INDIANAPOLIS (WTHR) — The Indiana Department of Environmental Management says that seven lakes in the state have high levels of blue-green algae.

The algae has made headlines in the past week after several dogs died from swimming in lakes with high levels of the algae.

IDEM has now posted a "Recreation Caution" for ​Mississinewa Lake - Miami SRA.

The following areas are on an advisory for "high cell alert" for blue-green algae:

  • Hardy Lake - Hardy Lake SRA
  • Monroe Lake - Fairfax SRA
  • Monroe Lake - Paynetown SRA

The algae is actually a bacteria found in freshwater lakes, streams and ponds, according to It can produce toxins that can be deadly to pets and harmful to humans.
