Report a Suspected Bloom

Hot Weather Cold Water


High temperatures are just around the corner, but lakes and rivers are still cold enough to shock and immobilize even the strongest swimmers. Rivers are still high and swift from rain and snow melt and may be carrying debris in late spring and early summer.


4 Tips to Stay Safe


  1. Avoid fast-flowing waters.
  2. Wear a life jacket,
  3. Supervise children around all water
  4. Swim with a buddy.




Know How to Spot an Algal Bloom

When swimming or recreating in local waterbodies, be sure to keep an eye out for harmful algal blooms. Toxins from harmful algae or cyanobacteria can make people sick and can be fatal to pets.

Do you know how to spot a bloom of harmful algae? Here are some things to watch for:

  • Blooms can look like foam or scum on the surface of the water.
  • They can also look like a mat or streaks of paint in the water.
  • On the shore, algae blooms can look like clumps where foam or scum dried.
  • Harmful algae is typically green but may also be blue, red, or brown.
  • The water may also smell like rotting plants.



And remember: When in doubt, stay out!
