Volunteer Lake Monitoring Program, 1990. Volume 7. Southern Illinois Region

摘要

The Illinois Environmental Protection Agency initiated the Illinois Volunteer Lake Monitoring Program (VLMP) in 1981 as a result of growing public interest in lakes and the need to expand the state's data base on lake water quality. The purpose of the VLMP is to involve volunteers with lake monitoring, thereby providing effective public education in lake ecology and management as well as a useful data base for site-specific and statewide lake quality assessment. The Regional Report volume is a compilation of lake monitoring data for lakes in the southern Illinois region. A regional lake location map and a ranking of lakes by average transparency is discussed in the section. Section II contains lake data and individual lake summaries for those VLMP lakes that were monitored during nine or more semi-monthly sampling periods in the 1990 season. Section III includes lake data for those VLMP lakes that were monitored during four to nine of the semi-monthly sampling periods. Data collected under IEPA's Ambient Lake Monitoring Program in 1989 is also included where available.
