Cow Creek Reservoir Closed Due to Algae

CHINOOK, Mont. (NMB) – In a press release on Friday, the Montana Department of Environmental Quality announced the closure of the Cow Creek Reservoir due to a high level of algae.

Blaine County health officials reported Thursday that a test performed for cyanotoxins associated with a blue-green algae bloom at Cow Creek Reservoir returned with high results. As a result, state and local health officials recommend the reservoir, southwest of Chinook, be closed to all recreation and that pets and livestock be kept away from these waters.

These types of algal blooms are native to freshwater lakes and reservoirs in Montana. The algae blooms float on the surface of the water and may look like pea soup, grass clippings, or green latex paint.

If you suspect a toxic algae-related illness in a person or animal, including livestock, call Poison Control immediately at 1-800-222-1222 and/or contact Blaine County Sanitarian Ron Andersen at: 406-868-4957
