Chris Filstrup

Inland Lakes Specialist

Chris is a lake scientist with the Minnesota Sea Grant and the Large Lakes Observatory at the University of Minnesota Duluth. He studies lake response to nutrient enrichment, environmental conditions favoring toxic cyanobacteria (i.e., blue-green algae) blooms, and nutrient recycling within lakes.

Human activities within watersheds contribute to large amounts of nutrients moving from land to streams and lakes, which can cause low water clarity, green surface scums, fish kills, and accumulation of cyanobacteria toxins in lakes.

Chris and colleagues seek to develop strategies to prevent these water quality issues in pristine lakes and reverse these processes to restore lakes with poor water quality to their natural state.

Chris is also a member in the Water Resources Science Graduate Program in the Water Resources Center, University of Minnesota.
