Abstract |
Internal loading of phosphorus has been implicated as a major eutrophication factor in Long Lake, WA. As a result of such loading, summer total phosphorus concentrations approach or exceed 100 micrograms P/l. Most of the summer loading of phosphorus is thought to have been released directly from the rich sediment in the mid and northern part of the lake as a result of high pH (up to 10) related to phytoplankton photosynthesis. The lake also supports a dense submersed macrophyte crop composed primarily of Elodea densa. During the summer of 1980 internal loading of phosphorus was reduced and total phosphorus remained below 50 micrograms/l. |
