Health Alert Issued For Holmes Lake In Lincoln
The state has issued a health alert for toxic blue-green algae at Holmes Lake in Lincoln. A health alert also remains in effect for Iron Horse Trail Lake near DuBois in Pawnee, which was first placed on alert last week.
Samples taken June 30 at Holmes Lake were above the state’s health alert threshold of 20 parts per billion (ppb) of total Microcystins (a toxin released by certain strains of blue-green algae.) Although levels were below the threshold at Iron Horse Trail Lake this week, a health alert remains in effect. Lakes that are on health alert must have two consecutive weeks of readings below 20 ppb before the alert is removed.
Signs are being posted at both lakes to advise the public to use caution, and the swimming beach at Iron Horse Trail Lake will remain closed during the health alert. The public is advised to avoid activities that could involve accidental ingestion of water and to make sure their pets don’t drink from the lakes. People can still use the public areas for picnics and other outdoor activities.
Both lakes will continue to be monitored weekly throughout the 2008 recreational season. The state is also taking periodic samples at 45 other public recreational lakes through September. Sampling results for toxic algae and bacteria will be updated every Friday and posted on NDEQ’s web site, www.deq.state.ne.us .
