||A volunteer Lake Monitoring Program initiated by the Illinois EPA in 1981 was continued through 1992. Citizens were trained to measure Secchi disc transparency, total depth, and record field observations from a boat at three sites on their chosen lake, twice per month from May through October. This report provides a summary of the 1991 program conducted in the Southwestern Illinois Region. Eighteen volunteers participated in monitoring eleven lakes. Regional results are analyzed and compared with statewide results. Individual lake summaries are provided for lakes sampled six or more periods during the season, and data is provided for lakes sampled by the Illinois EPA under the Ambient Lake Monitoring Program.
