CFD - Cowlitz Falls Dam

Status: Active - Operational

Site Type: Juvenile Fish Bypass Facility | Organization: Tacoma Public Utilities

General Operational Period: Seasonally
Start Date: 4/16/2013 12:00 AM

Upstream most dam on Cowlitz River. As of 2014 fish facilities include 3 sets of PIT tag readers. One associated with each of the spillway #2 and #3 flumes, and one downstream of the Cowlitz Falls Fish Facility following fish handling. In April 2017, 3 antennas were installed in the Cowlitz Falls North Shore Collector, and 2 sets of 2 antennas each were installed downstream of the separator to support sort by code operations. In 2023, transceiver 20 (previously used for antennas 20-26) was replaced and updated to four IS1001 standalone transceivers. Each new transceiver is associated with one exit route antenna. Antenna 31 is for the hopper. Antenna 32 is for the fry raceway. Antenna 33 is for the smolt raceways. Antenna 34 is for a new location, the transport tank.
