August Placer 1,2, 3 Plan WQPM: 

A buffer of 20-25 feet will be maintained during testing between 

areas of disturbance and Slab Creek (p. 3).

Wet area below the mine dump will not be impacted during this 

operation (p. 3).

NOTE: The adit water will be used but the adit will not be mined.

Effects

No potential for a discharge of pollutant into navigable waters 

because there is no surface hydrologic connection between the 

channel in this area and Slab Creek where it meets up with 

Greenhorn Creek. The channel is discontinuous and related to 

historic mining activity. 

Additional Forest Service WQPM

Adit-specific requirements:

1. Water from the adit shall be piped or trenched across bare soils and 

the mine dump to a settling pond. 

2. Settling and/or processing ponds shall not be built in mine dumps. 

Effects

Same as Alternative 2

activities and the stream channel (p. 4).

Effects

The effectiveness of the proposed buffer is uncertain because the 

description of the buffer zone in the Plan was not specific enough. 

Depending on the starting point the miner intended to use, there 

“may” or “may not” be a potential for a discharge of a pollutant into 

navigable waters. As a result of this uncertainty and lack of 

clarification, the worst-case scenario was used (Chapter 3, Figure 

3-1, Point A). In this scenario, there would be a potential for a 

discharge of pollutant into navigable waters.

2. The buffer width would be increased to 25 feet.

3. If rills develop in the 25-foot buffer zone then silt fences or other 

impediment would be placed within this zone to prevent sediment in 

the rills from reaching the channel.

4. To prevent sediment from reaching the channel during a high flow 

event that floods the valley floor, excavated material would be 

replaced into holes at the end of each season.

Effects

Discharge potential would be eliminated because the mining activities would now 

occur on a flat valley floor, and the buffer clarification and increase in buffer 

width would compensate for the lack of downed woody material and grasses. 

Ground cover is 80% plus and mostly a thin coating of pine needles. Valley 

floor has very little micro-topography and very little downed woody material. If 

rills form, then requirement #3 would effectively prevent sediment from reaching 

the creek. 

Burnt Lode/Placer 1 

(2 test holes – part 

adjacent to NFBR)

Plan WQPM

A vegetated buffer strip at least 25 feet wide will be maintained 

between the test site and the NFBR (p. 6).

Effects

There is the potential for a discharge of a pollutant into navigable 

waters, as defined by the CWA, for the reasons discussed in Big 

Elk/Red Dog Placer. 

Additional Forest Service WQPM

1. Measurement of the buffer would start at the edge of the conifer-valley 

floor boundary, extending 15 feet east into the trees.

2. To prevent sediment from reaching the channel during a high flow event 

that floods the valley floor, excavated material would be replaced into 

holes at the end of each season.

Effects

Discharge potential would be eliminated because mining activities would be 

removed from the annual floodplain. Recent gravels on the valley floor indicate 

that regular flows are reaching the valley floor. The gentle hillslope has good 

ground cover that would effectively trap sediment, thus preventing it from 

reaching the valley floor. Ground cover on the valley floor is estimated at 70%

A vegetated buffer strip at least 25 feet wide will be maintained 

between the test site and the NFBR (p. 6).

Effects

There is no potential discharge of a pollutant into navigable waters, 

as defined by the CWA because there is no surface hydrologic 

connection between this site and NFBR. The site is separated from

dredging (See Appendices 7A and 7B). 

2. To prevent sediment from reaching the channel during a high flow event 

that floods the valley floor, excavated material would be replaced into

3. No suction dredging would occur in Cub Creek

Effects

Discharge potential would be eliminated because buffer clarification puts the 

mining activities on the flat valley floor. The gentle topography combined with 

the presence of grasses and downed wood would provide sufficient sediment 

traps to prevent sediment generated by the operation from reaching the stream. 

Ground cover on the valley floor is at least 50% and is a mix of grasses and forbs. 

Area is heavily grazed. Lots of downed wood in the valley floor.

(Karissa)

Plan WQPM

None identified for this site or for the road construction.

Effects

There is the potential for a discharge of a pollutant into navigable 

waters, as defined by the CWA, as a result of road construction 

because of the location (on a steep hillside), extent (approx. 2000 

feet) of the proposed road , and the evidence of soil movement 

make it highly likely that sediment will move downslope into the 

NFBR during construction and maintenance.

Additional Forest Service WQPM

1.The road would be designed to meet Forest Service engineering 

specifications. 

