generally poor spawning habitat- large boulders and cobbles.

Note: NHD stream name at this location is Iron Creek (not West Fork).

Sample Comments

Shallow stream with good worksite. Moderate flows. Lots of brush surrounding site. 

Banks had steep cuts. Lots of beaver activity both upstream and downstream from 

site may be contributing to high amounts of depth fines. Riparian vegetation 

surrounds immediate site but many other banks do not have appropriate vegetation 

and are eroding. There may also be impacts from cattle grazing.

REMARKS

This site was monitored continuously from 1995 to 2005, and 2012 to 2014. Bank stability was generally 

low in past samples (50 to 75%), but recent values have been greater than 80%. Depth fines have ranged 

from 20% to 49%, with the most recent value showing a sharp increase. Additional sampling is needed at 

this site to monitor any impacts associated with grazing in the Morgan Creek allotment and to determine 

if the high fines measured in 2014 persist.

Sampling frequency – every 2 to 3 years.

2016 sampling priority – Moderate.

Sample Comments Site had relatively low flow. Evidence of recent cattle grazing. Cattle grazing 

and lack of riparian vegetation may be contributing to bank instabilities. 

REMARKS

This site has been monitored nearly continuously since 1995. Bank stability has been generally greater 

than 80%, but the most recent value in 2014 showed a slight decrease to 75%. Depth fines have ranged 

from 17% to 61%, with many values exceeding 30%. Additional sampling is needed to monitor any 

impacts associated with grazing in the Morgan Creek allotment, particularly with depth fines recently 

exceeding 30%.

Sampling frequency – every 2 to 3 years.

2015 sampling priority – Moderate.

Sample Comments

High amounts of fines clogging sieves – resorted to sieving half a bucket at a time;

analysis conducted on reach upstream of core sample site; a collapsed bank/boulder 

serves to redirect the flow away from a portion of unstable bank upstream.

REMARKS

This site has been sampled almost continuously since 1995. Bank stability has ranged from 42% to 98%, 

on an increasing trend. Depth fines have been generally less than 30%, with exceptions in 1995-1996, 

and 2014-2015. A major blowout in a tributary 1 mile upstream of this site in 2014, following the 2013 

Lodgepole Fire, was responsible for greatly increased fines in 2014 and 2015. Additional annual sampling 

for at least 2 more years is needed until fines return to baseline conditions following the blowout.

Sampling frequency – annually 2016-2017, then every 2 years

2016 sampling priority – High.

This site was sampled nearly continuously from 1997-2004 and 2012-2015. Bank stability has ranged 

from 40% to 96%, with an increasing trend. Depth fines have ranged from 8% to 33%, with a decreasing

trend. Data do not appear to show a response to the 2013 Lodgepole Fire. Additional monitoring is 

needed to monitor any impacts associated with grazing in the Challis Creek allotment, as well as the 2013 

Lodgepole Fire.

REMARKS

This site was sampled nearly continuously from 2002 to 2010, and again in 2015. Bank stability has 

ranged from 73% to 99%, and depth fines have ranged from 11% to 30%. Additional sampling is needed 

to monitor any impacts associated with grazing in the Challis Creek allotment.

Sampling priority – every 2 to 3 years.

2016 sampling priority – Low.

The 2014 GIS sampling location was incorrect. Sample site GIS location, watershed, and basin data were 

corrected 12/2015. This was a GIS error only - all samples were taken at the correct location.

This location is 0.4 miles downstream of Challis Creek 4A – both sites are not needed, and the Challis 

Creek 3A site provides better sampling habitat.

REMARKS

This site was only sampled twice, in 2004 and 2005. Bank stability ranged from 74% to 100%, and depth 

fines ranged from 18% to 27%. The Challis Creek 4A site is only 0.4 miles upstream from the 3A site. 

Reconnaissance in 2015 indicated no reasonable sampling habitat at the 4A site because of abundant 

wood in the stream. Because of this, its close proximity to the 3A site (which contains a relatively long 

dataset), and the lack of baseline data, it was determined that the Challis Creek 4A site would be 

discontinued.

DISCONTINUED.

REMARKS

This site has a nearly continuous dataset since 1995. Bank stability has been consistently greater than 

90%. Depth Fines have ranged from 3% to 29%. Additional sampling is needed to monitor any impacts 

associated with grazing in the Garden Creek allotment.

Sampling frequency – every 2 to 3 years.

2016 sampling priority – Moderate (because of consistent low fines/high stability, other higher priority 

sites exist for 2016).

REMARKS

This site was established on August 19, 2015 in order to begin collecting baseline data to monitor any 

impacts associated with grazing in the Challis Creek and Garden Creek allotments, as well as hazardous

fuels treatments in the Big Hill project area. Additional sampling is needed to continue monitoring these 

potential impacts.

Sampling frequency – annually through 2017 to provide baseline data, then every 2 to 3 years.

2016 sampling priority – High.

