Large Lake Assessments

For the purpose of future water planning, a grant funded by the Minnesota Board of Water and Soil Resources (BWSR) and the Initiative Foundation was used to evaluate the water quality of the largest lakes (over 500 acres in size) in Crow Wing County. Crow Wing County large lakes have been monitored off and on between 1970 and present-day. This monitoring has been completed by numerous organizations including:

  • Crow Wing SWCD
  • Lake Associations
  • Minnesota Department of Natural Resources
  • Minnesota Pollution Control Agency
  • The Outdoor Corps Program (University of Minnesota)
  • Thirty Lakes Watershed District

Lake Water Quality & Watershed Information Map

- A map showing the lake water quality trend for the larger lakes in Crow Wing County. Users can click on the lake to pull up additional information, including links to water quality reports and factsheets as well as the lake association website.


The purpose of these reports was to compile all available data for these lakes from all the different sources, evaluate the data quality, identify data gaps, assess the data, and look for water quality trends. These reports contain a summary of the current state of large Crow Wing County lakes and recommendations for future monitoring. Individual lake reports and a summary report for the project are located to the left. Report compilation and data assessment was provided by Moriya Rufer and Jason Vinje of RMB Environmental Laboratories, Inc.
