The purpose of the Water Quality and Lake Level Committee is to monitor and assess the water quality, biological integrity, habitat condition and water level in Rennie Lake and the Rennie Lake watershed.

Duties and Responsibilities: Coordinate the monitoring and assessment of water quality, biological integrity and habitat condition in Rennie Lake and the Rennie Lake watershed. Coordinate the recording of water level observations or measurements in Rennie Lake. Produce and distribute an annual report summarizing the monitoring results and health status of Rennie Lake. Produce and distribute lake quality monitoring updates and lake science and management educational material via the Association’s web site and electronic newsletter (Reflections).

Michigan Clean Water Corps (MiCorps) - Cooperative Lakes Monitoring Program (CLMP)

Each year a portion of Rennie Lake Association member dues goes toward enrolling Rennie Lake in the Michigan Clean Water Corps - Cooperative Lakes Monitoring Program (MiCorps-CLMP) for water quality and lake habitat monitoring and assessment. Rennie Lake has been enrolled since 2015 and has a good start building a long-term data base for water quality status and trends assessment. The RLA Water Quality Committee will continue annual monitoring under the MiCorps-CLMP because it a key part of the RLA's mission. Go to the MiCorps-CLMP website (https://micorps.net/) for more information about the program.
