Downstream Passage
▪ Entrainment
▪ Ski-jump spillway
▪ “Gulpers”
Upstream trap - 1957
Ski-jump spillway - 1955
Downstream Passage
LB “gulper” installed 1958
▪ Tested two years
▪ 90-cfs flow
▪ 36’ x 68’
▪ Bypass pipeline to tailrace

Net Development
▪ Hydroacoustics – fish
deeper than baffle
▪ Focus on nets since 1985
key to success at Baker
▪ Well-suited to nets
Stage I – 1” mesh x 100’ depth
Stage II – 1/4” mesh x 100’ depth (4 deep panels)
Stage III – 3/32” & 1/4” mesh, full depth, shore-toshore, pneumatic control, intermediate floats

Non-Migrant Effect
No consideration –
need to capture 95 fish
reservoir mortality
~3% (1-6%)
100 “migrant” test
fish released
Migrant impact –
need to capture 83 fish
reservoir residence
10-30%
