Since the late 1980's, Snake River sockeye Oncorhynchus nerka adults have only returned to Redfish Lake, one of five lakes in the Sawtooth Basin which historically reared sockeye. 1997 project objectives included (1) characterization of the limnology of Sawtooth Valley lakes; (2) fertilization of Redfish, Pettit, and Alturas lakes; (3) O.nerka lake population surveys; (4) estimation of kokanee escapement and fry production in Alturas Lake Creek, Stanley Lake Creek, and Fishhook Creek; (5) reduce the number of spawning kokanee in Fishook Creek; (6) evaluate hatchery rainbow trout overwinter survival and potential competition and predation interactions with O.nerka in Pettit Lake; (7) assess predation from bull trout Salvelinus malma, brook trout S.fontinalis, and northern squawfish Ptychocheilus oregonsis on lentic O.nerka; (8) establish screw tap and weir sites to monitor smolt emigration.
