Little Traverse Lake  Property Owners Association

The  LTLPOA Water Quality Committee is working with Ron Reimink of Freshwater Solutions, in coordination with other neighbor lake associations, testing for levels of human fecal pollution through Enteric Bacteria analysis. ​​​

The  LTLPOA has contracted Dr. Ray Canale to conduct a multi-year water quality monitoring program and develop an EXCEL database.   The off-shore program measures algal nutrients, water clarity, chlorophyll, and dissolved oxygen at multiple depths at a deep water site several times per year.  The near-shore program measures periphyton (including Cladophora) at nine locations.  Near-shore algal growth is a sensitive indicator of nutrient inputs from sources such as septic system drain fields and fertilizer run-off. A baseline survey of periphyton on Little Traverse Lake was conducted by volunteers in 2016. Broader studies continue by Dr. Canale.

These studies are coordinated by the Little Traverse Lake Water Quality Committee, a group of volunteers committed to understanding the environmental health of Little Traverse Lake.  They continue to partner with regional experts and community organizations in these efforts.
