Larson DW, Forbes ME, Jarvis JB. 1983. First Annual Report on the Limnology and Water Quality Monitoring Program at Crater Lake National Park, Oregon.1982.. NPS. Pacific Northwest Region, Seattle, WA.
In 1982, the National Park Service provided funds in the amount of $30,000 for a limnological monitoring program at Crater Lake National Park. This action was prompted by a study which indicated that Crater Lake had undergone an estimated 25-30 percent reduction in epilimnetic transparency (from surface to 40 meters, approximately) in less than 15 years, as determined by Secchi disk and Kahl photometer (Table1). Initially the monitoring program was envisioned as having three objectives: 1. Provide the NPS with reliable baseline limnological data for use as a benchmark, or basis for comparision. 2. Gain a better understanding of the lake's physical, chemcial and biological properties and of how these elements interact to produce the unique limnological character of Crater Lake. 3. Develop an applied research capability so that cause-effect relationships, might be ascertained.
