Rainfall Event Creating Significant Response Near Churchill River

July 25, 2017 – The Water Security Agency (WSA) is advising the public of a significant rainfall event and response in the river systems in the Churchill River and Buffalo Narrows region.

Yesterday, the Churchill River basin saw general accumulations of 30-40 mm of rainfall over western portions of the basin with localized accumulations in excess of 60 mm in many locations. Since mid-April the area has experienced record or near record wet conditions.

Buffalo Narrows received 112 mm of rainfall during this event, much of which fell over a 12 hour period. This is well in excess of 1 in 100 year event over this duration. As a result, flows on tributaries to the Churchill River are expected to be increasing over the coming days and flows on the Churchill River itself, which were holding at or near peak levels, are expected to see increases over the coming weeks.

Areas upstream of Patunak are expected to see the most significant increases in flows and potential for flood damages from this event. The Churchill River at Patunak was already near 1 in 50 year levels prior to this rainfall event.

With increasing flows throughout the system, the public in the area is advised to use caution around watercourses within the basin and to take steps to protect property where necessary. Less experienced users and those lacking local knowledge of the watercourses should avoid accessing them altogether, as deep, fast moving water can pose a serious hazard.
