Final report on the 10 year limnological study initiated by the NPS in 1982 in response to an apparent decline in lake clarity and possible changes in the characteristics of the algal community. Congress passed a law in 1982 to authorize and direct this study. Study goals were to: "1) develop a limnological data base to be used for comparisons of future conditions of the lake; 2) develop a better understanding of physical, chemical and biological components of the lake system; 3) develop a long-term monitoring program; 4) determine if the lake had experienced recent changes, and if changes were present and human related; 5) identify the causes and recommend ways of mitigating the changes."(Excerpted and paraphrased from abstract.)
