KPFF is providing detailed design for this intake fish screen and fish passage. KPFF previously provided topographic surveying and a preliminary engineering study for this new 40 cfs hatchery intake fish screen and juvenile fish ladder including upland and detail river mapping. The river channel was mapped beyond the immediate design area using cross sectional data later used for Hec-Ras modeling. Current ongoing evaluation includes investigation and hydraulic analysis of hatchery intake site, development of various options for upgrades to existing fish screens and bypass facilities, design of new juvenile vertical slot fish ladder to provide passage for resident and returning hatchery adult anadromous fish, design of a new velocity barrier structure within the stream corridor to direct fish up the ladder and development of new fish trapping and sorting facilities.
