ACLPOA’s Lake Monitoring Commission is part of the Illinois Environmental Protection Agency’s established Tiered Approach program. The structure was developed to take into account the needs of both the Illinois EPA and volunteers by establishing different levels of volunteer participation and data use. ACLPOA is currently a Tier Two Volunteer Lake Monitoring Program (VLMP) member.
Tier 1 – In this tier, volunteers perform Secchi disk transparency monitoring and record field observations. Monitoring is conducted twice per month from May through October typically at 3 in-lake sites.
Tier 2 – In addition to monitoring Secchi disk transparency, Tier 2 volunteers enter the advanced water quality program by collecting water samples for nutrient and suspended solid analyses at Site 1. Water quality samples are taken once per month in May through August and October in conjunction with one Secchi transparency monitoring trip.
Tier 3 – This is the most intensive tier. In addition to monitoring Secchi disk transparency, Tier 3 volunteers are also part of the advanced water quality program and collect water samples at up to 3 sites on their lake. As in Tier 2, their samples are analyzed for nutrients and suspended solids; however, they also collect an additional parameter: chlorophyll. With this additional parameter, volunteers must collect and filter their own chlorophyll samples. This tier may also include dissolved oxygen/temperature profiles as equipment is available. As in Tier 2, water quality samples are taken once per month in May through August and October in conjunction with one Secchi transparency monitoring trip.
The Commission will prepare a summary of activities and projects they have been involved in over the past year for presentation at the Annual Meeting.
