Description

The Confederated Tribes of the Umatilla Indian Reservation (CTUIR) and Oregon Department of Fish and Wildlife (ODFW) are cooperating in a joint effort to enhance steelhead and re-establish salmon runs in the Umatilla River Basin. Bonifer Pond, Minthorn Springs and Imeques C-mem-ini-kem acclimation facilities are operated for acclimation and release of juvenile summer steelhead (Oncorhynchus mykiss), fall and spring chinook salmon (O. tshawytscha) and coho salmon (O, kisutch). Minthorn is also used for holding and spawning summer steelhead, fall chinook and coho salmon. In the spring of 1994, juvenile summer steelhead were acclimated at Bonifer and Minthorn. At Imeques C-mem-ini-kem, juvenile spring chinook were acclimated in the spring and fall. A total of 92 unmarked and 42 marked summer steelhead were collected for broodstock at Three Mile Dam from October 1, 1993 through May 2, 1994 and held at Minthorn. An estimated 234,432 green eggs were taken from 48 females. The eggs were transferred to Irrigon Hatchery for incubation and early rearing. Fingerlings were transferred to Umatilla Hatchery for final rearing and release into the Umatilla River in 1995. Fall chinook and coho salmon broodstock were not collected in 1994. Coded-wire tag recovery information was accessed to determine the contribution of Umatilla River releases to ocean, Columbia River and Umatilla River fisheries. Total estimated juvenile adult survival rates are detailed in this document.
