Minnesota’s reputation for high-quality water may be increasingly stressed in the not-so-distant future. We are not alone. Regions throughout the country are experiencing the effects of climate change. Our 12,000+ shimmering blue lakes are increasingly turning green with algae, some of which can produce toxins. Although our state has an abundance of clear water right now, increased attention and effective strategies are needed to protect and conserve our water resources for our children and future generations.

We want to put a little attention on the water that makes our beer taste great, gives our kids and ourselves a place to swim, makes our dogs’ day, and makes Minnesota the great state of lakes.


Join Minnesota Sea Grant inland lakes specialist Chris Filstrup for a free, public-friendly talk on harmful algal blooms or HABs. Learn how you can use the crowdsourcing Bloomwatch app to find and report HABs using a smartphone. The presentation will address:

  • What is a HAB?
  • Why are HABs bad for beer, pets, and people?
  • Will HABs increase in Minnesota as the climate changes?
  • Steps you can take to reduce HABs on your favorite lake.
  • How to protect the people and pets you care about.


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