SLICE: Sustaining Lakes
In A Changing Environment

Sustaining Lakes In A Changing Environment logoMinnesota's environment is changing, and its lakes will feel the effects. Some of those impacts can be apparent – changing fish populations ... fewer native aquatic plants ... more non-native plants ... water that is less clear. But long before these obvious differences appear, the biology of change has been hard at work. Minute biological and chemical changes begin small and grow until they combine to alter a lake's character. By the time humans have noticed the differences, the opportunity to stop or slow change has passed. The lake that once was never will be again.

The Section of Fisheries of the Minnesota Department of Natural Resources is leading a statewide, collaborative effort to develop a system to monitor and record biological and chemical changes that occur in a sample of lakes that are representative of the state's most common aquatic environments. Information gathered will be used to develop management approaches that can mitigate or minimize negative impacts caused by conventional "high-impact" residential development and agriculture, aquatic plant removal, invasive species and climate change.
