Water Chemistry Monitoring





       


Water chemistry volunteers measure phosphorus levels, chlorophyll-A concentrations (a measure of algae growth in the water), water clarity, and a temperature profile from the top to the bottom of the lake. This type of monitoring is done four times per year, and requires several hours of time during each monitoring event. Chemistry monitoring helps determine if nutrient pollution is occurring in a lake, or if seasonal fish die-offs may be a possibility due to low oxygen levels.

*NEW* Interpretive Guide to CLMN Annual Reports​

 

Use this short guide to interpret the data that is included in your lake's annual reports.


Understanding Lake Data​ (A guide to interpreting lake data)

This guide was written to help people understand information about lake water quality and to interpret lake data. Each lake possesses a unique “personality,” or set of physical and chemical characteristics which may change over time. Lakes exhibit chemical changes on a daily basis while other changes, such as plant and algae growth, occur seasonally. A glossary of technical terms is included to help the reader understand the language used in the study of lakes (limnology). ​
