A new health alert has been issued for a Nebraska lake.
State officials report a health alert for toxic blue-green algae has been issued for northeastern Nebraska’s Willow Creek Reservoir in Pierce County.
A health alert continues for Rockford Lake in Gage County in southeastern Nebraska.
The health alert was issued for Willow Creek when samples taken from the lake indicated the reservoir was above the state’s health alert threshold of 20 parts per billion (ppb) of total microcystin (a toxin released by certain strains of blue-green algae.)
The alert will be in place for at least two more weeks. Readings taken from lakes must be below the state threshold for two consecutive weeks before an alert is lifted.
The health alert issued for Rockford Lake will continue for at least another week.
Swimming beaches at the two lakes are closed. Recreational boating and fishing are permitted. Camping, picnics, and other outdoor activities are still allowed. The public is advised to not drink water from the lakes or jump in the lakes.
State officials monitor Nebraska lakes weekly during the summer vacation season.
Sampling results for toxic algae and bacteria will be updated every Friday and posted on NDEQ’s web site, deq.ne.gov.
