Three areas of Lake Tenkiller are closed due to high levels of E. Coli.
The U.S. Army Corps of Engineers Tulsa District closed the Snake Creek, Chicken Creek and Cookson Bend swim beaches on Monday.
Swimming areas a will remain closed until further sampling concludes the beaches are safe. The closure only affects the swim areas at Snake Creek, Chicken Creek and Cookson Bend. Campgrounds and boat ramps will remain open.
Park Rangers collect water samples from Corps Lake swim areas each week. Testing is conducted by the Tulsa County Health Department. If a swim area fails to meet established water quality standards it is re-sampled and tested within 24 hours. A second failure results in closure of the affected swim area.
Monday's announcement is the second beach closure due to E. Coli in eastern Oklahoma this month.
A beach on Grand Lake has been closed since June 3. with the same issue.
