| Description: | Technical Report Abstract: This report identifies factors that alter the relative abundance of tailwater fishes. Specifically, the objectives of this s tudy were to determine the significance of fish recruitment from the reservoir into the tailwater, determine which species are recruited from the reservoir, identify conditions in the tailwater that foster the concentration of fish, identify the season of recruitment, and describe the direction and season of movement of tailwater fishes. To meet these objectives, fish were intensively sampled, marked, and recaptured in the immediate tailwater of Barren River Lake, Ky., for 1 year. Analyses of the resulting data indicated that the reservoir may be the source of recruitment for the most abundant fish in the tailwater of deep-release, flood control reservoirs; the passage of fish from the reservoir into the tailwater exhibits pronounced seasonality; the seasonality of fish passage can be related to conditions in the reservoir relative to the behavior of certain common fishes; and project operation can have substantial effects on the tailwater fishery by altering conditions that foster the movement of reservoir fish into the tailwater. |
