Title: Washington Department of Fish and Wildlife Fish Program Hatcheries Division: Ford Hatchery, Annual Report 2001-2002.

Abstract

The Washington Department of Fish and Wildlife implemented the Banks Lake Fishery Evaluation Project (BLFEP) in September 2001 with funds from the Bonneville Power Administration. The first year of the BLFEP was used to gather historic information, establish methods and protocols, collect limnology data, and conduct the first seasonal fish surveys. Water quality parameters were collected monthly from February to May and bi-monthly from June to August. Banks Lake water temperatures began to increase in April and stratification was apparent by June at all 3 limnology collection sites. By late August, the thermocline had dropped to nearly 20 m deep, with 19-20 C temperatures throughout the epilimnion. Dissolved oxygen levels were generally above 10 mg/L until mid summer when dissolved oxygen dropped near or below 5 mg/L below 20-m deep. Secchi depths ranged from 3-10 m and varied by location and date. Nearshore and offshore fish surveys were conducted in May and July using boat electrofishing, fyke net, gill net, and hydroacoustic surveys. Smallmouth bass Micropterous dolomieui (24%) and lake whitefish Coregonus clupeaformis (20%) dominated the nearshore species composition in May; however, by July yellow perch Perca flavescens (26%) were the second most common species to smallmouth bass (30%). Lakemore » whitefish dominated the offshore catch during May (72%) and July (90%). The May hydroacoustic survey revealed highest densities of fish in the upper 1/3 of the water column in the mid- to northern sections of the reservoir near Steamboat Rock. In the future, data from seasonal surveys will be used to identify potential factors that may limit the production and harvest of kokanee, rainbow trout, and various spiny-rayed fishes in Banks Lake. The limiting factors that will be examined consist of: abiotic factors including water temperature, dissolved oxygen levels, habitat, exploitation and entrainment; and biotic factors including food limitation and predation. The BLFEP will also evaluate the success of several rearing and stocking strategies for hatchery kokanee in Banks Lake.« less