REMARKS

This site was sampled continuously from 1995 to 2004 only. Bank stability ranged from 62% to 98%, with 

an increasing trend. Depth fines ranged from 14% to 22%, with a steady trend. This site was established 

to monitor any impacts just downstream of the landslide at the Grouse Creek mine. The Jordan Creek 

2A, 3A, and 4A sites are all very close together. Data from the 2A and 3A sites, located upstream and 

downstream of the landslide, did not show a lot of difference in fines or bank stability. The 3A site 

provides the best site to continue monitoring any impacts associated with mining and other uses in the 

upper watershed, and the 2A and 4A sites are discontinued.

REMARKS

This site was sampled nearly continuously from 1995 to 2004, and 2012 to 2015. Bank stability has been 

generally greater than 85%. Depth fines have ranged from 19% to 39%, with many values over 30%. 

Additional sampling is needed at this site to monitor any imacts associated with grazing in the Garden 

Creek allotment, particularly with fines often exceeding 30%. The Elevenmile Fire burned a large portion 

of this drainage in Aug-Sep 2015 (prior to the 2015 sampling, but before any runoff producing storm 

events). Several years of additional sampling is needed to monitor impacts from post-fire runoff and/or 

blowouts in this drainage.

Sampling frequency – every year (2016-2019), then every 2 to 3 years.

2016 sampling priority – High.

The 2014 GIS sampling location was slightly incorrect (400ft upstream of correct location). Sample site 

GIS location, watershed, and basin data were corrected 12/2015. This was a GIS error only - all samples 

were taken at the correct location.

REMARKS

This site has been sampled periodically since 2001. Bank stability has been consistently greater than 

90%. Depth fines have ranged from 8% to 42%, with the most recent value in 2015 at 41%. This is a very 

small, steep stream (drainage area is 1.5 square miles – the smallest of all sampling sites). Depth fines 

have increased steadily since the 2012 Halstead Fire (despite mostly low/moderate burn severity in the 

watershed), but it is unknown whether these are related. Additional sampling is needed to determine if 

this trend of increasing fines continues, and to determine what might be causing these fines. High fines 

in an ‘A’ type channel are rare, but this could be explained by the fact that this is a very small channel 

with abundant roughness and low flows. This site should be assessed to ensure that appropriate 

spawning habitat is being sampled, and that the site is large enough to sample using this protocol.

Sampling frequency – every 3 to 5 years.

2016 sampling priority – Low.

Sample Comments

Lots of woody debris down and throughout stream reach. Reach is mostly 

shaded. The dominant vegetation are conifers, with some shrubby material 

along the banks. Many pools. Log was down across the stream creating a 

small waterfall.

REMARKS

This site was monitored continuously from 1995 to 2004, then again in 2013. Bank stability has ranged 

from 69% to 96%, with an increasing trend. Depth fines have ranged from 29% to 45% - generally 

greater than 30%. The 2015 Elevenmile Fire burned a portion of this drainage, mostly at low and 

moderate severity. Additional sampling is needed to monitor any impacts associated with grazing in the 

Garden Creek allotment, to track changes resulting from post-fire runoff and/or blowouts, and to verify 

channel type.

Sampling frequency – annually 2016 through 2018, then every 2 to 3 years.

2016 sampling priority – High.

REMARKS

This site was sampled continuously from 1995 to 2004, then periodically since 2004. Bank stability has 

ranged from 72% to 100%, with an increasing trend. Depth fines have ranged from 10% to 30%, with 

recent values less than 30%. Monitoring indicated no impacts to the channel in 2013 or 2015 following 

the 2012 Halstead Fire. Other impacts in the watershed are limited (no grazing, few roads). Additional 

periodic sampling is needed to continue monitoring watershed condition.

Sampling frequency – every 3 to 5 years.

2016 sampling priority – Low.

Sample Comments

2015 sampling effort was misguided by GPS point above Eightmile Creek, 

found redd there, and moved site 0.7 miles upstream of Eightmile Creek 

confluence. Sample location should be downstream of Eightmile Creek.

REMARKS

This site was sampled continuously from 1995 to 2005, then periodically since 2005. Bank stability 

ranged from 54% to 90%, with an increasing trend. Depth fines ranged from 6% to 32%, with recent 

values between 20 and 22%. The 2015 Elevenmile Fire burned a large portion of the watershed – the 

2015 sampling occurred after the fire, but before any runoff-producing events. Additional sampling is 

needed to monitor any impacts associated with grazing in the Garden Creek allotment as well as 

increased sediment loads related to the Elevenmile Fire.

Sampling frequency – annually 2016-2018, then every 2 to 3 years.

2016 sampling priority – High.

Note: GIS location in 2014 was upstream of Eightmile Creek – this was incorrect. Site location and 

watershed were corrected 6/18/15, and basin data reflect corrected watershed delineation. 

