Algae Bloom Monitoring for the Ohio River

ORSANCO is working closely with Ohio, Indiana and Kentucky to monitor an algae bloom in the Ohio River, in the Cincinnati / Northern Kentucky area.

ORSANCO coordinates sample collection and lab analysis with member states. The data from these samples are available. Click here to read the data.  These data are also available as maps.

The public should continue to exhibit caution and review the health and safety information below that is provided in the links by ORSANCO’s member states. People recreating on the Ohio River should be alert, and avoid water that:

  • Looks like spilled paint
  • Has surface scums, mats or films
  • Is discolored or has colored streaks
  • Has green globs floating below the surface
