Behavior and Passage of Juvenile Salmonids during the 

Evaluation of a Behavioral Guidance Structure at Cowlitz 

Falls Dam, Washington, 2011

By Tobias J. Kock, Theresa L. Liedtke, Brian K. Ekstrom, Ryan G. Tomka, and Dennis W. Rondorf

Executive Summary

A radiotelemetry evaluation was conducted during April–October 2011 to describe movement 

patterns, forebay behavior, and passage of juvenile steelhead, coho salmon, and Chinook salmon at 

Cowlitz Falls Dam, Washington. The primary focus of the study was to describe fish behavior near a 

behavioral guidance structure (BGS) and floating surface collector (FSC) deployed upstream of Cowlitz 

Falls Dam. A secondary focus was to determine the proportion of tagged fish that were detected near 

spillbays 2 and 3 on the dam, because this location has been proposed for deploying weir boxes as an 

additional dam-based collection alternative in the future. Juvenile steelhead (Oncorhynchus mykiss), 

coho salmon (Oncorhynchus kisutch), and Chinook salmon (Oncorhynchus tshawytscha) were collected 

and tagged at the Cowlitz Falls Fish Collection Facility and transported upstream where they were 

released into the Cowlitz and Cispus Rivers. We radio-tagged and released 110 juvenile steelhead, 110 

juvenile coho salmon, and 110 juvenile Chinook salmon and monitored their movements in and around 

the BGS/FSC complex, at the dam, and downstream of the dam. We used detection records and a 

Markov chain model to calculate probabilities of movement between specific areas in the forebay of 

Cowlitz Falls Dam. These areas are referred to as states and the Markov chain model was used to create 

a series of tables, called transition matrices, that contained estimated probabilities of movement between 

states. These probabilities were insightful for understanding how radio-tagged fish moved near the BGS, 

FSC, and spillbays. 

Most tagged fish (89–91 percent) moved downstream of release sites (9 or 22 rkm upstream of 

the dam) and were detected in the dam forebay during the study period. Tagged fish that encountered 

the BGS on their first approach to the dam were distributed across the forebay, which supports the 

concept of using a BGS to concentrate fish near a collector entrance in the dam forebay. We found that 

14 percent of the steelhead, 18 percent of the coho salmon, and 17 percent of the Chinook salmon 

encountered the FSC discovery area without BGS guidance on their first trip through the forebay. The 

BGS guided 36 percent of the steelhead, 22 percent of the coho salmon, and 46 percent of the Chinook 

salmon to the FSC discovery area when fish first entered the forebay, which resulted in 40–63 percent 

(by species) of the tagged fish arriving at the FSC discovery area. Movement patterns along the BGS

showed that fish were likely to guide along the device, but also demonstrated the tendency of fish to 

move under the BGS and downstream to Cowlitz Falls Dam.
2 

Tagged fish that arrived at Cowlitz Falls Dam were distributed across the dam face but a high 

percentage of each species (65 percent of steelhead; 61 percent of coho salmon; 71 percent of Chinook 

salmon) arrived on the northern side of the dam. Movement probabilities near spillbays 1 and 4 showed 

a strong preference for tagged fish to move from the outer edges of the dam towards the center of the 

dam where they were detected at the debris barrier (range of probabilities = 0.690–0.841). We found 

that 76 percent of the steelhead, 61 percent of the coho salmon, and 92 percent of the Chinook salmon 

were detected at spillbays 2 or 3 during the study. This behavior supports the strategy of weir box 

deployments in spillbays 2 and 3 for future dam-based collection options. Tagged fish that arrived at the 

dam commonly moved upstream and were detected at the BGS or FSC discovery area. This behavior 

provided a secondary opportunity for fish to encounter the FSC discovery area and we found that in 

total, 72 percent of the steelhead, 48 percent of the coho salmon, and 92 percent of the Chinook salmon 

were detected near the FSC while residing in the forebay. Overall, 88 percent of the steelhead, 76 

percent of the coho salmon, and 95 percent of the Chinook salmon that entered the forebay were 

detected near the FSC or in spillbays 2 and 3. 

Turbine passage was the most common passage route for tagged fish at Cowlitz Falls Dam 

during 2011. We found that 40 percent of the steelhead, 52 percent of the coho salmon, and 33 percent

of the Chinook salmon passed through turbines. An additional 22 percent of the steelhead and 32 

percent of the coho salmon passed through turbines or spillways when both passage routes were 

available. Fish collection numbers were relatively low during 2011 compared to long-term averages. In 

total, 37 percent of the steelhead, 14 percent of the coho salmon, and 23 percent of the Chinook salmon 

that entered the forebay were collected, primarily through collection flumes. The FSC collected a single

radio-tagged fish (a Chinook salmon) in 2011. 

Introduction

A variety of approaches have been used since 1998 to improve juvenile salmon collection at 

Cowlitz Falls Dam, Washington (fig. 1). Initial studies found that turbine entrainment was relatively

high (45 percent; juvenile steelhead) and demonstrated that the proportion of tagged fish that entered 

spillbays 2 and 3, where collection flumes are located, was insufficient to meet collection goals (Adams 

and others, 1999). Efforts to improve collection during subsequent years included installing strobe lights 

in an attempt to deter fish from passing through turbines, and evaluating new spillbay entrance 

configurations to increase flume discovery rates by juvenile salmon (Evans and others, 2001; Hausmann 

and others, 2001; Kock and others, 2009). Hausmann and others (2001) found that spillbay entrances, 

which were 6.1 m wide and 4.9 m deep, had substantially higher flume discovery rates than spillbays 

configured with the original narrow-deep entrances (1.2 m wide and 11.0 m deep). Collection numbers 

at the flume entrances were still lower than desired so efforts were made to install new flared-rounded 

flume entrances to control flow acceleration upstream of the flumes. However, these modified flume 

entrances were tested during 2001 and 2003 and showed limited promise for substantial increases in fish

collection numbers (Hausmann and others, 2001; Farley and others, 2003; Perry and others, 2004). 

Results from these efforts eventually lead to the development of two prototype collection devices, a fish 

screen and a weir box (Kock and others, 2007; Liedtke and others, 2007, 2009, 2010). The fish screen 

was evaluated during four collection seasons (2006–09) and had marginal collection success (Kock and 

others, 2007; Liedtke and others, 2007, 2009, 2010). The weir box and the fish screen were deployed 

simultaneously during 2009 and the weir box was more effective at collecting fish than the fish screen

(Liedtke and others, 2010). Based in part on these findings, the fish screen was abandoned as a potential 

collection device, but the weir box continues to be considered for future evaluations. During 2010, 

Tacoma Power developed a prototype floating surface collector (FSC) and behavioral guidance structure 
3 

(BGS) that were located upstream of the dam (HDR, 2010). The BGS/FSC concept was based on the 

premise that juvenile salmon would encounter the BGS and be guided downstream to the FSC entrance 

for collection. Locating the FSC upstream of the dam provided two distinct advantages for juvenile 

salmon collection at Cowlitz Falls Dam. First, fish could be collected prior to encountering dam passage 

routes (that is, turbines or spillways) that contribute to lost collection opportunities at the dam. Second, 

the BGS/FSC could be operated simultaneously with collection devices on the dam to maximize 

collection numbers. 