**Be sure to follow the pre-2015 hand-drawn map and sample downstream of Eightmile Creek.

Sample Comments

Two fords crossing the stream; Conducted classification downstream of core 

site due to Mckay tributary entering just upstream of above core site; above 

tributary is a different type of reach than found at core site

REMARKS

This site was monitored continuously from 1995 to 2004, then periodically since 2004. Bank stability 

ranged from 60% to 96%, with an increasing trend. Depth fines ranged from 15% to 33%, with a 

decreasing trend in recent years. The 2015 Elevenmile Fire burned a large portion of the watershed (the 

2015 sampling occurred before the fire). Additional sampling is needed to monitor any impacts 

associated with grazing in the Garden Creek allotment as well as increased sediment loads related to the 

Elevenmile Fire.

Sampling frequency – annually 2016-2018, then every 2 to 3 years.

2016 sampling priority – High.

This site was sampled continuously from 1995 to 2007, and 2013 to 2015. Bank stability has been 

generally greater than 85% (with 1 year exception). Depth fines have varied from 11% to 33%. Samples 

following the 2012 Halstead Fire did not show an increase over baseline values for depth fines (despite 

multiple blowouts in the watershed), and bank stability did not decrease. Additional sampling is needed 

to monitor impacts associated with grazing in the Salmon River Breaks allotment, and to determine if a 

baseline condition for fines is reached following the Halstead Fire.

Sampling frequency – every 2 to 3 years.

Sample Comments

A cow trail runs along the stream on the right. Extensive ungulate damage on the right side 

about 30 yards up from the core site, (50-75% of the bank). Less damage through the rest of 

the reach on the right bank (0-25%). Left bank has less damage (25-50%). Most of this is in the 

first 30 yards, this is due to a steep slope that occurs after this. Dense vegetation and lots of 

woody debris towards the top of the reach. This seems to have come from the steep rocky 

slope. Almost entire bank (>90%) has experienced ungulate damage for ten yards below core. 

Substrate has lots of fines and was very easy to dig.

REMARKS

This site has been sampled only 3 times, beginning in 1994. Bank stability has been greater than 80%. 

Depth fines have ranged from 28% to 48%, with the most recent value showing an increase in fines. 

Additional sampling is needed at this site to monitor any impacts associated with grazing in the Squaw 

Creek allotment, to determine if the high fines measured in 2013 are persisting, to investigate the 

potential source of high fines (cattle impacts noted in 2013), and to collect channel type information.

Sampling frequency – every 2 to 3 years.

2016 sampling priority – High.

REMARKS

This site has been sampled nearly continuously since 1999. Bank stability has been consistently greater 

than 80%, with an increasing trend. Depth fines have ranged from 26% to 42%, with a slight decreasing 

trend. Fines showed an increase in 2013, following the 2012 Halstead Fire, followed by a decrease in 

subsequent years – however, these values were all similar to baseline values. The fire did not appear to 

have major impacts to channel conditions at this site. Additional sampling is needed to monitor any 

impacts associated with grazing in the Cape Horn allotment, as well as timber/veg treatments in the 

drainage.

Sampling frequency – every 2 to 3 years. 2016 sampling priority – Low.

The 2014 GIS sampling location was incorrect. Sample site GIS location, watershed, and basin data were 

corrected 12/2015. This was a GIS error only - all samples were taken at the correct location.

Sample Comments

Digging was surprisingly easy. A lot less fines than expected considering all the 

beaver activity. Beaver activity from mouth to almost half a mile up the 

stream channel. Very unstable banks because of this. Bank stability not 

measured.

REMARKS

This site was sampled continuously from 1995 to 2002, then again in 2010. Bank stability has been 

generally greater than 80%. Percent fines has ranged from 10% to 42% - most values were greater than 

30%, but the most recent value in 2010 was considerably lower at 10%. Additional sampling is needed to 

monitor any potential impacts associated with grazing in the Herd Creek and East Pass Creek allotments. 

Site suitability needs to be assessed because of potential beaver dams (see 2010 notes).

Sampling priority – every 2 to 3 years.

2016 sampling priority – High.

Sample Comments Noticeably high levels of fines due to old beaver dam below site (now a few

REMARKS

This site has only been sampled 4 times, beginning in 2003. Bank stability has been consistently greater 

than 90%. Depth fines have ranged from 18% to 33%. Although this site is in close proximity to Herd 

Creek 1A, its drainage basin does not include East Pass Creek, and data from this site provides 

information about impacts in the Herd Creek drainage alone. Additional sampling is needed to monitor 

any impacts associated with grazing in the East Pass Creek and Herd Creek allotments.

Sampling frequency – every 2 to 3 years.

2016 sampling priority – High.

The 2014 GIS watershed delineation was incorrect (but sample site GIS location was correct). Watershed 

and basin data were corrected 12/2015.

Left bank had a rock outcrop with shrubs in front of fire weed/rush. Bank right 

sage brush, rocky, sandy material, forbes, (rush) fireweed. At 6 yards on right 

bank, bank is undercut. On left bank at 11 yards Drainage steep with woody 

debris. Signs of bank sloughs and ungulate access. 

