The state has issued a health alert for toxic blue-green algae at Swan Creek 5A Lake near Tobias in Saline County. This is the first health alert issued for the 2010 season. Weekly sampling has been conducted at 46 public lakes in Nebraska since the beginning of May.

Signs are being posted to advise the public to use caution, and the swimming beach at the lake will remain closed during the health alert. Recreational boating and fishing are permitted at the lake, but the public is advised to avoid activities that could involve accidental ingestion of 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 2010 recreational season. Sampling results for toxic algae and bacteria will be updated every Friday and posted on NDEQ’s web site, https://dee.nebraska.gov/home.
