The study addresses questions regarding unscreened diversions and assesses their threats to juvenile Chinook salmon, with a focus on hydraulic conditions around diversion intakes. The experiments were conducted in a large hydraulic flume at the J. Amorocho Hydraulics Laboratory. Hydraulic fields were evaluated with regard to diversion intake size, diversion rate, river flow conditions and various fish deterring devices. The entrainment rate of juvenile Chinook salmon at unscreened diversions affected by varying hydraulic conditions was evaluated, as was the entrainment rate associated with various fish deterring devices.
