Abstract

This paper summarizes the development of a limnological study of Crater Lake conducted between 1983 and 1992. The program was mandated by Congress in the fall of 1982 after a panel of limnologists found the lake data base (1896–1981) to be inadequate to determine if the phytoplankton community had changed and if the lake was decreasing in clarity as suggested from independent studies between 1978 and 1981. Congress authorized and directed the Secretary of the Interior to promptly instigate studies and investigations as to the status and trends of changes of water quality and to immediately implement such actions as necessary to assure the retention of the lake's natural pristine water quality. Program goals were to develop a detailed data base and an understanding of physical, chemical, and biological characteristics and processes of the lake. Ecological relationships among trophic levels and environmental conditions were stressed to evaluate the hypothesis that the lake had changed in water quality and clarity.
