2014 Assiniboine River flood

The 2014 Assiniboine River flood was caused by above average precipitation in western Manitoba and Saskatchewan.

[2][3] After a generally unremarkable spring in the Assiniboine River watershed with some minor flooding, a series of significant rainfall events occurred in June and early July with the most significant event occurring in Eastern Saskatchewan and Western Manitoba over the Canada Day long weekend.

Dikes were reinforced and built up along the Portage Diversion as well in order for the channel to run above design capacity.

Preparations were also made at the Hoop and Holler bend on Provincial Road 331 in the event a controlled breach of the lower Assiniboine River was needed to handle excess flows beyond the capacity of flood control measures.

[11] On July 12, the second crest reached Brandon and peak flows were measured at 38,870 cfs, which was higher than 2011 levels.

However, even with the restriction of flows on the lower Assiniboine River to about 18,000 cfs property damage occurred.
