Two lakes in southeast Nebraska are on a health alert for toxic blue-green algae.
The Nebraska Department of Environmental Quality and Nebraska Health Department report Rockford Lake southeast of Beatrice in Gage County, and Swan Creek Lake #5, near Tobias in Saline County, have been placed on the health alert list.
During alerts, swimming beaches are closed, but boating and other recreational activities are allowed.
Officials urge people not to have prolonged contact with the water during the health alerts.
Readings above 20 parts-per-billion of microcystin over a two-week period, prompt the issuance of a health alert for blue-green algae.
The latest measurement at Rockford Lake was 31.46 parts per billion. At Swan Lake #5, the latest reading was 24.09 parts-per-billion.
