Abstract : Postimpoundment loadings of total nitrogen and total phosphorus delivered to Lake Koocanusa by the principal inflowing stream, the Kootenai River, were predicted to be large enough to cause eutrophication of the lake; however, measured annual primary productivity for 1972 through 1975 was relatively low, and characteristic of oligotrophic waters. It was hypothesized that primary productivity was limited to oligotrophic values because phytoplankton photosynthesis was suppressed by physical limnological factors.