2. Silt fences would be placed below the road construction.

Effects

The potential for a discharge of a pollutant into the NFBR remains for the same 

reasons stated in Alternative 2 though the impact may be less due to the Forest 

Service WQPMs. 

Camp Hale Placer Plan WQPM

.... no testing holes will be excavated closer than 25 feet from the 

creek. (p. 3)

Effects

No potential discharge of a pollutant into navigable waters, as 

defined by the CWA, is possible because the operation is more than 

300 feet from Camp Creek and the topography is flat. The 

proposed buffer is, therefore, not relevant.

buffers are, therefore, not relevant.

EJ Placer A, B, C, 

D, E

Plan WQPM

All test holes will be at least 25 feet from the high-water mark (p. 

3).

Ponds are located at least 50‟ from the river (p. 5).

A vegetated buffer strip of at least 25-feet wide and will be 

maintained between testing or mining area and the NFBR channel 

and 10 feet from the overflow channel along road 315 (p. 5) [EJ 

Placer B].

Effects

There is the potential for a discharge of a pollutant into navigable 

waters, as defined by the CWA, for the reasons discussed in Big 

Elk/Red Dog Placer. In addition, there are concerns about the 

location of the processing ponds, because the stream banks are 

composite (fines over a cobble/gravel/fine layer) and high in places. 

Banks are unstable when vegetation is absent due to their 

composition and height. 

EJ Placer E has a water quality concern as a result of the operation. 

May eliminate cold/cool water refugia in the NFBR which is 303d 

listed for temperature due to altering groundwater flow patterns.

Additional Forest Service WQPM

1. Measurement of the 25-foot buffer would start from the valley floor 

terrace-channel bank break in slope (See Appendix 1C, Figures 1 and 2 

for explanation of this feature). Where two terraces exist and the lower 

terrace is less than 25-feet wide, the count would start from the higher 

one. 

2. To prevent sediment from reaching the channel during a high flow event 

that floods the valley floor, excavated material would be replaced into 

holes at the end of each season.

3. EJ Placer E: The location of the processing ponds would be 

determined by the district hydrologist working with the operator.

4. EJ Placer B: Measurement of the 10-foot buffer would start from the 

top of the overflow channel bank. 

Effects

Discharge potential would be eliminated because the buffer clarification 

combined with the percent and type of ground cover and the flat topography 

would effectively trap any sediment generated by the activity and prevent it from 

being delivered to the stream.

EJ Placer A: Ground cover on the valley floor terraces is about 50% and is a mix 

grasses and forbs. 

EJ Placer B: Ground cover on the valley floor terraces is about 80% and is a mix 

of grasses and forbs.

EJ Placer C: Ground cover on the valley floor terraces is about 80% and is a mix 

of grasses and fords with some willows and alders. 

EJ Placer D: Ground cover on the valley floor terrace is about 100% and is a mix

of deep needles, grasses, forbs with an shrub understory of snowberry.

EJ Placer E: Ground cover on the valley floor terrace is about 100% and is a mix 

of dense grasses and forbs. There are areas of wetlands with sedges and rushes.

Gimlet Placer Plan WQPM

A ten-foot buffer will be maintained between test holes and the 

creek (p. 3).

Processing will take place at least 25 feet from the creek (p. 3).

Effects

There is the potential for a discharge of a pollutant into navigable 

waters, as defined by the CWA, for the reasons discussed in Big 

Elk/Red Dog Placer. 

Additional Forest Service WQPM

1. Mining operations on the west side of Gimlet Creek would be limited to 

the hillslope west of the old road. 

2. Mining operations on the east side of the creek would be limited to the 

non-stream side of the placer tailings. These tailings are located on the 

valley floor. As a result, the width of the buffer would vary. 

3. Buffer widths on the east side of the stream would vary because they are 

defined by the location of the tailings. Where tailings are not 

continuous, straw bales or silt fences would be placed in the open area to 

plug the break to prevent sediment from reaching the creek. 

4. To prevent sediment from reaching the channel during a high flow event 

that floods the valley floor, excavated material would be replaced into 

holes at the end of each season.

Effects

Discharge potential would be eliminated on the west side because the road on the 

west side would effectively trap any sediment that exits the hillside. Discharge 

potential is eliminated on the east side because the ground is flat and the river is 

bordered in many places by tailings. The tailings, straw bales, or silt fences 

would effectively block any sediment generated by the activity from entering 

Gimlet Creek. 