During 2011, the influences of the BGS and FSC on juvenile salmonids in the forebay of 

Cowlitz Falls Dam were evaluated using radiotelemetry. This evaluation focused on two specific 

objectives developed by Tacoma Power. The first objective was to determine the proportion of radiotagged juvenile salmonids that encountered the FSC discovery area during 2011. The prototype FSC 

that was used during 2010 and 2011 is similar in concept, but different in design and scale, than the FSC 

that is envisioned for future collection efforts at Cowlitz Falls Dam. The prototype FSC was located 

approximately 60 m (200 ft) upstream of the dam near the north shore (fig. 2) and operates using less 

than 20 ft3/s inflow. The proposed FSC may be located near the current FSC location, but would operate 

using much higher inflow (proposed minimum of 500 ft3/s). Given the substantial differences in 

operating conditions between the prototype FSC and the planned FSC, high collection rates through the 

prototype device in 2011 were not expected. Rather, the number of juvenile salmon that encountered the 

prototype FSC (that is, discovery rate) in 2011 would be used to determine if anticipated discovery rates

of the proposed FSC would warrant the development and operation of the device in future years. 

Behavioral data for juvenile salmon along the BGS also were considered to be important for the 2011 

evaluation to determine if this device could effectively increase discovery rates of the FSC by juvenile 

salmon. The second objective for the 2011 evaluation was to determine the proportion of juvenile 

salmon that encountered entrances to spillbays 2 and 3 at Cowlitz Falls Dam where prototype weir 

boxes could be deployed during future years (fig. 2). 

Methods

BGS, FSC, and Fish Collection Facility

The BGS consisted of 21 individual panels that were 6.1 m (20 ft) in length and 3.0 m (10 ft) 

deep. For reference, BGS panels were numbered from 1 to 21, beginning at the downstream end near the

FSC (fig. 3). The BGS panels were solid steel plates supported at the surface by four large floats (fig. 3). 

Rubber inserts spanned gaps between individual BGS panels to provide a continuous barrier to fish 

passage in the upper 3.0 m of the water column. One small gap (<2 m) in the BGS was located between 

panels 2 and 3 where the structure was designed to break away during high flows to prevent damage to 

the BGS. The BGS was deployed to intercept downstream-migrating juvenile salmon and guide them 

towards the entrance to the FSC. Fish could move downstream of the BGS by: (1) moving between the 

FSC and the north shoreline; (2) moving through the space between the downstream end of the BGS and 

the FSC; (3) moving through the space between panels 2 and 3; (4) moving through the space between 

the upstream end of the BGS and the south shoreline; or (5) sounding beneath the FSC or BGS.

The FSC was located near the downstream terminus of the BGS to provide a collection location

where BGS-guided fish could be collected. The FSC used during 2011 had an entrance that was 1.8 m 

wide and 2.0 m deep. The width and depth of the FSC decreased in a downstream direction to the point 

where the FSC attached to a 0.6 m diameter submerged pipe that transported collected fish from the 

FSC to the fish facility. Inflow to the FSC was approximately 0.57 m3

/s (18 ft3/s) during 2011. 
4 

Collection of juvenile salmon at Cowlitz Falls Dam during 2011 (April–September) was 

accomplished using the FSC and two collection flumes inside spillbay 2 (fig. 2). Spillbays are numbered 

from north to south (fig. 2). The fish facility began operating on April 16, 2011, and was operated 

continuously until September 10, 2011. Collection flumes inside spillbay 2 were operated (0.60 m3/s 

apiece; 20 ft3/s) during the entire collection season. Flumes inside spillbay 3 were not operated because 

the FSC and spillbay 2 flumes provided the maximum amount of flow that could be handled by the fish 

facility. The FSC operated during most of the collection season with the following exceptions: (1) from 

May 15, 2011, to May 20, 2011, when high flows precluded operating the BGS, and (2) from August

30, 2011, to September 1, 2011, when the FSC was temporarily shutdown. 

Fish Collection, Tagging, and Release

 Juvenile steelhead, coho salmon, and Chinook salmon were collected and tagged with radio 

transmitters at the fish facility during 2011 (tables 1–3). Fish were collected for tagging every 5 d during 

the middle 95th percentile of the historical run timing for each species (April 24–June 11 for steelhead; 

May 12–July 9 for coho salmon; June 27–August 23 for Chinook salmon). The fish facility did not 

collect sufficient numbers of juvenile steelhead and coho salmon to meet the tagging request during 

some of the scheduled collection dates, resulting in some fish being tagged beyond the middle 95th

percentile of the run for these species (tables 1–2). The 2011 run timing of juvenile Chinook salmon at 

Cowlitz Falls Dam was substantially later than in previous years (John Serl, Washington Department of 

Fish and Wildlife, oral commun., 2011). As a result, tagging of juvenile Chinook salmon was delayed 

for nearly a month before sufficient numbers of fish were collected to meet our tagging needs (table 3).

All Chinook salmon tagging occurred during the 95th percentile of the historical run timing but within a 

shorter window than planned. 

We used radio transmitters (Model NTC-M-2; Lotek Wireless Inc.

©; Newmarket, Ontario, 

Canada) that had an operating life of about 50 d (based on specifications from the manufacturer and a 

taglife study) and weighed 0.43 g in air. All tagged fish weighed equal to or greater than 8.6 g (in air) to 

insure that the transmitter weight did not exceed 5 percent of the fish’s body weight. We tagged 110 fish 

per species during the study (tables 1–3). Transmitters were surgically implanted (Adams and others, 

1998) and tagged fish were held for approximately 24 h prior to release. 

Following the 24 h recovery period, tagged fish were released into the Cowlitz or Cispus Rivers, 

upstream of Lake Scanewa (fig. 1). Tagged fish were transported in an aluminum transport container 

(1,189 L; oxygen supplied) to release sites on the Cowlitz and Cispus Rivers. Release sites were 

selected to insure that fish were released slightly upstream of the reservoir boundary in Lake Scanewa.

The Cowlitz River release site was about 22 river kilometers (rkm) upstream of Cowlitz Falls Dam and 

the Cispus River release site was about 9 rkm upstream of the dam. When possible, release groups were 

split evenly between each release site on a given release date. On dates when an odd number of fish 

were tagged, the larger release group was released on an alternating schedule between release sites to 

insure that 55 tagged fish (of each species) were released at each site during the study period. 

Radiotelemetry System

We established aerial monitoring arrays throughout the study area to monitor movement patterns 

of tagged fish in Lake Scanewa, in the forebay, and downstream of Cowlitz Falls Dam. Aerial 

monitoring sites were located on the Cowlitz River (19.7 rkm upstream of Cowlitz Falls Dam), Cispus 

River (3.4 rkm upstream of Cowlitz Falls Dam), and on Lake Scanewa (3.9 rkm upstream of Cowlitz 

Falls Dam; 1.3 rkm upstream of Cowlitz Falls Dam; fig. 1). Four additional aerial sites monitored the 

forebay of Cowlitz Falls Dam. Monitoring downstream of the dam consisted of two sites that were 
5 

located in the dam’s tailrace (0.2 rkm and 0.3 rkm downstream of Cowlitz Falls Dam), and one site at 

Taidnapam Bridge (4.8 rkm downstream of Cowlitz Falls Dam; fig. 1). Aerial monitoring sites consisted 

of a pair of three-element aerial antennas connected to a telemetry receiver (Model SRX 400©; Lotek 

Wireless Inc.©, Newmarket, Ontario, Canada; Orion receiver©; Grant Systems Engineering, King City, 

Ontario, Canada). 

