Harmful Algal Bloom Recreational Public Health Advisory Removed

Test results below advisory levels on the Ohio River

FRANKFORT, Ky. (Nov. 7, 2019) – The Kentucky Division of Water (DOW) and the Kentucky Department for Public Health (DPH) have removed the recreational public health advisory for the Ohio River previously issued due to harmful algal blooms (HABs). Results from recent water samples collected throughout the advisory area from the McAlpine Dam near Louisville to the Greenup Dam near Greenup are below the recreational advisory threshold for microcystin toxins.

The recreational public health advisory was issued Sept. 26 when sample results from the river indicated the presence of toxin-producing algal blooms. Since that time, regular testing has occurred to monitor microcystin levels. Although the advisory is being removed, the DOW and DPH advise there are always risks associated with recreating in natural waters, especially with the incidental ingestion of water, and recommend avoiding contact with waters that have visible algal blooms.

An advisory remains in effect for Briggs Lake near Russellville.
