The Department of Health and Human Services has added a Saline County lake to the list of Nebraska lakes containing toxic blue-green algae.
A health alert has been issued for Swan Creek 5A Lake. The lake joins Willow Creek Lake in Pierce County on the list, while health alerts have ended for Bluestem Lake in Lancaster County and Kirkman's Cove in Richardson County.
Swan Creek Lake and Willow Creek Lake this week both tested above the state's health alert threshold for microcystin, a toxin released by certain strains of blue-green algae. Willow Creek Lake has been on the list since Sept. 2.
Alerts at these two lakes will continue for at least two more weeks as two consecutive negative tests must occur before they can be removed from the list.
Recreational boating and fishing are permitted in these lakes, but the public is advised to avoid activities that could involve accidental ingestion of water or full immersion into the water as doing so may lead to skin rashes, lesions, blisters or other serious symptoms.