Underwater monitoring arrays were established on the BGS, FSC, and on Cowlitz Falls Dam to 

monitor fine-scale movements of tagged fish. Underwater antennas were installed 1.8 m below the 

surface (hereafter shallow BGS antennas) on the upstream and downstream sides of each BGS panel

(fig. 4). Underwater antennas also were installed 6.1 m below the surface (hereafter referred to as deep 

BGS antennas) on BGS panels 3–21 to detect fish that passed under the device. This configuration 

resulted in six shallow detection areas along the upstream and downstream sides of the BGS and FSC, 

respectively, and five deep detection areas beneath the BGS. Two underwater antennas also monitored 

the area between the FSC and the north shore for fish moving around the FSC (fig. 4). Underwater 

antennas were deployed 1.8 m below the surface at Cowlitz Falls Dam to monitor near-dam behavior of 

tagged fish (fig. 5). Detection areas at the dam included: (1) the debris barrier (antennas 23–27); (2) 

spillbay 1 (antenna 31); (3) spillbay 2 (antennas 30 and 33); (4) spillbay 3 (antennas 29 and 32); and (5) 

spillbay 4 (antenna 28; fig. 5). Underwater antennas were not deployed north of spillbay 1 or south of 

spillbay 4, which left approximately 18 and 32 m, respectively, that were unmonitored on the outer 

edges of the dam (fig. 2). Underwater antennas were range-tested prior to the study to insure that 

detection patterns were appropriate for study objectives (appendix A). 

Data Analysis

Data Processing

A dataset was created by combining all telemetry detection records, the tagging and release data, 

river flow data, and dam operations data for the study period. This dataset was rigorously proofed to 

create a final dataset for analysis. We used the SAS statistical package (SAS, 2008) to remove non-valid 

detection records from the preliminary dataset. Individual detection events were removed from a fish’s 

detection record if that detection event: (1) occurred prior to the known release time for a given fish 

(that is, fish that were detected during transport); (2) occurred more than 63 d (anticipated maximum tag 

life) after the release time for a given fish; or (3) the signal power assigned by the telemetry receiver

was less than 100 on receivers monitoring aerial antennas in the forebay of Cowlitz Falls Dam. 

Additionally, we programmed SAS to remove detection events from a fish’s detection record if there 

were not at least two detections within a 15-min period at a given detection location. Following 

preliminary processing with the automated proofing program, detection records were manually proofed 

by USGS staff. Manual proofers reviewed each fish’s detection record to insure that the automated 

proofing process removed all erroneous records. If non-valid detection events were identified by the 

proofer, the records were removed. Following manual proofing, the dataset was considered final. In 

some cases, external data were available for validating detection events in the final dataset. For 

example, we recorded the transmitter identification for every tagged fish that was collected at Cowlitz 

Falls Dam during the 2011 collection season. These data were then cross-referenced with dam passage 

data to verify that detections were accurately recorded. 

Detections and Fish Movement Patterns

Detection records were analyzed to determine the number of tagged fish using specific areas 

near the BGS, FSC, and the dam to understand fish distribution and movement patterns. For example, 
6 

the final dataset was queried to determine the number of fish (of each species) that were detected in the 

forebay of Cowlitz Falls Dam. These data were then compared to the number of fish released to 

determine the proportion of tagged fish that successfully moved downstream from release sites to the 

forebay. Travel times were calculated by subtracting the release date and time (for each fish) from the 

first date and time of detection in the forebay of Cowlitz Falls Dam. First detection events on individual 

antennas on the BGS and FSC provided information about the horizontal and vertical distribution of 

tagged fish when they first encountered the BGS/FSC complex. The final dataset also was partitioned 

by diel period (that is, day or night) and dam operating condition (that is, spill or no spill) to understand 

trends in fish behavior under these scenarios. Diel periods were defined using sunrise/sunset data 

obtained from HDR (2010). Hourly dam operating conditions were assigned based on Cowlitz Falls 

Dam operating records. Operating conditions during the study period included: (1) two turbines 

operating with spill; (2) two turbines operating without spill; (3) Unit 1 operating with spill; (4) Unit 1 

operating without spill; (5) Unit 2 operating with spill; (6) Unit 2 operating without spill; (7) spill only

(no turbine discharge); and (8) no operations (that is, no dam discharge). 

To categorize fish as having discovered the FSC for our analysis, we first had to define the 

spatial boundaries of the FSC. The goal of the BGS is to guide fish to an area where they encounter flow 

conditions created by the FSC so that they have the opportunity to be collected through the device. 

Hydraulic data from the forebay were not available to help determine where the extent of the FSC flow 

effects were during 2011 so we used two FSC discovery definitions to provide a range of observations 

when considering BGS guidance and FSC discovery rates. The underwater antennas used for our 

primary definition of the FSC discovery area included antennas 18–22 (fig. 6). These antennas 

monitored the FSC (antennas 20 and 22), the area between the FSC and the north forebay shore (antenna 

21), and the first two BGS panels located upstream of the BGS (antennas 18–19; fig. 6). This definition 

will hereafter be referred to as the small FSC discovery area. The second definition of the FSC included 

all antennas previously described along with antennas 6, 11, and 17, which increased the spatial 

boundaries of the FSC to include the first six BGS panels upstream of the device (fig. 6). This definition 

will hereafter be referred to as the large FSC discovery area. 

Markov Chain Analysis 

 We conducted a Markov chain analysis to describe movement patterns of tagged fish near the 

BGS, FSC, and Cowlitz Falls Dam. The use of Markov chain models has increased during recent years

due to developments in probability theory and stochastic modeling (Grinstead and Snell, 1997; Lindsey, 

2004). A Markov chain can be used to describe processes where observations can be grouped into a 

series of finite states where movements between states are possible. An individual movement between 

states is described as a “step”, and the overall sum of steps within the Markov chain are represented as a 

series of probabilities of moving between each state. For our analysis, individual states were defined by 

the locations of underwater antennas in the forebay of Cowlitz Falls Dam. Steps were defined as

physical movements by tagged fish between these locations. Movements between states were 

summarized to create tables of movement probabilities (transition matrices; Grinstead and Snell, 1997) 

that represented the probability of moving from a given state at time t, to another state at time t + 1. 