REMARKS

This site was sampled continuously from 1995 to 1999, then again in 2013. Bank stability has ranged 

from 70% to 96%, with an increasing trend. Depth fines have been consistently between 17% and 28%. 

Additional sampling is needed to monitor any impacts associated with grazing in the Herd Creek 

allotment. However, because access is difficult and conditions in this watershed are also reflected in the 

Herd Creek 2A site, sampling can occur more infrequently.

Sampling frequency – every 3 to 5 years.

2016 sampling priority – Moderate.

Drainage basin was originally delineated in 2014 including EF Herd Creek (incorrect). The site location 

and watershed were corrected 6/18/15, and basin data reflect the correct watershed.

LOWER MIDDLE FORK SALMON SUB-BASIN

Slightly more than half of the 880,270 -acre Lower Middle Fork Salmon River sub-basin consists of lands 

administered by the Salmon-Challis National Forest. A total of 10 monitoring sites have been established 

and monitored in this sub-basin. 1 of these sites has been discontinued. Much of the Forest Service lands 

within this sub-basin are part of the Frank Church River of No Return Wilderness. Grazing occurs in the 

non-wilderness portions of the sub-basin, and the impacts of grazing are monitored at these sites. A total 

of 2 sites were monitored in 2015 in this sub-basin. This sub-basin includes the following areas:

 Camas Creek Watershed

 Yellowjacket Creek Watershed

Sample Comments

Bank stability reach conducted downstream of core site along wide meander. 

In contrast to stable left bank, right bank is composed almost entirely of 

unstable cut bank.

REMARKS

This site was sampled continuously from 1993 to 2005, then periodically since 2005. Bank stability has 

ranged from 41% to 100%, with the most recent sample at 53%. Because of large size of channel, reach

selection may have a large influence on bank stability result – this may account for the wide fluctuations. 

Depth fines have ranged from 18% to 32%. Additional sampling is needed to monitor any impacts 

associated with grazing in the Camas Creek allotment.

Sampling frequency – 2 to 3 years. 

2016 sampling priority – Low.

The 2014 GIS sampling location was slightly incorrect (only 400 ft off). Sample site GIS location, 

watershed, and basin data were corrected 12/2015. This was a GIS error only - all samples were taken at 

the correct location.

Moderate vegetation and large point bars. Camas Creek is wide here. 

Substrate is skewed toward larger sizes (especially 1” material). Excellent 

point bar to use as a work space. Some instabilities along reach and near core 

site. Horse use is common here. 

REMARKS

This site was sampled continuously from 1993 to 2004, then periodically after 2004. Bank stability 

ranged from 33% to 92%, with an increasing trend. Because of large size of channel, reach selection may 

have a large influence on bank stability result – this may account for the wide fluctuations. Depth fines 

ranged from 12% to 33%. Additional sampling is needed to monitor any impacts associated with grazing 

in the Camas Creek allotment.

Sample Comments

Stream has healthy vegetation and average sized point bars. Road comes 

close to stream. Moderate flows experienced during sampling. Point bar 

creates good work space. 1” substrate was most common. 

REMARKS

This site has been sampled nearly continuously since 1993. Bank stability has ranged from 39% to 98%, 

with an increasing trend. Depth fines have ranged from 8% to 40%, with many values exceeding 30%. 

Additional sampling is needed to monitor any impacts associated with grazing in the Camas Creek and 

Morgan Creek allotments.

Sampling frequency – every 2 years.

2016 sampling priority – Low.

Pre-2000 samples were taken at a site about 0.6 miles upstream of present site, although site location is 

not always recorded for older samples. The 2014 GIS sampling location was incorrect (at pre-2000 site 

location). Sample site GIS location, watershed, and basin data were corrected 2/2016.

Sample Comments

Stream is small in size. Lots of shrubs. A high amount of fines was found 

here. Cores were sieved and measured in multiple portions because of excess 

fines. Stream has low gradient around core site. 

REMARKS

This site was sampled continuously from 2000 to 2004, then periodically since 2004. Bank stability has 

been consistently greater than 80%. Depth fines have ranged from 28% to 50%, mostly greater than 

30%. Additional sampling is needed to monitor any impacts associated with grazing in the Camas Creek 

and Morgan Creek allotments, to determine if the high fines measured in 2014 represents a trend (and 

any apparent cause of the high fines), and to collect channel type information.

Sampling frequency – every 2 to 3 years.

2016 sampling priority – Moderate.

REMARKS

This site has only been sampled 3 times, beginning in 1993. Bank stability has been high (greater than 

90%), and depth fines have ranged from 18% to 23%. No grazing occurs in this watershed. Additional 

sampling is needed to monitor watershed condition and extend the baseline dataset (no sampling has 

been done here in 13 years), and to collect channel type information.

