In response to apparent changes in the water quality of Crater Lake, the National Park Service convened two workshops early in 1982 to evaluate the lake data base and then sponsored the limnological studies the following summer. In September of 1982, Congress mandated the Secretary of the Interior to initiate a ten-year program to develop an adequate data base and an understanding of physical, chemical, and biological characteristics and processes of the lake. Development of the program from 1982 to 1985 is described. The main objective is to stress ecological relationships among trophic levels and environmental conditions to bring a more holistic approach to the baseline data in order to evaluate the hypothesis that the lake has changed.
