A health alert has been issued for another Nebraska lake and health alerts remain in effect for two others.
The Nebraska Department of Environmental Quality reports Swan Creek Lake #5, also known as Willard Meyer Recreational Area, in Saline County has been placed under alert for toxic blue-green algae.
Alerts remain in effect for Pawnee Lake in Lancaster County and Willow Creek Lake in Pierce County.
Samples taken from the lakes register blue-green algae levels about the state threshold of 20 parts per billion (ppb) of total microcystin (a toxin released by certain strains of blue-green algae.)
The alerts will remain in effect for at least two more weeks, because lakes have to pass two consecutive weeks of testing before alerts are lifted.
Under an alert, swimming beaches are closed. Recreational boating and fishing are permitted, but the public is advised not to submerge in the water. Public picnic and camping areas remain open.
Weekly sampling has been conducted at 50 public lakes in Nebraska since the beginning of May. Monitoring continues through the end of September.
