| Abstract |
Flathead Lake, a dimictic oligotrophic lake located in western Montana, has been the subject of several investigations beginning with Forbes' study of aquatic invertebrates in the lake in 1893. Young in 1935 presented the results of four years of data collecting on the chemistry and biology of the lake. During the last ten years (1964-1974) a number of limnological studies have been conducted dealing with the physical, chemical, and biological characteristics of the lake. The objectives of these studies have been to determine the standing crop of phytoplankton and zooplankton during all seasons of the year, to observe the succession, distribution and diversity of planktonic forms, to determine the role of chemical nutrients in relationship to phytoplankton productivity, and to study fish population trends, life histories and seasonal fish distribution of the Flathead Lake system. |