Ground cover on both sides of the creek is about 80% and is a thin layer of pine 

needles.

All mining sites will be located at least 10 feet from the channel (p. 

2).

Two off-channel settling ponds .... will be located at least 25 feet 

from the channel (p. 3). 

Effects

No potential for a discharge of sediment into navigable waters as 

defined by the CWA because Jackknife Creek is separated from any 

navigable waters by a huge tailings pile zone. However, given the 

ambiguity of the current buffer description, there is the potential for 

sediment to get into the Jackknife Creek as a result of the mining 

activity. 

Additional Forest Service WQPM

1. Measurement of the 10- foot buffer would start from the top of the old 

placer mine tailings that line the stream banks. 

Effects

Discharge potential would be eliminated because the topography between the 

creek and are to be mined is composed of old placer tailings and the ground has a 

lot of micro topography. Operating behind the tailings berm closest to the 

channel ill effectively trap any sediment. 

Ground cover is 80% plus and mostly a thin layer of needles. 

Gold Busters Placer Plan WQPM

Test runs of placer gravels will be settled in pond located at least 

30‟ from the creeks in each location (p. 3). 

At least a 20‟ buffer will be maintained between backhoe test holes 

and Pinus Creek or any springs located on the claims (p. 3).

Effects

No potential discharge of a pollutant into navigable waters, as 

defined by the CWA, because they are mining in the hillside, and 

their ponds are located away from the stream and are very stable. 

The hillside is more than 75 feet from the creek, and a bench is 

located between the hillside and the area of the operation which 

slopes gently down to the creek. (See letter from Kay White dated 

Feb 23, 2008 in which she clarifies the plan).

Testing will also take place in the Camp Creek meadow at least 25 

feet from the creek and back into the higher ground outside the 

meadow area (p. 3).

Settling/recycling ponds are also located in the dry draw near the 

spring (p. 6). No buffer for the spring stated.

Ponds will be located at least 25 feet from the creek (p. 6).

Note: it is unclear if the water in the ponds is coming strictly from 

groundwater, or if the groundwater will be supplemented with water 

from the creek and a spring at site #1. If supplemented, then the 

water levels in the ponds will be higher than groundwater. 

Effects

There is the potential for a discharge of a pollutant into navigable 

waters, as defined by the CWA, for the reasons discussed in Big 

Elk/Red Dog Placer. In addition, there are concerns about the pond 

given the characteristics of the stream banks. The bank sediments 

are fines overlying unconsolidated gravels. Banks are about 3-feet 

tall and unvegetated. 

The potential for ponds to create local zones of bank failure due to 

seepage depends on how full the ponds get with respect to the water 

surface elevation in the channel. If the ponds tap only into 

groundwater, then bank failure is not expected because the water 

elevation in the stream and the ponds will be the roughly the same. 

However, if the ponds are filled with water such that the water level 

in the ponds is higher than the stream water level, then bank failure 

is possible because the elevated water level in the ponds will result 

in a steeper hydraulic gradient that could result in localized bank 

seepage zones. Bank failures would occur as a result of the 

operation and would input sediment into the creek.

Additional Forest Service WQPM

1. When ponds tap only into groundwater, then ponds can be within 25 feet 

of the edge of the valley floor terrace-channel bank break in slope. 

However, if the ponds are filled with water such that the water level in 

the ponds is higher than the stream water level, then the stream banks 

perpendicular to the ponds and downstream of the ponds would be 

monitored for the development of seepage zones that may be the result 

of elevated waters levels in the ponds. If seepage zones are noted, then 

the ponds would be drained so that they are tapping only into 

groundwater.

2. Measurement of the 25-foot buffer for testing activity would start from 

the valley floor terrace-channel bank break in slope (See Appendix 1C, 

Figures 1 and 2 for explanation of this feature).

3. To prevent sediment from reaching the channel during a high flow event 

that floods the valley floor, excavated material would be replaced into 

holes at the end of each season.

Effects

Discharge potential would be eliminated because buffer clarification, when 

combined with the percent of ground cover and the flat topography, would

effectively trap any sediment generated by the activity and prevent it from being 

delivered to the stream.

Ground cover on the valley floor terrace is about 50% and is grasses with a shrub 

overstory of sagebrush.