Sampling frequency – every 3 to 5 years.

2016 sampling priority – Moderate (although additional data are needed at this site, other higher priority 

sites exist for 2016 in grazing allotment sites.)

REMARKS

This site has only been sampled 3 times, between 1993 and 1996. Bank stability was very high, and 

depth fines ranged from 22% to 30%. The Yellowjacket 1A and 2A sites are not both needed to monitor 

impacts in the watershed. Because baseline data for the 1A site is limited, this site should be 

discontinued in favor of the 2A site. However, an assessment should be made in the field as to which 

site represents better sampling habitat.

UPPER MIDDLE FORK SALMON SUB-BASIN

The majority of the 960,920 -acre Upper Middle Fork Salmon River sub-basin consists of lands administered 

by the Salmon-Challis National Forest. Only 2 monitoring sites have been established and monitored in this 

sub-basin. No sites have been discontinued in this sub-basin. Much of the Forest Service lands within this 

sub-basin are part of the Frank Church River of No Return Wilderness. Grazing occurs in the non-wilderness 

portions of the sub-basin, and the impacts of grazing are monitored at these sites. No sites were 

monitored in 2015 in this sub-basin. The two sites in this sub-basin are in the Beaver Creek/Marsh Creek 

area.

Sample Comments

Stream is located in a marsh/meadow. Wide stream with high sinuousity. 

Chinook salmon observed during sampling. Average distribution of substrate 

observed. 

REMARKS

This site has been sampled 5 times, beginning in 2009. Bank stability has been high, consistently greater 

than 85%. Depth fines have ranged from 16% to 34%. Channel conditions do not appear to have been 

affected by post-fire runoff and sedimentation following the 2012 Halstead Fire, although depth fines did 

increase slightly in 2014. This site has a very low gradient, favoring deposition of fine material. 

Additional sampling is needed to monitor impacts associated with grazing in the Cape Horn allotment, 

and to collect channel type information. 

Sampling frequency – every 2 to 3 years.

2016 sampling priority – Moderate.

REMARKS

This site has been sampled 7 times, beginning in 2007. Bank stability has been high, consistently greater 

than 85%. Depth fines have been generally between 20% and 30%, with one exception at 40% in 2013. 

The increase in fines seen in 2013 may be the result of post-fire runoff and sedimentation from the 2012 

Halstead Fire, but conditions returned to baseline in 2014. Additional sampling is needed to monitor 

impacts associated with grazing in the Cape Horn allotment, and to collect channel type information. 

Sampling frequency – every 2 to 3 years.

Sample Comments

Stream is surrounded by cliffs. Ungulate damage near core site, but less in reach, 

mostly in vegetated areas, so still fairly stable. Surrounding area is sage brush hills. 

Gradient increases near the top of the reach. Left bank about 50’ up from reach 

contains very large rocks held in place by vegetation. Not many grasses or forbes, 

predominately shrubs, trees, rocks.

REMARKS

This site has been sampled periodically since 1993. Bank stability has been generally high, and depth fines have 

been low. This is not an ideal site because it is affected by impacts occurring on BLM land. Need to explore 

alternative options for sampling in this pasture, possibly further upstream in the basin. Site was visited in 2015 but 

the crew was unable to reach the FS boundary, starting from the existing site. Additional sampling is on hold until 

additional reconnaissance can be completed.

Sampling frequency – On hold. 2016 sampling priority – Low.

GIS point was previously located at FS Boundary – this was incorrect. Sampling has always been done at the 

location downstream of the FS boundary, and reconnaissance indicates that no suitable sampling site exists at the 

FS boundary. GIS point corrected 6/18/2015, and basin data reflects the corrected watershed. 

Note that length of road, geology, and grazing alotments only consider FS lands.

Sample Comments

Banks are borderline stable/unstable. Lots of vegetation holding sediment in 

place with small undercuts. Bank angle leads ro unstable rocks and sediment, 

but not terribly unstable.

REMARKS

This site was sampled continuously from 2001 to 2009, and periodically since 2009. Bank stability showed a sharp 

decrease in 2015 to 52%. Depth fines have been consistently between 10% and 22% (low). This site is 1 mile 

downstream of the FS boundary. Alternate suitable sampling sites at or upstream of the FS boundary need to be 

assessed. Data collected at this site may be measuring impacts occurring on BLM lands. Additional sampling is 

needed to monitor any impacts associated with grazing on the Pattee Creek and Agency Creek allotments, but site 

reconnaissance should occur first.

Sampling frequency – every 2 to 3 years. 2016 sampling priority – Low.

The 2014 GIS sampling location was incorrect. Sample site GIS location, watershed, and basin data were corrected 

12/2015. This was a GIS error only - all samples were taken at the correct location.

REMARKS

4 sampling sites were established on Bear Valley Creek in 1993, and they are situated very close to each 

other. Continuous sampling of all 4 sites is not needed to monitor conditions in the watershed. The 3A 

site has only 5 years of data (1993-2000), and is discontinued. The 1A site provides a good monitoring 

site for this area with sufficient baseline data.

