Creel census studies were conducted at Twin Lakes, Colo. from 1972 to 1979 to characterize the fishery, and to provide a basis for the evaluation of potential impacts upon the fishery resulting from the construction and operation of the Mt. Elbert Pumped-Storage Powerplant located on the lower lake. In this report, creel census data are presented for the period December 1976 to September 1979. Creel census has resulted in characterization of the Twin Lakes fishery with a precision adequate for analyses of pumped-storage effects upon the major components of the fishery. Potential powerplant impacts, such as increased mortality to rainbow trout, daily and seasonal water-level fluctuations, and shoreline turbidity may have adverse effects on the Twin Lakes shore fishery for rainbow trout. Large-scale impacts probably will be necessary to demonstrate effects upon the boat fishery and the lake trout harvest.
