UPDATE: Oil-like Substance on Bow River Contained

Earlier today, the Calgary Fire Department responded to reports of an unknown substance in the Bow River and the Western Irrigation Canal near Harvie Passage.

Working with Alberta Environment and City Water Services, crews have contained the oil-like residue with further analysis pending to determine its nature and origin. Two booms have been installed on the Western Irrigation Canal to contain any further residue, along with a third, smaller boom on a storm water outflow on the Bow River.

Water Services will continue to monitor the site over the weekend and remove any additional residue as needed.

While there is no public hazard at this time related to the residue, The City’s Bow River boating advisory issued June 1st 2017 is still in effect and members of the public are strongly advised not to enter or float the river due to seasonally high flow rates.
