An oil spill near Gull Lake is currently being cleaned up by the Government of Saskatchewan.

The spill stretches down a 19-kilometre stretch of Highway 37, beginning at the Trans-Canada Highway. The cleanup has required 450 tonnes of sand to absorb the spill. 

The cause of the spill is believed to be from a tanker truck hauling the product from an unknown location, between 2 and 3:30 p.m. on Monday.

Motorists are being advised of loose stones via signage during the cleanup, due to the sand. 

An investigation is actively taking place, with people being asked to call their local conservation officer with any details, or the Saskatchewan Turn in Poachers and Polluters line at 1-800-667-7561.