Site revisited in 9/9/2003 – bank stability measured only – 64% stable/36% 

unstable. Bank stability was marginal because of shallow rooted vegetation, 

and lots of bank rolling that could shear with bank trampling.

REMARKS

This site was sampled continuously from 1997 to 2005, but only once since 2005. Bank stability has been 

generally very high. Depth fines have been consistently high – between 32% and 52%. The cause of the 

high fines is unknown, although the very low gradient may play a role. Additional sampling is needed to 

monitor any impacts associated with grazing in the Upper Hayden allotment, to update channel type 

information, and to assess the source/cause of high fines.

Sampling frequency – every 2 to 3 years.

2016 sampling priority – High.

riffle had much shallower mean and bankfull width, which may have resulted in an Atype stream classification if stream widening did not exist.

REMARKS

This site has been sampled EVERY YEAR between 1993 and 2014. While it is a good training site, 

additional sampling is not needed on an annual basis to monitor watershed impacts. Bank stability has 

been very high, and depth fines have shown a decreasing trend, but with some recent values still greater 

than 30%. Additional sampling is needed to monitor impacts associated with grazing in the Hawley Creek 

allotment and to assess whether the trend of decreasing fines continues.

Sampling frequency – every 2 to 3 years.

2016 sampling priority – Moderate.

REMARKS

This site was sampled continuously from 1993 to 2004, then periodically since 2004. Bank stability has 

been high, particularly in recent years. Depth fines have shown a considerable increase in the last two 

years sampled (2013-2014) over previous levels, which were low. 40% fines are not typical in a large ‘B’ 

channel such as this. Additional sampling is needed to monitor any impacts associated with grazing in 

the Lee Creek and Upper Timber Creek allotments, to determine if the trend of increasing fines is 

continuing, and to assess the cause/source of high fines.

Sampling frequency – every 2 to 3 years.

2016 sampling priority – Moderate.

Comments

Very steep riffle on north fork Big Creek just above confluence (evidence of entrenchment below 

confluence). Mid-channel bar bifurcates flow at this steep riffle. Gradient measured @ middle of 

steep mid-channel bar instead of confluence to prevent a likely over-steeping artifact. NF site 

appears to be a C in the confluence zone because floodprone width encompases floodprone 

width of SF site. Stream is likely a B-type upstream of core site.

Channel type previously recorded as C3 (1998).

REMARKS

This site was sampled continuously from 1995 to 2005, then again in 2012-2013. Bank stability in the 

past was very low, ranging from 13% to 60%, but recent years have shown improvement to values 

greater than 80%. Depth fines have been fairly consistent over the years, with recent values between 20 

and 30%. Additional sampling is needed to monitor any impacts associated with grazing in the 

Wildhorse, North Fork, and Park Creek allotments.

Sampling frequency – every 2 to 3 years.

2016 sampling priority – Moderate (NF Big Lost 2R is higher priority in 2016).

REMARKS

This site was sampled continuously from 1995 to 2004, then twice since then. Bank stability has shown an 

increasing trend, with recent values very high. Depth fines have shown a slight increasing trend, with recent values 

around 30%. Additional sampling is needed to monitor any impacts associated with grazing in the Boone Creek 

allotment, and to determine if the trend of increasing fines continues. The site location should be assessed to 

better determine if past samples were done on EF Big Lost River or Star Hope Creek.

Sampling frequency – every 2 to 3 years.

2016 sampling priority – High.

GIS point was located downstream of EF Big Lost River (on EF Big Lost), and watershed included EF Big Lost River. 

Assumption is that this is incorrect – relocated GIS point to Star Hope Creek just upstream of confluence with EF Big 

Lost and delineated new watershed on 6/18/15. Basin data reflect corrected watershed delineation. There is some 

question whether this site was sampled on the EF Big Lost downstream of the confluence (and named incorrectly as 

Star Hope) or on Star Hope upstream of the confluence. If it is upstream of the confluence, then it is redundant 

with Star Hope 1R.

Sample Comments Not much pooling at site. There are a lot of large rocks. Does not look 

suitable for resident fish spawning.

REMARKS

This site was sampled continuously from 1995 to 2007, and not since then. Bank stability showed an 

increasing trend, with the most recent samples being very high. Depth fines showed a decreasing trend, 

with the most recent samples being low. Additional sampling is needed to monitor any impacts 

associated with grazing in the Copper Basin and Boone Creek allotments. 2007 observations indicate 

that the site is marginal for spawning habitat – alternate locations for sampling should be assessed. 

Sampling frequency – Consider discontinuing this site and only sampling the Star Hope 0R site a short 

distance downstream, otherwise every 2 to 3 years.

2016 sampling priority – Low (sampling of Star Hope 0R and reconnaissance will occur in 2016).

