Floating Screen Project to Collect Juvenile Fish in Detroit Reservoir
Bremerton–based naval architecture and marine engineering firm Art Anderson Associates is working with the U.S. Army Corps of Engineers (USACE) in Portland to provide architectural and engineering services for the design of a downstream fish passage floating screen structure (FSS) in the Detroit Reservoir. The FSS has an estimated maximum cubic feet per second (cfs) between 1,000 and 4,500 cfs and is intended to attract and collect juvenile fish in the reservoir and expected to increase outmigration.
The USACE Portland District (CENWP) is simultaneously designing a selective withdrawal structure (SWS) with a weir box to provide temperature control in the North Santiam River, intending for the flow to pass through the FSS, screen out the fish, pass through the SWS and ultimately pass through the turbines and further down river. The fish that were separated from the flow and collected will be passed further downstream. The project is one of seven floating fish collectors in the Pacific Northwest.