These transition matrices are the primary product from the Markov chain analysis in this report and 

probability data from these tables are used to describe movement patterns of tagged fish during the 

study period. 
7 

Underwater antennas were grouped to create 12 states that were used in the Markov chain 

analysis. We chose to group antennas, rather than use individual antenna locations to define states, for 

several reasons. Transition matrices become increasingly complex with increasing numbers of states and 

sample sizes within each state generally decrease as the number of states increase. The goal of the 

Markov chain analysis was to provide a probability framework to better understand behavior patterns of 

tagged fish near the BGS, FSC, and dam. Probability data can be very insightful for understanding 

movement patterns of tagged animals, but these data can be also uninformative when sample sizes are 

small. Grouping antennas into specific areas of interest allowed us to create a series of limited but

biologically meaningful states with sufficient data to provide reliable estimates of movement patterns 

during the study. Using this approach, we defined 12 states. The BGS was divided into four states that

included the south upstream BGS state, south downstream BGS state, north upstream BGS state, and 

north downstream BGS state (fig. 7). Antennas on the FSC and on the first two BGS panels upstream of 

the FSC were grouped to create the FSC state (fig. 7). Antennas that monitored the area between the 

FSC and the north forebay shore defined the north FSC gap state (fig. 7). Underwater antennas at the 

dam were grouped to create the debris barrier state, spillbay 1 state, spillbay 2–3 state, spillbay 4 state, 

fish facility state, and tailrace state (fig. 7). Tagged fish could make multiple movements between states 

in the forebay until they entered the fish facility state, tailrace state, or their transmitter expired.

We parsed the detection data into two datasets for the Markov chain analysis. To create these 

datasets, detection records were divided based on the first detection event for each fish on underwater 

antennas at Cowlitz Falls Dam. The first dataset consisted of the first underwater antenna detection at 

the dam along with all other underwater antenna detections that occurred prior to that first near-dam 

detection event. This dataset (hereafter approach data) consisted of detection events on the BGS, FSC, 

and the first detection at the dam, which comprised the first trip through the forebay for each tagged 

fish. This dataset was summarized to generate probabilities of fish encountering various states along the 

BGS and FSC, guiding along the BGS, and moving to the dam during their first trip through the 

forebay. The second dataset (hereafter residence data) consisted of all detection records that occurred 

after the initial near-dam detection event and included movements along the dam, return trips to the 

BGS and FSC, and passage routes used by tagged fish. 

Chinook Salmon Data

Radio-tagged Chinook salmon were monitored through mid-October when all radio transmitters 

had expired, and the Cowlitz Falls Fish Collection Facility stopped operating on September 10, 2011. 

We assumed that forebay conditions changed substantially when the fish facility was not operating 

because flow through the FSC and surface collection flumes in spillbay 2 was no longer available for 

fish to orient to. Given this assumption, we did not include forebay detection records of juvenile 

Chinook salmon in our analyses if detection events occurred after the fish facility closed. Therefore, 

results that appear in this report for juvenile Chinook salmon only include data that were collected prior 

to the fish facility closure, with one exception. Dam passage routes were assigned for tagged Chinook 

salmon if tagged individuals passed the dam, or remained upstream of the dam, after the fish facility 

stopped operating.

Results

River Flows and Dam Operations

River flows in the upper Cowlitz River were within the normal range during April–June, but 

July and early August flows were nearly twice as high as flows typically observed during this period 

from 2000 to 2010 (fig. 8). Mean daily river flows were approximately 5,000 ft3

/s when the fish facility 

began operating (April 16) and peaked at 17,200 ft3/s on May 16, 2011 (fig. 8). River flows generally 

ranged between 6,000 and 10,000 ft3/s during April–June (fig. 8). However, the combined effects of a 

substantial snowpack, cooler than normal conditions, and a wet spring resulted in an extended runoff 

period, which lead to higher than normal flows during July and August (fig. 8). 

Operating conditions at Cowlitz Falls Dam consisted primarily of two-turbine or one-turbine 

operations intermixed with spillway operations when river flows exceeded turbine capacities. Typically, 

Cowlitz Falls Dam operates both turbines when river flows are in the 4,000–10,000 ft3/s range. This was 

the operating condition during 59 percent of the 2011 fish collection season (fig. 9). Spillbays passed

additional water at the dam when river flows exceed 10,000 ft3/s and this condition occurred on 11 

percent of the days that the fish facility operated in 2011 (fig. 9). Dam operations are restricted to a 

single turbine when river flows are lower than 4,000 ft3/s, which happened on 30 percent of the 

collection days in 2011. During July and August of some years, river flows are so low that there are 

periods when no turbines are operated. This allows water to be stored in Lake Scanewa and results in 

intermittent turbine operations. Because river flows were higher than normal during July and August 

2011, intermittent turbine operations were relatively uncommon. Intermittent turbine operations 

happened on 5 days (August 29, September 2, September 4, September 6, and September 8) and the 

average length of no-flow periods at the dam was 5.4 h on each of these days. 

Detections and Behavior Patterns

Forebay Detections and Travel Time

Most of the tagged juvenile salmon moved downstream from the release sites and were 

subsequently detected on aerial or underwater antennas in the forebay of Cowlitz Falls Dam. A total of 

98 juvenile steelhead (89 percent; appendix B) were detected at Cowlitz Falls Dam during the study and 

their median travel time from release to the forebay was 18.4 h (range = 4.6–142.2 h). Median forebay 

residence (last detection event in the forebay-first detection event in the forebay) time for juvenile 

steelhead was 34.6 h (range = 0.07–598.3 h). A total of 91 percent (100 fish; appendix B) of the juvenile 

coho salmon were detected at Cowlitz Falls Dam during the study, and their the median travel time was 

20.5 h (range = 3.8–406.0 h). Median forebay residence time for juvenile coho salmon was 2.7 h (range 

= 0.02–224.7 h) during 2011. Most juvenile Chinook salmon (90 percent; 99 fish; appendix B) arrived

in the forebay of Cowlitz Falls Dam following release and their median travel time was 51.7 h (range = 

13.8–501.0 h). Median forebay residence time for juvenile Chinook salmon was 191.0 h (0.04–1215.0 

h). 
9 

Upstream Trips

Detection data were examined to determine how many tagged fish moved upstream into Lake 

Scanewa after being detected in the forebay of Cowlitz Falls Dam (hereafter upstream trips). We found 

that most steelhead and coho salmon remained in the forebay whereas Chinook salmon typically made 

numerous upstream trips following forebay entry. Most steelhead (77 percent) did not move upstream 

after entering the forebay of Cowlitz Falls Dam although a few fish made at least one upstream trip 

during the monitoring period (table 4). Nearly all coho salmon (95 percent) remained in the forebay and 

the five fish that did move upstream only made one trip apiece (table 4). Chinook salmon typically made 

numerous upstream trips during the study. Only 19 percent of the tagged Chinook salmon remained in 

the forebay following entry and more than one-half of the Chinook salmon (54 percent) made at least 

three upstream trips (table 4).

First Detections at the BGS

Forebay detection records were analyzed to determine the vertical and horizontal distribution of 

tagged fish when they first encountered the BGS or FSC. In total, 81 steelhead, 76 coho salmon, and 95 

Chinook salmon were detected by underwater antennas on the BGS or FSC following forebay entry. 

Some fish were undetected at the BGS and others entered the forebay when the BGS was not in position 

due to high spring flows. Most fish were first detected on the shallow upstream BGS antennas (72 

percent of the steelhead; 57 percent of the coho salmon; 69 percent of the Chinook salmon; figs. 10–12).

