effectiveness of the sleeve valve to eliminate fish embryo survival at a pressure of approximately
62 psi.
For the 10 replicates performed at the reservoir elevation of 6855 ft, 9,991 live RBT eggs were
injected into the discharge pipe. For all 10 trials, RBT eggs were found alive in the entrainment
nets and in the spillway area. A total of 2,048 RBT eggs were found alive immediately after
sleeve valve passage and live recoveries ranged between 94 and 314 eggs (figure 45). Rainbow
trout egg survival at 96 hrs after sleeve valve passage ranged between 37 and 201 live eggs
(figure 46). Immediate RBT egg survival for all 10 trials was.203 percent and averaged 11.12
percent survival after 96 hrs.

Three sets of 100 1 -plus largemouth bass (mean TL 65 mm, mean height 13.8 mm), 200 fathead
minnow (mean TL 40 mm, moan,height 7.2 mm), and three sets of 1,000 rainbow trout eggs
were handled and introduced info a simulated insertion port and receiving pipe using the same
methods as the test'ftsh ;and e'to discern the extent of incidental handling mortality. The fish
were measured (except -RBT eggs), netted, and handled as test fish were and held in the
same containers and in the ame water quality conditions. There was no incidental handling
mortalities at 0 hrs for the LMB but there were 2 mortalities for the FHM and RBT eggs.
However, after 96 hrs 3 LMB died (99 percent survival), 7 RBT eggs died (99.77 percent
survival), and 29 fathead minnows died (95.17 percent survival) (table 11).
