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.
