Co-op Lake is situated approximately 24 km east of Burns Lake, B.C. It is a small lake of approximately 31 ha with a maximum depth of 10.3 m. The lake has good year round access, and supports both a winter and a summer fishery for stocked brook trout. this report evaluates the Fishery based on historic and 1984 survey results. The fish in Co-op Lake all seem to be healthy. The average size has not changed much from the 1977 sample. However the maximum length has
decreased. This and the fact that the older age classes (4 and older) are not present indicates that the fish are being harvested at an early age before they can attain larger size ranges. The age (composition seems to be skewed with fewer 0 plus present than 1 plus and 2 plus but this could
be attributed to the fact that fewer fish were planted in 1984 than the previous years, or that the net was more selective in catching larger fish. The management of this lake is directed towards providing a sport fishery where the angler has a good chance of catching pan sized fish and not a trophy fishery. The fish that are being produced in Co-op at the time of this study are still meeting the management objectives. It appears that the actual stocking rate could be greater than the calculated stocking rate (10,000 at 440kg) because the fish appear to be experiencing heavy exploitation. It is recommended to provide a higher level of stocking than stated by stocking calculations (approximately 50 percent higher i.e. 15,000 at 440kg), do an intensive creel census to determine exploitation rates for winter and summer fisheries and continue to monitor fish size and ages periodically (i.e. every four years) to determine the effects of the higher stocking rate and to ensure our management objectives are maintained.