Most tagged fish were first detected at the BGS (85 percent of the steelhead; 77 percent of the coho 

salmon, and 82 percent of the Chinook salmon; figs. 10–12) and not at the small FSC discovery area. 

Underwater antennas on the BGS were grouped into five zones (Zones A–E; fig. 4) and first detection 

events at these zones indicated that tagged fish were spread across the forebay when they first 

encountered the BGS. In most cases, 10–20 percent of the tagged fish that encountered the BGS were 

detected in each of the five BGS monitoring zones (figs. 10–12). 

First detection events were grouped by diel period (day and night) and dam operating conditions 

to determine if fish behavior varied substantially under these conditions (figs. 13–15). Steelhead 

detection events occurred during three dam operating conditions, which included: (1) Unit 1 operating 

without spill; (2) both turbines operating without spill; and (3) both turbines operating with spill (fig. 

13). Coho salmon detection events occurred during two operating conditions, which included: (1) both 

turbines operating without spill; and (2) both turbines operating with spill (fig. 14). All Chinook salmon 

detection events occurred when Unit 1 was operating without spill. Some differences were apparent in 

first detection events that occurred during the various diel and dam operating conditions but in most 

cases sample sizes within each group were relatively small (<10 fish; figs. 13–15). In general, the 

largest differences in the locations of first detections during day and night periods occurred at the small 

FSC discovery area and Zone E. For all three species, the percentage of first detections at the small FSC

discovery area at night was double those that occurred during the day (figs. 13–15). For coho and 

Chinook salmon, Zone A showed a trend similar to the FSC, with twice as many detections at night 

compared to daytime periods. The opposite trend was observed at Zone E, where twice as many coho 

and Chinook salmon were first detected during the day compared to night (figs. 14–15). The largest 

difference in first detections for steelhead by dam operating condition occurred in Zone A. Fewer 

steelhead were detected in this zone during two turbine operations with no spill compared to the other 

two operations (fig. 13). The largest difference in first detections for coho salmon occurred at the FSC. 
10

During spill conditions, 5 percent of the tagged coho salmon were first detected at the small FSC

discovery area, but 28 percent of fish were first detected at the small FSC discovery area during periods 

without spill (fig. 14). Spill conditions also appeared to concentrate coho salmon in the center of the 

forebay, with fewer first detections at both the FSC and Zone E. 

Effects of Release Site

We compared travel times (from release sites to the dam forebay) and first detection patterns 

along the BGS for tagged fish from the two release sites to determine if a release site effect was 

apparent during the study period. Travel times from the Cowlitz River and Cispus River release sites to 

the forebay of Cowlitz Falls Dam were compared (using a Wilcoxon-Mann-Whitney test) to determine 

if average travel times differed between the release sites. We found no difference in reservoir travel 

times from the two release sites for steelhead (P = 0.077), coho salmon (P = 0.154), or Chinook salmon 

(P = 0.925). First detection events along the BGS (using zones shown in figs. 10–12) were compared for 

each species using Fisher’s exact test to determine if the horizontal distribution of tagged fish differed 

between release sites during the study. We found no difference in distributions of tagged steelhead (P = 

0.303), coho salmon (P = 0.748), or Chinook salmon (P = 0.871) along the BGS based on first detection 

events. These results demonstrated that travel times from the two release sites were similar during our 

study period and that tagged fish from each release site were distributed similarly across the forebay 

when they first encountered the BGS. Given these findings, we did not evaluate release site effects in 

subsequent analyses in this report. 

BGS Guidance

To determine the effectiveness of the BGS at guiding fish to the small FSC discovery area, we 

examined detection records of tagged fish during their initial encounter with the BGS. We found that 14 

percent of the steelhead, 18 percent of the coho salmon, and 17 percent of the Chinook salmon 

encountered the small FSC discovery area on their first approach without BGS guidance (fig. 16). The 

BGS successfully guided (from the BGS to the FSC) 36 percent of the steelhead, 22 percent of the coho 

salmon, and 46 percent of the Chinook salmon during their first encounter with the BGS (fig. 16). In 

total, 50 percent of the steelhead, 40 percent of the coho salmon, and 63 percent of the Chinook salmon 

were detected at the small FSC discovery area on their first trip through the forebay by either 

encountering the small FSC discovery area directly, or being guided to the FSC by the BGS (groups 

A+B; fig. 16). Additionally, 26 percent of the steelhead, 25 percent of the coho salmon, and 20 percent

of the Chinook salmon were partially guided by the structure (fig. 16). Partial guidance was defined as 

moving at least one zone closer to the small FSC discovery area from a fish’s initial detection location 

on the BGS. One tagged steelhead and one tagged Chinook salmon encountered the BGS and moved 

back upstream into Lake Scanewa. The remaining tagged fish were either unguided by the BGS (15 

percent of the steelhead; 17 percent of the coho salmon; 11 percent of the Chinook salmon) or were 

undetected at the BGS prior to arriving at the dam (8 percent of the steelhead; 18 percent of the coho 

salmon; 4 percent of the Chinook salmon; fig. 16). 

 
11

We also examined BGS guidance and FSC discovery using the large FSC discovery area 

definition, which included the first six BGS panels located upstream of the device (fig. 6). As expected, 

using this larger area for FSC detection resulted in increased FSC encounters and BGS guidance rates 

for all species (fig. 17). In total, 74 percent of the steelhead, 55 percent of the coho salmon, and 81 

percent of the Chinook salmon either encountered the large FSC discovery area directly, or were guided 

by the BGS on their first forebay trip (groups A+B; fig. 17). The percentage of partially guided fish and 

fish that were unguided by the BGS decreased. There was no change in the percentage of fish that 

returned upstream, or were undetected at the BGS during their first forebay trip (fig. 17). 

First Detections at Cowlitz Falls Dam

We examined the pattern of first detection events of individual fish using underwater antennas 

on the debris barrier and along the face of the dam to determine the horizontal distribution of tagged fish 

when they first arrived at Cowlitz Falls Dam. Most tagged steelhead (65 percent), coho salmon (61 

percent), and Chinook salmon (71 percent) were first detected on the northern side of Cowlitz Falls 

Dam (antennas 23, 24, 30 and 31; table 5). We also examined first detection patterns during day and 

night periods and under different dam operating conditions. First detection events on the northern side 

of the dam showed a diel trend for steelhead and coho salmon. During daytime hours, steelhead and 

coho salmon were more likely to be first detected on the northern side of the debris barrier (antennas 

23–24) whereas nighttime detections largely occurred at spillbay 1 (tables 6–7). There are other 

differences in first detection events for steelhead, coho salmon, and Chinook salmon but sample sizes at 

several detection locations are very small so these results should be interpreted cautiously (<5 fish; 

tables 6–8).

