ALP 3

Contents
For the 6 replicates performed at the reservoir elevation of 6795 ft, 575 live white suckers (110
mm) were injected into the discharge pipe. No white suckers were found alive in any of the six
trials immediately after sleeve valve passage (figure 24 and 25) in either the entrainment nets or
in the spillway area.

incidental handling motfalrtx at 0 hrs for the 3 test species or at 96 hrs for either the bluegill or
fathead minnows. At 961ug after handling and holding, a total of 7 rainbow trout eggs died for a
mean survival rate of 99.8 percent (table 4).
