Health Alerts Issued for Big Indian Creek Lake, Swan Creek Lake 5A; Alert Continues at Iron Horse Trail Lake

Posted By: Channel 8 Eyewitness News

The state has issued health alerts for toxic blue-green algae at Big Indian Creek Lake in Gage County and Swan Creek Lake #5A, (also known as Willard Meyer Recreational Area) in Saline County.   An alert continues to be in effect for Iron Horse Trail Lake in Pawnee County. 

Samples taken earlier this week at Big Indian Creek Lake and Swan Creek Lake 5A 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.)  Although readings at Iron Horse Trail Lake were low this week, the alert continues to be in effect, 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 avoid activities that could involve accidental ingestion of water and to avoid full immersion in water.  People can still use the public areas for camping, picnics and other outdoor activities.

Weekly sampling has been conducted at 50 public lakes in Nebraska since the beginning of May.  The lakes will continue to be monitored weekly throughout the 2016 recreational season.  Sampling results for toxic algae and bacteria will be updated every Friday and posted on NDEQ’s web site,
