Approximately 701 game fish, including 120 cutthroat trout Oncorhynchus clarki, two rainbow trout O. mykiss, 175 brown trout Salmo trutta and 256 lake trout Salvelinus namaycush, were salvaged from the Palisades Dam stilling basin and released to the South Fork Snake River immediately below the stilling basin. The number and size distribution of lake trout sampled again confirm this species is reproducing naturally in Palisades Reservoir. Mud Lake was stocked with 50,000 Lahontan cutthroat trout O. clarki henshawi in October and with a total of 46,000 tiger muskies Esox lucius x Esox masquinongy in two stockings during August and September. Sixteen mountain lakes were stocked with a total of 14,000 cutthroat trout, 2,000 rainbow trout and 4,000 Arctic grayling Thymallus arcticus in September 1997. All fish were reared at Mackay and Ashton hatcheries and were stocked by Idaho Department of Fish and Game (Department) personnel and volunteers via foot, motorcycle and horseback. Catchable rainbow trout were provided to two private pond owners at their request for the purpose of supporting public youth and providing fishing opportunities for the developmentally challenged. INTRODUCTION In addition to routine hatchery fish stocking activities, a variety of fish population management situations require regional attention by fisheries management personnel. Annual maintenance of the Palisades Dam spill gates requires the stilling basin to be drained, stranding hundreds of fish. The Idaho Department of Fish and Game (Department), US Bureau of Reclamation and volunteers routinely salvage and move stranded game fish to the main river channel. Specialty fish stocking and mountain lake stocking projects require organized efforts by regional, reservist and volunteer personnel. In 1997, Mud Lake and 16 mountain lakes received hatchery fish supplementation to support public sport fishing opportunity. We also provided hatchery catchable rainbow trout Oncorhynchus mykiss to two private pond owners who granted public access to local youth and educational groups for angling outings.
