Town of Canmore

Seasonal High Water Monitoring

June 10: Some concerns in the one-week forecast. The snowpack in the Bow River Watershed is within the normal seasonal range for this time of year. In the Cougar Creek watershed, minimal snow remains on northerly slopes at treeline; minimal snow remains on southerly aspects in the alpine, and is concentrated in gullies. No new precipitation received in the past 48 hours. Cougar Creek and Three-Sisters creeks are flowing normally for this time of the year. The Bow River flow is within its normal range for early June. Groundwater levels are close to their historical highs, which is our main concern at this time. Many properties are now pumping water, a small amount of precipitation could create ponding issues as our storm drainage won't be able to manage new water influx.

Flooding can occur at any time with little to no warning. May 15 to July 15 is when we receive our largest rainfalls and are most likely to experience flooding. Understand, prepare and stay informed by knowing your flood ​risk and how to prepare for flood conditions.

Previous Updates

June 7: Some concerns in the one-week forecast. The snowpack in the Bow River Watershed is within the normal seasonal range for this time of year. The rapid melting that occurred last week has stopped, due to cooler temperatures.

June 4:  Alberta Environment has declared a Flood Watch for upstream of Banff (https://bit.ly/3po30aP ). Recent warm weather is melting snowpack upstream and raised water levels in streams and the Bow River basin. Forecasted rain will also increase the flow rate and level. The Bow River in Banff and Lake Louise is currently above average after rising 0.4m to 0.5m since June 1 and is expected to further rise 0.2 to 0.4 m over the weekend. Water levels for Pipestone River near Lake Louise may also rise 0.15m to 0.30m. Please respect all barriers and avoid flooded trails. Avoid riverbanks as they can be slippery and dangerous beside fast-moving water with significant debris. Avoid river recreation.
