An angler harvest survey, consisting of two independent surveys, was conducted on Lake Francis Case, South Dakota, from May through October 1981, and April through October 1982. An aerial angler count was used to estimate angle pressure, and an angler interview survey was used to estimate catch rate. In 1981, a section of Lake Francis Case in the vicinity of the Gregory County Pump Storage Project (Zone 2) was surveyed. IN 1982, the survey was expanded to include the entire reservoir (additional Zones 1 and 3). Estimated fishing pressure for Zone 2 in 1981 was 188,631 angler-hours and in 1982 it was 31,555 fish. Total 1982 harvest for the entire reservoir was 136,150 fish. The overall catch rate for Zone 2 in 1981 was 0.31 fish per angler-hour and in 1982 it was 0.29 fish per angler-hour. The catch rate for all zones combined in 1982 was 0.27 fish per angler-hour.