2. The buffer width between mining excavation or drilling and the stream 

channel on the eastern side of the ridge would be increased to 50 feet 

from the top of the high-flow stream channel bank because this area is a

3. Silt fences or other impediments would be placed at least 10 feet from 

the top of the stream bank and between the channel and the mining

and silt fences or other impediment would effectively trap any sediment 

generated by the mining activity or drilling on the hillside and prevent it from 

being delivered to the stream channel located on the east side of the ridge. The 

clarification of the processing pond location would eliminate any concerns 

because the ponds would be distanced from the creek and separated from it by a

Additional Forest Service WQPM

1. Where old placer tailings line the stream bank, measurement of the 10-

foot buffer would start from the back edge of the tailings. 

2. In areas where no tailings line West Simpson Creek and there is a valley 

floor, the buffer would be increased to 25-foot buffer starting from the 

valley floor terrace-channel bank break in slope (See Appendix 1C, 

Figures 1 and 2 for explanation of this feature). 

3. In areas where the hillside feeds directly into the creeks, mining would 

occur up the hillslope at least 50 feet from the top of the stream bank, 

and silt fences or straw bales would be installed between the activity and 

the creek. 

Effects

Discharge potential would be eliminated because 1) where tailings are present, 

they would effectively trap any sediment behind them and prevent sediment from 

reaching the creek, 2) where tailings are absent but there is a flat valley floor 

terrace, the increase in buffer width, combined with the type of ground cover, 

would prevent it from reaching the creek, and 3) where the topography is a 

hillslope, the increase in buffer widths, combined with the amount of ground 

cover and the straw bales, would trap any sediment generated from the activity. 

Ground cover in the areas where the topography is flat is 50 to 100% and is a mix 

of grasses and needles. The ground cover varies in areas that are under conifers 

(higher % ground cover and largely needles) or in more open areas (lower % 

ground cover and more of a mix of needles and grasses). 

Ground cover in areas where the topography is a hillslope with conifers is 100%. 

The ground cover is a mix of primarily needles with some grasses.

Plan WQPM

Buffers a minimum of 10 feet wide will be maintained between 

excavations and stream channels; buffers a minimum of 25 feet 

wide will be maintained between processing activities and stream 

channels (p. 5).

Effects

There is the potential for a discharge of a pollutant into navigable 

waters, as defined by the CWA, for the reasons discussed in Big 

Elk/Red Dog Placer. In this case the area of concern is the 

wetland located below FS 1060. This wetland is not adit generated. 

NOTE: Operator will be opening adit and using the adit water. The 

adit discharges water into an adit-generated wetland. The adit 

waters go subsurface. Groundwater reemerges several times before 

reaching the road. There is a continuous channel between the adit 

and the wetland located below the road. The condition of the 

channel below the culvert outlet indicates that the channel does 

carry water at time. The channel ends in a wetland that is supported 

by groundwater. 

Additional Forest Service WQPM

1. The buffer width would be increased to 25 feet for excavations, and the 

measurement of the 25-foot buffer for excavations would start from the 

valley floor terrace-channel bank break in slope (See Appendix 1C, 

Figures 1 and 2 for explanation of this feature). 

2. Measurement of the 25-foot buffer for all processing activities would

start from the valley floor terrace-channel bank break in slope (See 

Appendix 1C, Figures 1 and 2 for explanation of this feature). 

3. The adit water shall be piped across bare soils and the mine dump to a 

settling pond. 

4. Settling and/or processing ponds shall not be built in mine dumps.

Effects

Discharge potential would be eliminated because the increase in buffer width, 

combined with clarification of where the buffer measurement begins, results in 

putting the activity either, 1) in the flat area or, 2) on a hillslope, but with flat 

topography between the channel and the activity. The buffer width, combined 

with the gentle topography in the buffer area and the moderate ground cover, 

would be sufficient to trap any sediment generated by the activity and prevent it 

from being transported to the channel and then to the wetland. 

Ground cover is about 100% and is mostly a thin layer of needles. Scattered 

grasses are present.

increase in buffer widths where tailings are absent, when combined with the flat 

valley floor, ground cover and tailings, would effectively trap any sediment 

leaving the site and prevent it from reaching the stream. Where tailings exist, 

they form an effective sediment barrier between the operation and the channel 

such that no sediment would be transported to the channel.

If lode values are economic to mine, a road approximately 1000 

feet or less in length will be constructed from the east side of the 

creek to the adit. The road will grade down the hillside to reach the 

adit, ending approximately 30 feet from the creek (p. 3).

