ALP 3

Contents
There were no survivors for trial 3.
For trial 4, two white suckers were found alive immediately after sleeve valve passage, one in the
entrainment nets and one in the spillway. One died at 24 hrs (47 mm) and one survived beyond
96 hrs (47 mm) after sleeve valve passage.
For trial 5, one white sucker (51 mm) was found alive in the spillway and survived beyond 96
hrs after sleeve valve passage.
There were no survivors for trial 6.
For trial 7, one white sucker (54 mm) was found alive in,'#he entrainment nets and survived
beyond 96 hrs after sleeve valve passage.
For the 7 replicates performed at the reservoir elevation of 6795 ft, 680 live 0 -plus white suckers
(60 mm mean TL) were injected into the discharge pipe. Six white suckers were alive
immediately after sleeve valve passage (0.882 percent) ranging between 0 and f sh per trial
(figure 22). Five survived beyond 96 hrs (0.735 percent) aid ranged between 0 and 1 fish per
trial (figure 23).

White Sucker (110 mm mean TL)
A total of six trials were performed using 100 1 -plus white suckers (mean TL 110 mm, mean
width 13.7 mm) per trial except for trial 1 where 75 fish were used, no fish escaped the injection
process. Total length measurements of the 1 -plus white suckers ranged from 85 to 127 mm. The
trials were performed concurrently with the smaller 0 -plus white suckers. Each replicate was
injected into the discharge pipe upstream of the sleeve valve to test the effectiveness to eliminate
1 -plus white sucker survival at a pressure of approximately 36 psi.
