Sentinel Lakes

The Sentinel Lakes are the focus of a long-term, collaborative monitoring effort that is being led by the Minnesota Department of Natural Resources (DNR). The Sustaining Lakes in a Changing Environment" (SLICE) program is designed to understand and predict the consequences of land use and climate change on lake habitats.

This program will involve long-term monitoring of water chemistry, fisheries, habitat, and other factors in these lakes as well as detailed assessment of watershed and related characteristics. The MPCA is a partner in this effort, with a primary focus on collection and assessment of water quality data for these lakes.

After completing the initial four-year (2008-2011) sampling of the 24 lakes, they were sorted into two tiers:
Note: Greenwood lake was added to the Sentinel Lakes program at that time as well.

  • Tier 1: Sampled annually
  • Tier 2: Sampled on a 10-year rotating watershed schedule by MPCA staff

This page provides a forum for sharing Sentinel Lake water quality-related reports. For questions about the webpage, contact MPCA's Lee Engel at 651-757-2339.
