Fishing has been opened on most lakes within the district on a year-round basis. Lake rehabilitation was undertaken in two areas. During the summer of 1958 and the winter of 1958-59 a detailed creel census was con- ducted on Georgetown Lake. The purpose of the study was to get good estimates of total fish taken and the fishing effort exerted on this popular lake. This census will be repeated at two-year intervals for at least six years. Re- sulting information will provide the basis for maintaining the highest quality fishing possible in Georgetown Lake. Estimates from the first year's study showed that 25,000 fishermen caught 47,000 game fish during the summer season. During the winter season 18,000 ang- lers took an additional 70,000 game fish. By weight, these fish totaled 41 tons, or almost thirty pounds of game fish per acre from this productive mountain Bob Averett, pollution control biologist, sets up field equipment while working on a water problem. ( Photo by Tom Smith-) Two major pollution problems confronted the western fisheries district during the past biennium. Both were on the Clark Fork River —one in 1958 from about 10 to 60 miles west of Missoula, and the other in early 1960 from the river's headwaters to an as yet unknown distance downstream. Immediate investiga- tion of both problems in cooperation with pol- lution control authorities led to the immediate discovery of pollution sources and their sub- sequent abatement. Follow-up studies on the 1958 problem, associated with the pollution control project, have provided estimates that game fish were removed from 25 miles of the Clark Fork. An appraisal of recovery was also established. A similar investigation of the 1960 problem area is scheduled. During early summer of 1959 the U. S. Forest Service sprayed DDT for