The adit will be opened and mining will take place underground and 

also at the mouth of the adit leaving a 20-foot undisturbed buffer 

between the mining and creek (p. 3).

....ponds will be established at least 50 feet from the creek. An 

alternative processing site may be established high on the east 

hillside at least 100‟ from the creek (p. 3). 

NOTE: Miner plans to mine the adit which is discharging water.

On March 11, 2008 received a letter from the operator in which he 

stated the following: “...While mining is taking place underground, 

water will be piped through the working area so the working area is 

dry, and so the water stays clean. The pipeline will cross Simpson 

Creek and the adit water will flow into the settling ponds... We do 

not plan to discharge muddy water from the adit into Simpson 

Creek”

The letter also states that they will rock both sides of the creek 

approach and place logs in the stream and wetland area in order to 

minimize impacts to this area. These changes in the Plan eliminate 

the discharge concerns.

Processing ponds exist on the north side of the river (old dredge 

ponds) are off channel and located over 50 feet from the river (p. 3).

One set of ponds is located on the west end of the claims [on the 

north side], one is located on the east end [on the north side] over 

50 feet from the river and will be used for processing (p. 5). 

Off channel ponds are also located on the south side of the river just 

east of the bridge, over 50 feet from the river (p.5).

Plan and map indicate that there is mining on the north and south 

sides of the river. 

Effects

There is the potential for a discharge of a pollutant into navigable 

waters, as defined by the CWA, for the reasons discussed in Big 

Elk/Red Dog Placer, as well as whether they plan to mine in the 

wetlands and breach beaver dams as stated in their Plan. 

NOTE: The Plan states: Beaver dams will be removed so that the 

river does not flood into the mining area (p. 6). Removal of the 

beaver dams will release the sediment trapped behind the dam 

downstream and will result in increased turbidity and possible

burial of spawning gravels.

start at the valley floor terrace-channel bank break in slope (See 

Appendix 1C, Figures 1 and 2 for explanation of this feature). 

2. Measurement of the 50-foot buffer between the northern processing 

ponds and the creek would start at the valley floor terrace-channel bank 

break in slope (See Appendix 1C, Figures 1 and 2 for explanation of this 

feature).

3. Wetlands would have a 25-foot buffer with the buffer starting at the 

edge of the wetland vegetation.

4. The beaver dams would not be breached. Instead, beaver deceivers 

would be installed to keep the water levels in the beaver ponds at a level 

that would not flood the mining areas at high flow, while maintaining 

water storage capacity and trapping sediment. 

5. To prevent sediment from reaching the channel during a high flow event 

that floods the valley floor, excavated material would be replaced into 

holes at the end of each season.

Effects

Discharge potential would be eliminated with the buffer clarification because the 

valley floor is flat and there is sufficient ground cover and micro-topography in 

the proposed buffer zone to trap sediment generated by testing and processing. 

Discharge potential due to mining in the wetlands adjacent to the NFBR would be

because the wetlands would not be mined and would be buffered from activities.

Effects

Discharge potential would be eliminated because buffer clarification puts the 

entire buffer on the valley floor terrace or on the back side of the road. Both 

features are flat and wide enough to prevent any sediment that might be generated 

by the operation from being transported to the river. In addition, the flat valley 

floor has about 50 % ground cover. 

In addition, a buffer around the wetlands, which are located on the valley floor, 

would prevent sediment from getting into the wetlands which are adjacent to the 

NFBR.

Ground cover on the valley floor is about 50% and is mostly grasses.

Ground cover on the road is 0%.

NOTE: No buffer distances are stated for testing on the north and 

south sides of the NFBR.

Effects

There is the potential for a discharge of a pollutant into navigable 

waters, as defined by the CWA, for the reasons discussed in Big 

Elk/Red Dog Placer. In addition, the south bank of the middle ford 

is composed of fines.

The plan identifies buffer distances for processing but not for 

testing. While the Plan is ambiguous on where the buffer 

measurements start, but the sketch map indicates that testing areas 

will either be behind old placer tailings or separated from the creek 

by a road and a flat zone. 

4. The south bank of the middle ford would be rocked and sloped.

Effects

Discharge potential would be eliminated because all the activity is located behind 

tailings that line the stream banks. Therefore, it is not possible for sediment 

generated by the activity to be transported to the creek.

Ground cover is 80% plus and mostly a thin layer of needles.