Detection Patterns Near Proposed Collection Entrances

 We examined several detection scenarios to understand fish behavior near the FSC and spillbays 

2 and 3, which are the two most likely locations for permanent collection entrances in the future. The 

first scenario was the most conservative, including only detections at the small FSC discovery area and 

at spillbays 2 and 3 (figs. 4–6; appendix B). Under this scenario, 61 percent of the steelhead, 33 percent

of the coho salmon, and 88 percent of the Chinook salmon were detected at both the small FSC

discovery area and spillbays 2–3 (table 9). Conversely, 12 percent of the steelhead, 24 percent of the 

coho salmon, and 5 percent of the Chinook salmon were not detected at either location under this 

scenario. The second scenario included detections at the small FSC discovery area along with detections

at spillbays 1–4 (fig. 5). This scenario resulted in marginal increases in detections at both locations for 

steelhead (from 61 to 70 percent) and coho salmon (from 33 to 42 percent), but only a minor increase 

for Chinook salmon (from 88 to 91 percent; table 9). The third scenario included the large FSC

discovery area (fig. 6) area and spillbays 2–3. Results from this scenario were nearly identical to results 

from the second scenario for all species (table 9). The last scenario was the least conservative and used

the large FSC discovery area along with spillbays 1–4. This scenario resulted in the highest proportion 

of tagged fish being detected near both locations for all three species under the various scenarios (80 

percent for steelhead; 54 percent for coho salmon; 93 percent for Chinook salmon; table 9).

Residence Time in Forebay Areas

 To determine where fish resided during the study period, we calculated elapsed residence times 

for individual tagged fish in distinct areas of the forebay. Detections were grouped within nine areas of 

the forebay based on specific antenna locations (table 10) and the entire detection history for each 

tagged fish in the forebay of the dam was considered for this analysis. Chinook salmon generally spent 

the greatest amount of time in the forebay and coho salmon generally spent the least amount of time 

(table 10). Chinook salmon spent the greatest amount of time near the BGS (mean = 1,725.4 mins), 

followed by spillbay 2 entrances (mean = 225.1 mins), and the debris barrier (mean = 134.3 mins; table 

10). Steelhead spent the greatest amount of time near spillbay 3 entrances (mean = 472.2 mins), inside 

spillbay 3 (mean = 91.6 mins), and near spillbay 1 (mean = 79.0 mins). Finally, coho salmon spent the 

greatest amount of time near spillbay 1 (mean = 21.3 mins), followed by inside spillbay 3 (mean = 18.1 

mins), and inside spillbay 2 (mean = 11.3 mins; table 10).

Dam Passage Routes

We found that 62 percent of the steelhead, 84 percent of the coho salmon, and 33 percent of the 

Chinook salmon passed Cowlitz Falls Dam and were detected in the tailrace during our study (table 11). 

Turbine passage was the most frequent passage route used by all species of tagged fish at Cowlitz Falls 

Dam during 2011. Fish that entered the tailrace could only have arrived there by passing through the 

turbines or spillbays, so turbine passage was assigned if tagged fish passed during a period when 

spillbays were not operating. We observed that 40 percent of the steelhead, 52 percent of the coho 

salmon, and 33 percent of the Chinook salmon that entered the dam forebay passed through turbines at 

the dam when the spillbays were not operating (table 11). Passage through spillbays and turbines can 

occur quickly because water moves through these areas at high velocities. Given our criteria for 

requiring at least two valid detections at a given monitoring site, and the burst rate of the transmitters 

that were used for the study (one transmission every 5 s), it was possible for fish to pass through 

turbines or spillbays without being detected. As a result, we grouped spillbay and turbine passage events 

into a single passage category when both turbines and spillbays were operating. We found that 22 

percent of the steelhead and 32 percent of the coho salmon passed through these routes when both 

turbines and spillbays were operating (table 11). 

We also re-examined the detection dataset by removing the criteria for two valid detections at an 

antenna to determine if spillbay and turbine passage routes could be distinguished during these periods. 

For steelhead, we found that 16 percent of the tagged fish passed through turbines compared to 6 

percent through spillbays when both passage routes were available (table 12). For coho salmon, we 

found that 26 percent of the fish passed through turbines and 6 percent passed through spillbays (table 

12). Although this analysis provided the opportunity to re-examine the data using a different set of 

criteria, it was still not possible to assign passage routes with complete certainty, so we urge the reader 

to refer to table 11 when considering passage route data from this study.

Nearly all tagged steelhead (99 percent) and coho salmon (98 percent) passed the dam during the 

study period, whereas nearly one-half (44 percent) of the Chinook salmon remained upstream of 

Cowlitz Falls Dam after their transmitters stopped functioning (table 11). The FSC only collected one 

tagged fish (a Chinook salmon) and almost all other tagged fish that were collected entered through 

collection flumes in spillbay 2. We found that 37 percent of the steelhead, 14 percent of the coho 

salmon, and 23 percent of the Chinook salmon were collected during 2011 (table 11).

Markov Chain Analysis

Approach Data

We examined the movement probabilities for tagged fish during their first encounter with the 

BGS and FSC and found that steelhead, coho salmon, and Chinook salmon responded similarly to these 

devices (tables 13–15). Tagged fish were most likely to first encounter the southern side of the BGS 

(south upstream BGS state; probabilities of 0.378 for steelhead; 0.356 for coho salmon; 0.414 for 

Chinook salmon), followed by the northern side of the BGS (north upstream BGS state; probabilities of 

0.296 for steelhead; 0.218 for coho salmon; 0.323 for Chinook salmon), and the FSC (FSC state; 

probabilities of 0.102 for steelhead; 0.139 for coho salmon; 0.152 for Chinook salmon; tables 13–15). 

Movement probabilities along the BGS showed that fish tended to move along the device, 

however, there also was a tendency for fish to pass under the BGS and move downstream to Cowlitz 

Falls Dam. Guidance along the BGS was defined by movements from the southern side of the BGS to 

the northern side of the BGS, or to the FSC. Tagged fish in the south upstream BGS state had the 

highest probabilities of moving to the north upstream BGS state (0.554 for steelhead; 0.522 for coho 

salmon; 0.462 for Chinook salmon; tables 13–15). However, tagged fish in the south upstream BGS 

state also had moderately high probabilities of moving under the BGS to the south downstream BGS 

state (0.089 for steelhead; 0.196 for coho salmon; 0.369 for Chinook salmon). Probability of movement 

under the BGS were higher from the north upstream BGS state to the north downstream BGS state 

(0.398 for steelhead; 0.322 for coho salmon; 0.437 for Chinook salmon) and all were higher than the 

probability of moving from the north upstream BGS state to the FSC state (0.184 for steelhead; 0.254 

for coho salmon; 0.408 for Chinook salmon; tables 13–15). Steelhead and coho salmon also had

relatively high probabilities of moving to the debris barrier state from the north upstream BGS state

(0.174 for steelhead; 0.136 for coho salmon; tables 13–14). 

Tagged fish that arrived at the FSC (from other states) displayed a range of behavioral patterns 

that included movements to the north shore of the forebay (north FSC gap state), returning upstream 

along the BGS, or moving downstream to the dam. Movement probabilities from the FSC state to the 

north FSC gap state were relatively high for all species (0.307 for steelhead; 0.550 for coho salmon; 

0.258 for Chinook salmon; tables 13–15). However, there were species-specific differences in 

movement patterns from the FSC to the BGS. Juvenile steelhead moved upstream to the north BGS 

states at a relatively high rate (0.242 to the north downstream BGS state; 0.065 to the north upstream

BGS state; 0.307 total; table 13). Chinook salmon were less likely than steelhead to return to the BGS 

(0.183 total; table 15) and juvenile coho salmon had a relatively low probability of moving to the BGS 

(0.083 total; table 14). All three species had relatively high probabilities (0.386 total for steelhead; 0.317 

total for coho salmon; 0.527 total for Chinook salmon) for moving from the FSC state to the dam states 

(debris barrier state; spillbay 1 state; spillbay 2–3 state; tables 13–15). Transition matrices for tagged 

fish movements between individual antenna (ungrouped) locations from the approach dataset are 

presented in appendices C–E of this report. 

