The report provides a historical perspective of the Volunteer Lake Monitoring Program and describes program objectives and rationale. Methods for volunteer training and data handling/analysis are described; 1993 program results are presented and discussed; and trends analyzed. Two hundred and eighty-five volunteers participated in monitoring 151 lakes in 1993; 140 lakes had data for 4 or more sampling periods and are included in this report. Average transparencies for the lakes ranged from 12 inches to 179 inches. Sixty-two percent of the 140 lakes monitored 4 or more sampling periods in 1993 had transparencies less than 4 feet; 21% were less than 2 feet. No lakes were classified as oligotrophic, 15 were classified as mesotrophic, and the remaining 125 lakes, eutrophic, based on average Secchi disc transparency.
