(KLZA)-- Toxic algae levels have exceeded limits for safe contact with the water at Kirkman’s Cove Recreation Area near Humboldt and Iron Horse Trail Lake northwest of DuBois.
Both lakes have been placed on “Health Alert Status”, which means the swimming beaches are closed and all body contact activities including swimming, wading and water skiing are restricted until further notice.
Visitors to the parks are cautioned not to ingest or make contact with the water. You should make sure children and pets do not come in contact with the water. 
Most of the risk associated with this form of algae is limited to skin irritations; however, gastrointestinal illness and liver disease could result from ingestion of the water. 
The Nemaha Natural Resource District, which operates both lakes, says the recreation areas remain open, and all other usual activities such as boating, picnicking, camping and hiking are permitted. Fishing is still allowed, though anglers are encouraged to practice “catch and release” as the toxins could be present in the liver, intestines and pancreas of fish.
