Abstract |
The report is Vol. 2 of a series of 7 reports summarizing Illinois EPA's 1986 Volunteer Lake Monitoring Program. It provides a program overview, summarizes results for 21 lakes in Northwestern Illinois, and discusses lake/watershed management strategies. It also contains individual analyses and recommendations for lakes monitored during 9 or more sampling periods, and data for lakes monitored 4-8 sampling periods. Nineteen volunteers recorded total depth, Secchi disc transparency, and field observations for 21 lakes in Northwestern Illinois between May and October, 1986. Included were 18 dammed-stream type impoundments, 1 strip mine lake, 1 river backwater, and 1 excavated lake. Average transparencies ranged from 10.8-93.3 inches. |
