State officials have issued a health alert for Holmes Lake in Lincoln.
Health alerts continue for Kirkman’s Cove in Richardson County and Maple Creek Recreation Area Lake in Colfax County.
All three lakes have been found to have levels of harmful algal blooms, also known as toxic blue-green algae, above the state’s health alert threshold.
Samples taken earlier this week at Holmes Lake 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), according to state officials.
Holmes Lake will remain under a health alert for at least two weeks. The state will not lift a health alert until a body of water passes two consecutive weeks of testing.
Algal blooms levels at Kirkman’s Cove and Maple Creek Lake dropped below the threshold during testing this week. If they pass the test next week, the health alerts will be lifted.
Swimming beaches are closed while the lakes remain under the health alerts. Recreational boating and fishing are permitted, but the public is advised not to get into the water or drink it. Pets should not be allowed in the water or allowed to drink it. Camping, picnics, and other outdoor activities are not affected.
Water samples are taken from all 51 public Nebraska lakes throughout the recreation season. The Nebraska Department of Environmental Quality posts updated sampling results each Friday. You can find them by clicking here for the website.
