CDP - Cushman Dam Project

Status:   Active - Non-Operational
Site Type: Juvenile Fish Bypass Facility  |  Organization: Tacoma Public Utilities
General Operational Period: Seasonally
Start Date: 5/14/2015 12:00 AM

The Cushman Hydroelectric Project consists of two high-head dams on the North Fork Skokomish River. Cushman Dam #1 is the upstream most dam and impounds Lake Cushman. Cushman Dam #2 is about two miles downstream and impounds Lake Kokanee. Initial configuration included 2 sets of PIT tag readers: one associated with a juvenile fish passage floating surface collector at Cushman Dam #1 and one in the Cushman Dam fish facility at Cushman Dam #2 following fish handling. In 2017, two antennas were installed in the net transition structure upstream of the floating surface collector. Out migrating smolts are collected at the floating surface collector and transported to the fish facilities from where they are released downstream of Cushman Dam #2. There is no fish passage between the two dams other than through the floating surface collector at Cushman Dam #1. Returning adults are also scanned at the fish facility at Cushman Dam #2.
