Two horizontal traveling screens were designed and operated for 2 years at the Carson National Fish Hatchery, Carson, Wash.  Deflection efficiencies were 100 percent in 37 tests of over 11,000 juvenile coho Oncorhynchus kisutch and Chinook salmon O. tshawytscha.  The screens demonstrated their potential capacity to divert young salmon moving downstream.
