Health Alerts End at Big Indian Creek Lake, Kirkman’s Cove and Swan Creek Lake #5A
The state has ended health alerts for toxic blue-green algae at Big Indian Creek Lake in Gage County, Kirkman’s Cove in Richardson County and Swan Creek Lake #5A (Willard L. Meyer Recreation Area) in Saline County. With the end of these alerts, there are currently no health alerts remaining in effect in Nebraska.
Weekly sampling has been conducted at 49 public lakes in Nebraska since the beginning of May. Health alerts are issued if a lake’s sample is above 20 parts per billion (ppb) of total microcystin (a toxin released by certain strains of blue-green algae.) After an alert is issued, the lake 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.
The lakes will continue to be monitored weekly throughout the 2012 recreational season. Sampling results for toxic algae and bacteria will be updated every Friday and posted on NDEQ’s web site, http://deq.ne.gov/.
