Water Quality

Chisago County

Chisago County implements a Water Quality Monitoring Program to monitor lakes for water clarity, nutrient levels, watercolor, and algae abundance.  Yearly monitoring provides a basis for determining the improvement or degradation of water quality over time. 

Chisago County staff monitor the following lakes each year: East Rush, Fish, Horseshoe, Mandall, North Goose, Rabour, South Goose and West Rush Lakes.  Visit the monitoring reports below to see how the lakes rank from highest water quality to lowest quality. 

Chisago Lakes Lake Improvement District

One of the goals of the Lake Improvement District is to preserve, protect and enhance water quality within the Chisago Lakes Watershed. This goal is accomplished through monitoring lakes for water quality, support adoption of uniform water protection ordinances, and participation in projects that will help meet the goals of the Chisago Lakes Chain of Lakes.

Chisago County staff monitor the following lakes located in the Chisago Lakes Lake Improvement District each year:  Chisago, Green, Kroon, Little, Little Green, North Center, North Lindstrom, South Center, South Lindstrom and Spider Lakes.  Volunteers monitor Bloom, Emily, Linn, Mattson, Ogren, Pioneer, School, Swamp and Wallmark Lakes.  Visit the monitoring reports below to see how the lakes rank from highest water quality to lowest quality.
