The state has issued new health alerts for harmful algal blooms, also known as toxic blue-green algae, at Willow Creek Reservoir in Pierce County, and Harlan County Reservoir in Harlan County. These are the first health alerts that have been issued for the 2019 recreational season.

Samples taken earlier this week at the two lakes were 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 alerts will continue at the lakes for at least two more weeks, because lakes that are on health alert must have two consecutive weeks of readings below the threshold before the alert is discontinued.

When a health alert is issued, signs are 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 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.

Weekly sampling has been conducted at 51 public lakes since the beginning of May. The lakes will continue to be monitored weekly through the end of September. Sampling results for harmful algal blooms and bacteria will be updated every Friday and posted on NDEE's web site, http://dee.ne.gov.
