The Lewis River Hydroelectric Project is designed to meet the electrical needs of customers while operating two fish passage projects to support and improve the production of wild migratory fish. Surrounded by forest, heavy rains wash large wooden debris into the river system, clogging the fish collection system and leading to costly shutdowns.

The Trash Hunter aids in fish migration and population growth by removing floating debris before the dam, intake, and fish collectors; ensuring they can move freely and safely through. The debris removal also helps prevent clogging and equipment damage, ensuring the efficient operation of the facility.
