Oregon: Round Butte Dam, Deschutes River

Portland General Electric and the Confederated Tribes of the Warm Springs, co-owners of Round Butte Dam, completed construction of the 270 foot tall Selective Water Withdrawal Structure (SWW) upstream of Round Butte Dam in winter 2009. The SWW redirects currents in the reservoir upstream of the dam and collects fish either for transport below the facility or release back into the reservoir. Biomark constructed a PIT-tag detection system to monitor the 24 in. bypass between the collection bays and the fish transfer facility (FTF). The first PIT-tagged fish collected were detected in March 2010. Additionally, Biomark designed and constructed two PIT-tag workstations for the FTF that include: custom antennas, digitizing tablet, load cell, and re-circulating anesthetic sinks.
