Story Maps
Serpent Lake
Serpent Lake is located between the City of Crosby and the City of Deerwood. These cities are within Crow Wing County, Minnesota. It covers 1,103 acres, which places it in the upper 10% for size of lakes in Minnesota.
In 2003, an algae bloom, triggered by an over-abundance of phosphorous, turned Serpent Lake green. Water clarity dropped to 15 feet. It got progressively worse, dropping to 12.1 feet by 2012. Under natural conditions, phosphorus is typically scarce in water. Human activities, however, have resulted in excessive phosphorus loading into our lakes.
Click on the map below to learn more about how local partners came together to reduce the phosphorous input into Serpent Lake by 80 pounds of phosphorus or 20 tons of potential algae growth.
Projects
In progress.

Chloride Monitoring
Since 2019, ten lakes have been monitored in partnership with the Crow Wing County Highway Department. Lakes were selected based on their proximity to major highways. These lakes are sampled in the spring, summer, and fall.
