Description:

As part of the continuing evaluation of extended-length screens at The Dalles Dam, orifice passage efficiency (OPE) tests using a mark/recapture method were conducted during spring and summer 1995 in Turbine Units 5 (west end of powerhouse), 12 (middle), and 17 (east end). In addition, descaling and the horizontal distribution of juvenile salmonids were monitored in these units, and dip-basket efficiency and gatewell mortality tests were conducted.
