Abstrakt: Fish populations in the Blenheim-Gilboa (B-G) pumped storage reservoirs in the Catskills in New York have been studied since the reservoirs were completed in 1973. The reservoir populations developed entirely from the fishes present in Schoharie Creek and from emigrants from Schoharie Reservoir located 2.5 miles upstream. The fish populations of Schoharie Creek were composed primarily of pumpkinseed, rock bass, white sucker, and brown bullhead. Thirty-four species of fish have been collected in the reservoirs. The more common species in the upper reservoir included yellow perch, pumpkinseed and redbreast sunfish. In the lower reservoir, white sucker, carp, brown bullhead and pumpkinseed were common. Differences between the populations in the two reservoirs are attributed to differences in substrate and to loss of shallow water caused by water level fluctuations. Management techniques employed to date include removal of rough fish to enhance gamefish, construction of constant level ponds for sunfish spawning, and stocking of trout for trout fishing. A fourth technique which appears attractive is the stocking of young walleye fry to enhance the walleye fishery.