REMARKS

This site has been sampled nearly continuously since 1995. Bank stability has shown an increasing trend, 

with recent values very high. Depth fines have been more or less steady, with recent values around 30%. 

Grazing occurs in only a small portion of the watershed. Additional sampling is needed to continue to 

monitor channel conditions and any impacts from grazing in the Wildhorse allotment, and to collect 

missing channel type information. 

Sampling frequency – every 2 to 3 years.

2016 sampling priority – High.

REMARKS

This site was sampled continuously from 1995 to 2004, then from 2011 to 2014. Bank stability has 

ranged from 0% to 100% - highly variable. Depth fines have been very consistently in the 20 to 30% 

range. Additional sampling is needed to monitor any impacts associated with grazing in the Antelope, 

Leadbelt, and Hurst Canyon allotments, and to further define the bank stability trend.

Sampling frequency – every 1 to 2 years.

2016 sampling priority – Moderate (Antelope Creek 2R and 3R are higher priorities in 2016).

Sample Comments

This site has not been surveyed the last few years because of beaver activity. The 

beaver dams blew out this past spring, as a result, bank stability readings are very 

low.

REMARKS

This site was sampled twice, beginning in 2007. Bank stability was relatively low (65-70%), and depth 

fines were between 25% and 30%. This sampling site was abandoned because of extensive beaver 

activity, and a new site was established upstream (Bear Creek 2R) to monitor impacts in the watershed.

This is the new Bear Creek site established in 2010, replacing Bear Creek 1R, 

which is impacted by beaver dams. 2010 notes indicate that this site has similar 

stream characteristics and bank vegetation as the 1R site, just no beaver dams.

REMARKS

This site was sampled 4 times, beginning in 2010. Bank stability ranged from 28% to 90%, and depth 

fines ranged from 22% to 44%. Depth fines have increased over the past few years to high fines. 

Additional sampling is needed to monitor any impacts associated with grazing in the Antelope allotment, 

determine if the trend of increasing fines is continuing, and collect channel type information.

Sampling frequency – every 2 years.

REMARKS

This site has been sampled nearly continuously since 1995. Bank stability has shown an increasing trend 

to recently high values. Depth fines have been consistently high, with recent values around 50%. The 

site appears to be heavily impacted by cattle, with abundant silt in the pools. Additional sampling is 

needed to monitor channel condition and any impacts associated with grazing in the Cherry Creek 

allotment. The site should be assessed on a reach scale to help determine the source of the fines (ie, 

does it occur throughout the reach, or is it localized at the sampling site? Is trampling leading to channel 

widening and siltation? Any other factors related to silt deposition?)

Sampling frequency – every 1 to 2 years.

2016 sampling priority – High.

Sample Comments

Glide is deep but able to be sampled. Crew encountered a fisherman who was 

pleased to see us and commended the USFS for good management and the health 

improvement in this river he's witnessed in the last 20 years. "No more cows 

trampling the river." Numerous well-developed point bars (lightly vegetated); Right 

bank had exposed vertical cut banks (heavily vegetated and hard to access).

REMARKS

This site has been sampled continuously since 2001. Bank stability has varied, with recent values greater 

than 80%. Depth fines have recently been between 20 and 30%. Additional sampling is needed to 

monitor any impacts associated with grazing in the Mill Creek allotment. 

Sampling frequency – every 2 to 3 years.

2016 sampling priority – Low.

The 2014 GIS sampling location was incorrect (900 ft off). Sample site GIS location, watershed, and basin 

data were corrected 12/2015. This was a GIS error only - all samples were taken at the correct location.

reach a braided system upstream of core site; all mid-channel bars/islands are 

densely vegetated; sinuosity only measured upstream from core site to short 

braided section, approximately 135 feet.

REMARKS

This site has been sampled nearly continuously since 1996. Bank stability has shown an increasing trend, 

with recent values greater than 80%. Depth fines have been consistenly around 30%, with some values 

greater than 30%. Additional sampling is needed to monitor any impacts associated with grazing in the

Sample Comments

Cobbles diminished by ~30% between 2014 and 1015. On Rosgen section: Relatively 

high sinuosity caused by channel migration around downed trees and log jams; 

backwater pools and fine sediment deposition upstream of log jams; wide floodplain 

w/ boggy standing water in places; old pleistocene terrace constrains floodplain. 

Noticed only very minor ungulate damage; deposits of fines were occuring in side 

pools.

REMARKS

This site has been monitored nearly continuously since 2001. Bank stability has been variable, with 2015 

showin a sharp decrease. Depth fines have been consistently less than 30%. Additional sampling is 

needed to monitor any impacts associated with grazing in the Mill Creek allotment.

Sample Comments

Old core site was immediately upstream of wood debris pour feature (railroad tie in 

creek). Due to fine sediment buildup, site was moved 34 yeards upstream of ford. 

