Lower Flathead River Fisheries Study, 1983 Annual Report.
In January of 1983 a two-phase study of the lower Flathead River was initiated by the Confederated Salish and Kootenai Tribes with funding provided by the Bonneville Power Administration. The study fulfills program measure 804 (a) (3) of the Columbia River Basin Fish and Wildlife Program. During 1983 Phase I of the study was completed resulting in a detailed study plan for the next four years and the methods to be employed during the study. Preliminary observations suggest the present operation of Kerr hydroelectric facility and land use practices within the drainage have combined to significantly reduce spawning success of salmonids and northern pike, and thus recruitment to the fisheries of the main river and tributaries. Main river spawning marshes were observed to be drained frequently during the northern pike spawning season which would result in desiccation of eggs and loss of attached fry. Water level fluctuations also caused trapping of juvenile fish and may be an important source of juvenile mortality.
