Abstract
Turbine intake gatewells at Ice Harbor Dam on the Snake River were evaluated for their utility as collection areas of juvenile salmonids. The investigation took place from 1964 through 1966; results indicated that gatewell collecting is economical and efficient. One 3‐man crew, in 1964, did the sampling; depending on water flow, the collections represented 2 to 6% of the total population. The sampling rate in the gatewells will enable a high degree of confidence to be placed on measurements of timing, migration rates, survival, and relative magnitude of the seaward migrations.Keywords
