Floating surface collector for fish on North Fork Lewis River, WA
Floating surface collector for fish on North Fork Lewis River, WAA floating surface collector in the Swift Reservoir on the North Fork Lewis River, WA. A floating surface collector attracts and collects juvenile fish before they pass through a dam so they can be held for transport past the dam via barge or truck.