Fallen woody debris. Dense, fallen vegetation throughout channel made walking the 

entire reach impossible. Massive amounts of veg holding banks solidly. Easier to 

cross at ford and walk to site along left bank (pin on LB).

REMARKS

This site has been sampled periodically since 1995. Bank stability has been consistently high. Depth 

fines have shown a steady increasing trend, with recent values around 30%. Additional sampling is 

needed to monitor any impacts associated with grazing in the Horse Creek allotment. Alternate suitable 

sampling locations within the FS boundary should be assessed.

REMARKS

This site has been monitored semi-continuously since 2000. Bank stability has been high. Depth fines 

have shown an increasing trend over the last 5 years, with the most recent value greater than 40%. 

Additional sampling is needed to monitor impacts associated with grazing in the Pass Creek allotment 

and to determine if the trend of increasing fines continues.

Sampling frequency – every 1 to 2 years.

2016 sampling priority – Moderate (This would be high priority, but because of limited personnel/time, 

2016 sampling will focus on Big Lost River sites that have been sampled less recently).

SYNTHESIS

Only an initial synthesis of data is included in this monitoring repert. Additional analysis will be provided in 

the 2016 monitoring report, after additional data is collected in 2016 to fill in key data gaps. Preliminary 

dataset analysis in 2014 indicated that channel type has the strongest correlation with depth fines, 

although this relationship will be re-analyzed in the 2016 monitoring report after more channel types are 

updated. 

Status of Dataset

The following table summarizes the status of the Watershed Monitoring dataset. The goal is for all 172 

non-discontinued sites to be in a current status (sampled within the past 5 years) by the end of the 2017 

sampling season, with at least a limited record (3 or more years sampled).

Percent Fines

All current sites were categorized as High, Moderate, or Low fines, based on the average of all samples 

within the last 5 years. 

The Challis National Forest Land Resource Management Plan (USDA Forest Service, Challis National Forest, 

1987) includes the following Standards and Guidelines regarding fine sediments: “Impacts of activities may 

not increase fine sediment by depth (within critical reaches) of perennial streams by more than 2% over 

existing levels. Where existing levels are at 30% or above, new activities that would create additional 

stream sedimentation would not be allowed.” The Salmon National Forest Land Resource Management 

Plan (USDA Forest Service, Salmon National Forest, 1988) provides a goal of less than 20% fines in spawning 

gravels for anadromous habitat and less than 28.7% fines in spawning gravels for resident habitat.

These Forest Plan goals, standards, and guidelines are the basis for the High (>30%), Moderate (20 to 30%), 

and Low (<20%) fines thresholds presented in this analysis. Sites with high fines are considered to be 

impaired, although in some cases this may be the result of natural processes. 

Percent Fines (Average last 5 years) Number of sites Percent of sites

Low fines (<20%) 50 29.1%

Moderate fines (20-30%) 57 33.1%

High fines (>30%) 28 16.3%

Number of sites lapsed (no data last 5 years) 37 21.5%

TOTAL 172

Bank Stability

All current sites were categorized as High, Moderate, or Low bank stability, based on the average of all 

samples within the last 5 years. Standards provided in the PACFISH amendment to the Salmon and Challis 

Forest Plans establish a threshold of 80% bank stability for all watersheds, and 90% bank stability for 

PACFISH/INFISH priority watersheds. These standards are the basis for the High (>90%), Moderate (80 to 

90%), and Low (<80%) thresholds presented in this analysis. Sites with low bank stability are considered to

be impaired, although in some cases this may be the result of natural processes.

Analysis

Basic statistics were calculated for the 2011-2015 5-year average at all current sites. The average percent 

depth fines for all current sites was 23.6%, and the average percent stable banks was 87.8%.

A scatter plot of percent depth fines versus percent stable banks (2011-2015 5-year averages) shows no 

correlation between these two parameters at the 135 current sites. The majority of sites have greater than 

80 percent stable banks and less than 30% fines. Those sites that have less than 80% stable banks and/or 

greater than 30% fines are considered to be monitoring sites of concern. Only two sites have less than 80% 

stable banks AND greater than 30% fines, suggesting that a cause and effect relationship does not likely 

exist between bank stability and depth fines on the reach scale. Depth fines are more likely affected by 

conditions on a watershed scale.

Monitoring sites of concern

The following is a list of monitoring sites in which fines are greater than 30% and/or bank stability is less 

than 80%, based on the 2011-2015 average. Additional monitoring and site investigation are

recommended at these sites to more precisely determine the cause of the impairment.

SAMPLING PRIORITIES FOR 2016

The following is a summary of proposed sampling priorities for the 2016 monitoring season. High priority 

sites were identified with the goal of filling in dataset gaps at sites where management is occurring, and 

continuing annual or semi-annual monitoring at some sites where intensive management is occurring or 

conditions are changing. 2016 priorities are discussed on a site-by-site basis in this report. Because 

personnel and funding are limited, a total of only 64 sites were identified as high priority sites to be 

sampled in 2016.