Residence Data

Movement probabilities for juvenile steelhead showed that tagged fish moved along the dam and 

returned upstream to the BGS and FSC following arrival at the dam. Tagged steelhead in the debris 

barrier state primarily moved to spillbay 4 (0.265), spillbay 1 (0.191), spillbays 2–3 (0.167), the FSC 

(0.150), and the downstream zones of the north and south BGS states (0.110 and 0.066, respectively; 

table 16). The average number of movements per fish between these states ranged from 2.1 to 4.6, 

which shows that juvenile steelhead made numerous trips between these areas while present in the dam 
14

forebay. Movement probabilities from spillbays 1 and 4 states to the debris barrier state (0.710 and 

0.690, respectively) suggest that tagged steelhead exhibited a strong preference for moving toward the 

center of the dam. Once tagged steelhead were in the spillbay 2–3 state they primarily moved upstream 

to the debris barrier (0.555; 2.9 movements per fish) or passed the dam (0.175 to the fish facility state; 

0.145 to the tailrace state; table 16). Tagged steelhead in the south downstream BGS state tended to pass

under the BGS to the south upstream BGS state (0.395) or guide downstream along the BGS to the 

north downstream BGS state (0.327; table 16). Fish that guided downstream to the north downstream 

BGS state had a strong likelihood of passing under the BGS to the north upstream BGS state (0.435; 7.4 

movements per fish) or moving to the FSC state (0.276; 5.4 movements per fish; table 16). Steelhead 

that arrived at the FSC were never collected through the device (0.000), and preferred to move back 

upstream to the north downstream BGS state (0.496; 6.0 movements per fish) or return downstream to 

the debris barrier state (0.235; 2.8 movements per fish; table 16). 

Tagged coho salmon in the debris barrier state primarily moved to one of the spillbay states and 

had low probabilities of moving back upstream to the BGS or FSC states. Tagged coho salmon 

primarily moved from the debris barrier to spillbay 4 (0.362), spillbays 2–3 (0.258) or spillbay 1 (0.192; 

table 17). Similar to tagged steelhead, juvenile coho salmon that arrived at spillbays 1 and 4 showed a 

strong preference to move toward the center of the dam (debris barrier state; 0.794 and 0.815, 

respectively). Coho salmon that were detected in the spillbay 2–3 state were likely to pass downstream 

into the tailrace (0.449) or move upstream to the debris barrier (0.398). Tagged coho salmon were less 

likely than steelhead to move back upstream to the BGS or FSC. This observation is supported by the 

low probabilities of coho salmon moving from the debris barrier or spillbay states to the BGS or FSC 

zones (probabilities ranging from 0.000 to 0.088; table 17). 

Tagged juvenile Chinook salmon exhibited similar behavior patterns to those of juvenile coho 

salmon during the study period. The probabilities of Chinook salmon moving from the debris barrier to 

the spillbay states (0.444 for the spillbay 2–3 state; 0.247 for the spillbay 4 state; 0.186 for the spillbay 1 

state) were higher than to other states in the forebay (0.000–0.051 for all other states; table 18). Chinook 

salmon had a strong tendency to move toward the center of the dam (to the debris barrier state) from 

spillbays 1 and 4 states (0.736 and 0.849, respectively). Probabilities of Chinook salmon moving from 

the dam to the BGS or FSC were relatively low (0.000–0.145; table 18). Transition matrices for tagged 

fish movements between individual antenna (ungrouped) locations from the residence dataset are 

presented in appendices F–H of this report. 

Discussion

The 2011 radiotelemetry evaluation of juvenile steelhead, coho salmon, and Chinook salmon 

behavior in the forebay of Cowlitz Falls Dam was insightful for understanding fish behavior and 

movement patterns near the BGS and FSC. Results from the study suggest that these devices achieved 

varying degrees of success depending on the variable and species of interest. Tagged fish from all 

species generally were located in the upper 3 m of the water column and dispersed across the forebay 

when they encountered the BGS on their first approach to the dam. Based on this distribution as fish 

approach the dam, the BGS could be useful to intercept fish and guide them towards the proposed 

collector entrance located on the north shore of the forebay, upstream of the dam. The BGS, however, 

was only moderately successful at guiding fish to the FSC during 2011. We found that 50 percent of the 

steelhead, 40 percent of the coho salmon, and 63 percent of the Chinook salmon encountered the FSC 

on their first trip through the forebay and 28–45 percent of those fish did so without guiding along the 

BGS (fig. 16). Analysis of movement probabilities for fish in various states along the BGS 

demonstrated tendencies of tagged fish to move along the upstream and downstream sides of the device, 
15

but these probabilities rarely exceeded 0.500, which indicates that tagged fish were equally likely to 

move into other states. Steelhead and Chinook salmon spent a considerable amount of time in the 

forebay and many Chinook salmon moved upstream of the dam during their forebay residence (table 4). 

This behavior provided additional opportunity for fish to locate the FSC, and 72 percent of the steelhead 

and 92 percent of the Chinook salmon eventually were detected near the device (table 9). Most juvenile 

coho salmon moved downstream after their first trip through the forebay and only 48 percent of the 

tagged coho salmon juveniles that arrived in the forebay of Cowlitz Falls Dam were detected near the 

FSC (table 9). 

The interpretation of BGS guidance results during 2011 are complicated by the subjective nature

of the FSC boundary definitions and the long-term vision for a FSC that will use substantially more 

flow than the prototype collector used during this study. High collection rates through the FSC were not 

required for the FSC/BGS complex to be considered successful during 2011. The goal for 2011 was 

high FSC encounter rates rather than high capture rates because the FSC used during this evaluation was 

considered temporary. In order to estimate fish encounters with the FSC, we had to subjectively define 

the spatial extent of the device based on underwater antennas positioned on the BGS and FSC. We 

chose a conservative approach and used underwater antennas mounted on the FSC, and on the first two 

BGS panels upstream of the FSC, to define the FSC boundaries we used to estimate FSC discovery rates 

and BGS guidance (that is, FSC encounter rate = 50 percent for steelhead, 40 percent for coho salmon, 

63 percent for Chinook salmon; previous paragraph). However, using an expanded definition of the FSC 

where additional BGS panels (six panels upstream of the BGS) were included, FSC encounter rates

increased by an additional 15–24 percent (figs. 16–17). Similarly, FSC and spillbay 2–3 encounter rates 

varied substantially based on the antenna combinations used to define these areas in table 9. The use of 

discovery rates estimated in 2011 to estimate collection success in the future is complicated because the 

proposed FSC will operate using approximately 25 times more water than the FSC used during 2011 

(that is, 500 ft3

/s versus <20 ft3/s). Given this disparity, it is difficult to determine how much BGS 

guidance would be required for juvenile salmon to encounter the FSC. Based on these uncertainties, we 

chose to calculate movement probabilities between distinct areas of the forebay to understand fish 

movement patterns. 

