Harmful Algal Blooms (HABs)

Algal blooms have become more noticeable in Ohio’s lakes, streams and rivers during the last few years.

Although most blooms are green algae and not harmful, there are some that are actually a type of cyanobacteria that have the ability to produce toxins – called harmful algal blooms (HABs).

WHEN IN DOUBT, STAY OUT!

Remember, you can still boat, fish and recreate in Ohio’s lakes, streams and rivers. Just be aware that HABs exist. We hope the links to the information below will give you a better idea of what HABs can look like and provide you with the information you need to safely enjoy Ohio's waterways.