Processing operations will located approximately 50 feet from the 

river (Letter dated March 7, 2008). This is an increase in distance 

over the Plan which stated that “ the processing operations will be 

conducted at least 25 feet from the creek (p. 6).”

NOTE: The plan states that the adit discharges water but a field 

visit found only one water source that is upslope of the adit. Water 

flows down the channel in front of the adit for a short distance and 

then goes subsurface. The zone mining engineer believes that water 

is backed up behind the material that has sealed off the portal. 

Operator will be opening adit and using the adit water. The adit 

discharges water into mining-created channel below the adit. The 

channel carries water for less than 100 feet before going dry. Water 

resurfaces in a wetland below the old mill site. A road marks the 

downslope end of the wetland. There is a channel below the road, 

but it is dry. 

Rocker Group Placer Plan WQPM

At least a 20-foot buffer will be maintained between the mining site 

and Greenhorn Creek and a 10-foot buffer between the mining site 

and Slab Creek (p. 3). 

Two off-channel settling/recycling ponds, ... and two smaller ponds 

are located over 50 feet from Greenhorn Creek and will be used for 

processing (p. 5). 

Effects

There is the potential for a discharge of a pollutant into navigable 

waters, as defined by the CWA, for the reasons discussed in Big 

Elk/Red Dog Placer, as well as the implied suggestion that the 

existing processing sites might be moved closer to the stream, and 

topography on the east side of the stream (see below). 

NOTE: The plan states that testing of the claims will take place on 

the east side of Greenhorn Creek. No buffer width for testing is 

specified for the east side. The east side of the creek is bordered by 

a hillslope in a lot of places that feed directly to the stream.

Additional Forest Service WQPM

 

1. The processing site and ponds would remain where they currently are 

located.

2. On the WEST side of Greenhorn Creek, silt fences would be installed at 

the 20-foot buffer because the topography slopes towards the creek, and 

the ground cover is limited to a thin layer of needles. Another option is 

to increase the buffer width to 50 feet, with silt fences needed only if 

rilling is noted in the 50-foot buffer. Measurement of the buffer would

start from the top of the low-flow stream bank (See Appendix 1C, 

Figures 1 and 2 for explanation of this feature).

3. On the EAST side of Greenhorn Creek where testing is proposed, 

topography is variable. Where there is no valley floor terrace and the 

hillside feeds directly into the creek, a silt fence would be installed at 

least 20 feet from the creek between the creek and testing. Another 

option is to increase the buffer width to 50 feet, with silt fences needed 

only if rilling is noted in the 50-foot buffer. Measurement of the buffer

mining buffer would start from the top of the old mine tailings that line 

the creek. Where tailings are absent, the measurement would be 

increased to 25 feet, and would begin from the valley floor terracechannel bank break in slope (See Appendix 1C, Figures 1 and 2 for 

explanation of this feature). Another option is to install a silt fence 10 

feet from the creek. No work is proposed for the south side of Slab 

Creek. 

Effects

Discharge potential would be eliminated because the combination of buffer 

clarifications, silt fences, working behind the tailings, and keeping the processing 

site at its current location would prevent any sediment from entering Slab Creek 

or Greenhorn Creek. 

Ground cover on the west side of Greenhorn Creek in the buffer zone is 80% or 

more, and is a thin layer of needles.

Ground cover on the east side of Greenhorn Creek in the buffer zone is 80 % or

Effects

Discharge potential would be eliminated because the buffer clarification places 

the activities on the valley floor where it is flat and provides a vegetated filter 

strip between the mining and processing areas and the stream. This filter strip is 

sufficient to trap any sediment generated by the activities.

Ground cover in the southern part of the operation is 40 to 50%. Ground cover in 

the north end of the operation is about 100%. Vegetation is grass and forbs.

hillslope where the ground becomes flatter.

Effects

Discharge potential is eliminated because all activity would take place in a flat 

area. Although ground cover is limited, the combination of topography and 

ground cover is sufficient to trap any sediment generated, preventing it from 

reaching the creek. In addition, the ponds are large, excavated and located in the 

flat area, and are therefore very stable.

Effects

Middle section: This section has two discrete topographic flat areas on the north 

side of Snow Creek. It has a narrow active floodplain with many small ponds 

and wetlands (referred to as “floodplain”). It also has a large, wide bench that is 

above the floodplain and is where the large processing ponds are located (referred

creek is gentle, and the valley width in between the road and creek 

is more than 50 feet.
