MiCorps’ Cooperative Lakes Monitoring Program (CLMP) provides technical assistance, training, and other support to volunteer lake monitors in Michigan to ensure that they are collecting reliable, high-quality data.
The CLMP has been an important component of Michigan’s inland lakes monitoring program for over 40 years, which makes it the second oldest volunteer monitoring program for lakes in the country. The primary purpose of this cooperative program is to help citizen volunteers monitor indicators of water quality in their lake and document changes in lake quality over time.
Since 1992, the Michigan Lake and Stream Associations (MLSA) has administered the CLMP jointly with the Michigan DEQ under a Memorandum of Understanding. MLSA – in partnership with the Great Lakes Commission, the Huron River Watershed Council, and the Michigan DEQ – continues to support the administration of the CLMP, which is now a component of the MiCorps programming. Michigan State University’s Department of Fisheries and Wildlife also supports the partnership with technical assistance.
For more information, see the CLMP Manual.
Monitoring your lake’s water quality is part of what’s needed to keep it clean for the enjoyment of you and yours for generations to come. By monitoring, you’ll know if your lake continues to be ready for fun and recreation, or if it’s starting to degrade over time. And if there is a water quality problem, only monitoring will give you the advance warning needed to take early action to protect your lake. Enroll in the CLMP to start monitoring, and protecting, your valued lake.
The CLMP provides sampling methods, training workshops, technical support, quality control, and laboratory assistance for volunteers to monitor their lakes.

CLMP volunteers monitor for indicators of lake productivity, or the amount of plant and animal life that can be produced within the lake. The gradual increase of lake productivity over time is a natural process called eutrophication, or lake aging. Impaired water quality can often cause excessive lake productivity, leading to problems such as excessive plant growth, algal blooms, and mucky bottom sediments. A primary objective of most lake management plans is to slow down eutrophication by reducing the input of plant nutrients, such as phosphorus, and sediments to the lakes.
Lake scientists have developed a variety of numerical indexes based on water quality data to express lake productivity on a numerical scale. The widely used Carlson Trophic State Index (TSI) incorporates water clarity, or transparency, as measured by a Secchi disk; the algal plant pigment chlorophyll a; and total phosphorus as indicators of lake productivity. The CLMP was designed to provide data on these parameters. Volunteers may classify their lake according to its level of productivity, or trophic state, using Carlson’s TSI. Long-term monitoring of these parameters on a consistent and regular basis provides the data needed to recognize changes or trends in lake productivity.

Education and Training
Training Events and Materials: The MiCorps program offers training opportunities for both current and aspiring MiCorps volunteers. The CLMP training sessions focus on each specific monitoring program and how each type of monitoring can tell you something different about the health of your lake.
MiCorps Conference: The annual MiCorps conference, typically held in late fall, provides education and additional training opportunities for volunteer monitors and program leaders.
The CLMP offers training and technical assistance for the following volunteer lake monitoring programs:
- Secchi Disk Fact Sheet
- Total Phosphorus Fact Sheet
- Chlorophyll-a Fact Sheet
- Dissolved Oxygen and Temperature Fact Sheet
- Aquatic Plant Fact Sheet
- Exotic Aquatic Plant Fact Sheet | Brochure
- Score the Shore Fact Sheet
