ALP 3

Contents
For trial 1 through 10, no LMB were found alive immediately after sleeve valve passage. For the
10 replicates performed at the reservoir elevation of 6846 ft, 993 live 0 -plus largemouth bass (55
mm) were injected into the discharge pipe. No LMB were found alive immediately after sleeve
valve passage (figure 38) and none were found to be still breathing but motionless. Immediate
mortality for the 55 mm LMB was 100 percent at an estimated reservoir pressure of 58 psi.

At the reservoir elegy ljQrl of684F,ft, a total of 10 trials were performed using 100 live fathead
minnow (mean T1,110 mm, mean height 8.5 mm), per trial. Total' length FHM measurements
ranged from 36 to 72 mto., Two F.HIy1 from trial's escaped the injection process and one FHM
escaped fr ©m finial 7. Each pplie was injected Into the discharge pipe immediately before the

58 usi.
For trial 1, six FHM were'found alivehijthe entrainment nets after sleeve valve passage. Two
FHM (53 and,59 mm) died at4,hrs, two)~HM (45 and 49 mm) died at 72 hrs. Two FHM (42
and 49 mm) survived beyond 96 tars and were in good condition.
For trial 2, two FHM were found alive in the entrainment nets immediately after sleeve valve
passage where one FHTu1',died (4 1 mm) at 24 hrs and the other FHM (42 mm) survived beyond
96 hrs but was hemorrhaging around right eye.
For trial 3, six FHM were found alive in the entrainment nets. Five FHM (42, 46, 49, 50 and 69
mm) died at 24 hrs. The remaining live FHM (40 mm) was still breathing at 96 hrs but had
internal hemorrhaging symptoms and bulging eyes and was motionless.
Trials 4 and 5 had no FHM survivors immediately after sleeve valve passage.
