Aquatic Plant Sampling!

Data collection under the MiCorps Cooperative Lakes Monitoring Program (CLMP) is suspended for 2020. Funding has been secured to resume the CLMP in 2021 and into the future from the Michigan Department of Environment, Great Lakes, and Energy (EGLE).

If you want to monitor your lake in 2020, you have options. 

We, the non-governmental partners of CLMP (Michigan Lakes and Streams Association, Michigan State University and Extension, and the Huron River Watershed Council), who were previously contracted to administer the CLMP, are offering the following monitoring options in place of the CLMP for 2020.  There will be no enrollment fees charged in 2020, due to the limited program we are offering. See the options below.

When the new CLMP database comes back online in 2021, our intent is that you will be able to submit your 2020 data for approval and inclusion, as long as all CLMP procedures are followed for the parameters collected. If you sign up for the Exotic Aquatic Program, we will want your datasheets by the end of this field season as normal, but for all other datasheets, hold on to them until the CLMP comes back in 2021.

Get out this summer and let’s prove the resilience and the dedication of Michiganders.  The CLMP will only be down for a year and it will come back bigger and better than ever.  In the meantime, let’s do all we can to keep the long-term records on our lakes unblemished!

No enrollment fees for 2020.

We will provide technical support for the following parameters:

Secchi Disk:  Secchi Disk Transparency can be conducted the same as always. Training is not required. You can view a training video here. You do not need to enroll; simply record your measurements and hold onto them. If you need a new Secchi Disk, please visit MLSA at:

Exotic Aquatic Plant Watch:  Michigan State University and Extension have a separate contract with the state to offer the Exotic Aquatic Plant Watch, so this parameter will continue as usual, but with no enrollment fees. You must contact Jo Latimore at MSU ( or 517-432-1491) by May 30 to confirm that you will be conducting the Exotic Aquatic Plant Watch. As usual, training is required for lakes new to the Exotic Aquatic Plant Watch. Training arrangements can be made with Jo Latimore.  We hope to be able to offer field visits to selected lakes to support your invasive plant monitoring efforts; priority will be given to lakes or volunteers new to the program.

Score the Shore:  You must have attended a previous training for this parameter, and you must follow the CLMP procedures. Do not attempt this if you have not been trained; wait until 2021 when training will be offered again. We are not able to provide technical support or field visits for Score the Shore in 2020. 

2020 Datasheets


Dissolved Oxygen and Temperature: You must have your own DO meter, and you must follow CLMP procedures. CLMP-owned meters are not available for loan in 2020. Acceptable meters are the YSI Pro20 and the YSI 550. If you do not use one of these meters, you will not be able to upload your data to the database when CLMP 2021 arrives. If you wish to purchase a DO meter, Michigan Lake and Streams Association can provide guidance (

We are not able to provide technical support or field visits for DO/Temperature in 2020.

Aquatic Plant Identification and Mapping: Only for lakes that have previously conducted this parameter, and you must follow CLMP procedures. No new lakes. Limited technical support will be available, via email or phone call with Jo Latimore <> We are not able to provide field visits for Aquatic Plant Identification and Mapping in 2020. 


Total Phosphorus and Chlorophyll

Phosphorus and Chlorophyll sample analysis for the statewide monitoring program requires EGLE’s laboratory and logistical support for long-term consistency and quality assurance. When CLMP returns in 2021, no Phosphorus or Chlorophyll samples collected in 2020 will be accepted. Nor will data from samples analyzed by other laboratories. No exceptions. 

If you are interested in contracting with another laboratory to analyze Phosphorus or Chlorophyll samples that you collect, Michigan Lakes and Streams Association can provide contact information for laboratories (
