Diel Distribution of Entrained Specimens

The diel distribution of larval and juvenile fish was recorded as part of the entrainment 

abundance study. The majority (99%) of these fish were larvae. A detailed summary of 

entrainment densities is presented in Table 4. A peak density of 171 specimens per m3 was 

observed during the night sampling event of June 13, 2005. The majority of larvae collected on 

this date (66%) were identified as freshwater drum. Mean monthly densities of larval and 

juvenile fish, are presented in Figure 1.

Long-Term Survival Studies

A total of six long-term survival studies were conducted over the duration of the impingement 

abundance study:

The first long-term survival study was initiated on August 24, 2005. The holding tanks for this 

study were split into two sections with wire mesh to create 4 separate holding areas.1 A total of

345 fish (12 species) were collected and evaluated for this study. Immediately upon collection, 

199 fish (58%) were categorized as dead and 146 fish (42%) were categorized as live. Of the 

146 live fish evaluated for long-term survival, only 4 fish (3%) survived 48-hours after being 

impinged at Bay Shore. Details of this survival study are summarized in Table 5.

The second long-term survival study was initiated on October 30, 2005. A total of 1,324 fish (11 

species) were collected and evaluated for this study. Immediately upon collection, 721 fish 

(54%) were categorized as dead and 603 fish (46%) were categorized as live. These fish were 

split among 3 different holding tanks. Of the 603 live fish evaluated for long-term survival, a 

total of 29 fish (5%) survived 48-hours after being impinged at Bay Shore. Details of this 

survival study are summarized in Table 6.

The third long-term survival study was initiated on February 24, 2006. A total of 250 emerald 

shiners were collected and evaluated for this study. Immediately upon collection, 90 fish (36%) 

were categorized as dead and 160 fish (64%) were categorized as live. These fish were split 

among 5 different holding tanks. Of the 160 live fish evaluated for long-term survival, a total of 

53 fish (33%) survived 48-hours after being impinged at Bay Shore. Details of this survival 

study are summarized in Table 7.

The fourth long-term survival study was initiated on May 4, 2006. A total of 250 emerald shiners 

were collected and evaluated for this study. Immediately upon collection, 37 fish (15%) were 

categorized as dead and 213 fish (85%) were categorized as live. These fish were split among 5 

different holding tanks. Of the 213 live fish evaluated for long-term survival, a total of 78 fish 

(37%) survived 48-hours after being impinged at Bay Shore. Details of this survival study are 

summarized in Table 8.

The fifth long-term survival study was initiated on November 15, 2006. A total of 105 live white 

perch were collected and evaluated for this study. These fish were split among 5 different 

holding tanks (15-25 fish per tank). A total of 31 fish (30%) survived 48-hours after being 

impinged at Bay Shore. Details of this survival study are summarized in Table 9.

The sixth long-term survival study was initiated on November 29, 2006. A total of 250 emerald 

shiners were collected and evaluated for this study. Immediately upon collection, 90 fish (36%) 

were categorized as dead and 160 fish (64%) were categorized as live. These fish were split 

among 5 different holding tanks. Of the 160 live fish evaluated for long-term survival, a total of 

53 fish (33%) survived 48-hours after being impinged at Bay Shore. Details of this survival 

study are summarized in Table 10.

This approach was discontinued as it was not possible to prevent fish from swimming through the mesh dividers 

into a different holding area.

Entrainment Data Analysis

Entrainment data were converted to a 24-hour collection period by adjusting for sample volumes 

and the corresponding volume through the screenhouse.2 To calculate the base density of 

entrained eggs/larval fish (e-base), the number entrained during each sampling period was 

divided by the corresponding sampling volume. This is expressed as:

e-base = Ni/ Vi

where:

e-base = Base entrainment density (#/m3)

Ni = Total number of eggs/larval fish entrained (10 daily samples) 

Vi = Total volume of water filtered for 10 daily samples (m3). 

Base entrainment densities were multiplied by daily flow volumes to obtain entrainment 

estimates for each day. Sample calculations for entrained fish eggs are presented in Table 11. 

Monthly entrainment estimates were calculated using the following formula:

Estimated Number = Monthly Number of Organisms x Total Monthly Flow

Entrained per Month Monthly Sample Volume

Impingement Data Analysis

Impingement data were converted to a 24-hour collection period by adjusting for sample 

duration (e.g. 24/1) and the number of active traveling screens (e.g. 9/4).3 Sample calculations 

are presented in Table 12. Monthly impingement estimates were calculated using the following 

formula:

Estimated Number = Monthly Number of Fish x Total Monthly Flow

Impinged per Month Monthly Sample Volume

 

2 Daily cooling water flow volumes (MGD) were obtained from the Monthly Operating Report (MOR) for 

Bay Shore and are summarized in Table 1. 

3 While there are nine (9) functional traveling screens at Bay Shore, two (2) screens are only turned 

infrequently (1⁄4-hour to 1⁄2-hour per day). The traveling screen adjustment for this assessment was

estimated conservatively and assumed that all nine (9) screens were active.