The varied results for BGS guidance and FSC encounter rates support the idea of using a dambased collection option simultaneously with a BGS/FSC complex to maximize encounter rates for 

juvenile salmonids at collection entrances in the forebay of Cowlitz Falls Dam. Radio-tagged fish were 

dispersed across the dam face on their initial encounter (table 7) but movement probabilities (0.690–

0.841; tables 16–18) showed a strong tendency for all species to move from the outer edges of the dam 

(spillbays 1 and 4) to the center of the dam (the debris barrier). This behavior would be ideal for 

maximizing encounter rates of juvenile salmon at one or more collection devices, such as a weir box, 

located in spillbays 2 or 3. However, the debris barrier may limit spillbays 2 and 3 encounter rates as 

demonstrated by the relatively low probabilities of fish moving from the debris barrier to spillbays 2 and 

3 (0.167 for steelhead; 0.258 for coho salmon; 0.444 for Chinook salmon; tables 16–18). Additionally, 

we observed that 15 steelhead, 18 coho salmon, and 19 Chinook salmon moved from the debris barrier 

to the tailrace, which is consistent with turbine entrainment for fish that sound beneath the debris 

barrier, which extends 2.7 m below the surface of the forebay (tables 16–18). Regardless of these 

effects, we found that 76 percent of the steelhead, 61 percent of the coho salmon, and 92 percent of the 

Chinook salmon were detected near entrances to spillbays 2 and 3, where weir box deployments have 
16

been proposed (table 9). We also examined the proportion of tagged fish that encountered at least one of 

the proposed collection locations (the FSC and spillbays 2 and 3) and found that 88 percent of the 

steelhead, 76 percent of the coho salmon, and 95 percent of the Chinook salmon were detected in at 

least one of these areas (table 9). 

Past studies have shown that juvenile salmonids will guide along a BGS, when present in a dam 

forebay, but these studies also have shown that tagged fish will pass around or under the device, which 

has limited the effectiveness of these structures. Large BGS’s have been deployed and tested at Lower 

Granite Dam on the Snake River, and at Bonneville Dam on the Columbia River where evaluations 

showed that 60–80 percent of the tagged fish were guided by these devices (Adams and others, 2001; 

Faber and others, 2010). At both locations, these devices were abandoned because they failed to guide 

enough fish to justify the expense required to operate and maintain these systems during periods when 

juvenile salmonids were passing the dams. Similarly, the BGS at Cowlitz Falls Dam has been shown to 

provide guidance for a portion of the fish that were studied during 2010 (HDR, 2010) and 2011, but the 

future of the BGS will depend on how it performs when the new FSC is in place and operating. 

River flows affect collection of juvenile salmon at Cowlitz Falls Dam, so it is important to

review fish behavior during 2011 in the context of the observed flow conditions. Juvenile steelhead and 

coho salmon out-migrate primarily during April–June each year when runoff conditions commonly 

result in high-flow periods at Cowlitz Falls Dam. Coho salmon are affected by high-flow periods as 

evidenced by the large decreases in collection efficiencies observed when river flows exceed 6,000 ft3

/s 

(John Serl, Washington Department of Fish and Wildlife, oral commun., 2011). Mean daily river flows 

exceeded 6,000 ft3

/s on 64 d (46 percent) during the collection season (April 15–August 31) in 2011, 

which is well above the 40 d average observed during 2000–2011. River flows that exceed 10,000 ft3

/s 

require spill operations at Cowlitz Falls Dam that provide an additional passage route that lacks a 

collection opportunity. Spill conditions were observed during 17 d (12 percent) in 2011 as compared to 

the 11 d average observed during the past decade. Given the higher than normal spring flows in 2011, 

the BGS/FSC likely guided fewer fish during 2011 than would be expected during years when spring 

flows are lower. For example, we found that 37 percent of the radio-tagged steelhead, and 14 percent of 

the radio-tagged coho salmon were collected during 2011, compared to 44 and 64 percent, respectively, 

during 2007, when river flows exceeded 6,000 ft3/s on 22 d (16 percent). Conversely, higher than 

normal river flows during the Chinook salmon outmigration period (July–August) may have resulted in 

elevated performance of the BGS/FSC. River flows lower than about 1,800 ft3

/s result in no-flow 

periods at Cowlitz Falls Dam when the turbines are not operated. Low-flow periods during summer 

months typically are associated with increasing water temperatures as well, and the combination of noflow conditions at the dam in conjunction with increasing water temperatures likely leads to decreasing 

collection efficiencies traditionally observed during August each year (John Serl, Washington 

Department of Fish and Wildlife, oral commun., 2011). During 2011, mean daily river flows fell below 

1,800 ft3

/s on 1 d during the collection season, which is well below the long-term average of 27 d. 

Additionally, we found that 44 percent of the juvenile Chinook salmon did not pass Cowlitz Falls Dam 

while their transmitters were operating and this is a significant percentage in light of the long-term 

(about 2 months) operating life of the transmitters used during this study. Tagged fish were observed 

moving throughout the dam forebay and Lake Scanewa during this period so mortality does not appear 

to be a causal factor for this failure to pass the dam. Given this observation, a substantial number of 

juvenile Chinook salmon likely pass Cowlitz Falls Dam during fall or winter months because yearling 

Chinook salmon are rarely captured at the fish facility (John Serl, Washington Department of Fish and 

Wildlife, oral commun., 2011). 
17

In summary, this evaluation was insightful for understanding juvenile salmon behavior near the 

BGS and for estimating proportions of tagged fish that were detected near the FSC and spillbays 2 and 

3. Results from the study demonstrated that tagged fish guided along the BGS but also passed under the 

device readily, and moved downstream to the dam. Our use of the Markov chain analysis to describe 

probabilities of movement provided additional information that was insightful. However, these 

estimates were obtained during a single fish collection season, which included periods of atypical flow 

and confidence intervals for the probability estimates, in most cases, were fairly large (>20 percent; 

tables 13–18; appendices C–H). Encounter rates of the FSC and spillbays 2 and 3 were estimated, but 

these estimates varied depending on the spatial boundaries that were used to define the zones. The 

effects of a future FSC, which will use substantially higher flows than the prototype FSC, on BGS 

effectiveness and FSC discovery rates is unclear.

Appendix F. Movement Probabilities for Radio-Tagged Steelhead between Individual Antennas from the

Residence Dataset at Cowlitz Falls Dam during 2011. —Continued 

[Each cell contains five rows of data including the probability of movement (row 1), the 95-percent confidence interval for the probability estimate (row 2) the 

number of movements (row 3), the number of fish that made movements (row 4), and the average number of movements per fish (row 5)]

Appendix G. Movement Probabilities for Radio-Tagged Coho Salmon between Individual Antennas 

from the Residence Dataset at Cowlitz Falls Dam during 2011.—Continued

[Each cell contains five rows of data including the probability of movement (row 1), the 95-percent confidence interval for the probability estimate (row 2) the 

number of movements (row 3), the number of fish that made movements (row 4), and the average number of movements per fish (row 5)]
