North Lake Studies

​The goal of the NLPA is to fulfill our mission to protect the ecological, recreational, and aesthetic well-being of North Lake.  This entails a proactive approach to problems while controlling any potential adverse impacts to the lake.


In the past, independent water quality monitoring was conducted by NLPA through a trained cadre of volunteers in association with MiCORPS' Cooperative Lakes Monitoring Program (CLMP).  MiCORPS is a state organization that trains and provides support to lake associations.  Initial funding for the MiCORPs program was provided through the Clean Michigan Initiative (CMI) bond; however, due to the exhaustion of the CMI funds, MiCorps has dealt with uncertainty in the past few years while trying to find another long-term funding source. 

EGLE (Department of Environment, Great Lakes, and Energy) recently announced that funding has been secured from Renew Michigan Initiative in order to create a new five-year contract for the MICorps program.  However, due to the timing of acquiring this funding and the necessary transition to initiate a new contract, the CLMP program was not be funded in 2020, but will return in 2021 under a different entity.

In spite of the discontinuance of the CLMP program in 2020, North Lake volunteers will continue to monitor the lake through any testing we can do on our own.  This will include such things as water clarity and temperature.  We look forward to the full CLMP program starting once again in 2021. 


In 1988 and 1992 North Lake studies were performed by Freshwater Physicians, Inc.  Freshwater Physicians did an additional survey in 1994 somewhat different from the 1988 and 1992 studies. However, they provide a comparison with those studies where the parameters are the same.  From 1993-2010 NLPA contracted with Wallace E. Fusilier, Ph.D. and Bene Fusilier, M.A., Consulting Limnologists for water quality studies. Summaries of all these reports are provided below.  The CLMP annual reports will be provided in the future as they become available.
