Health alert continued at Richardson Co lake
07/22/2025

(KLZA)-- The state of Nebraska has extended a health alert for Kirkman's Cove Lake near Humboldt due to the presence of blue-green algae.

According to a release, samples taken earlier last week from the lake measured above the threshold of eight parts per billion (ppb) of total microcystin, which is a toxin released by certain strains of blue-green algae.

Signs have been posted to advise the public to use caution, and designated swimming beaches are closed during the alert.

Recreational boating and fishing are permitted, but the public is advised to use caution and avoid exposure to the water, particularly by avoiding any activity that could lead to swallowing the water. Do not let pets get in the water or drink from the lake.

People can still use the public areas for camping, picnics, and other outdoor activities.
