Update: 5:00 p.m. Wednesday, May 16, 2018

Alberta Environment and Parks has just posted a high streamflow advisory for the Bow River:

Advisories apply to streams and their tributaries unless otherwise noted.

  • Snowmelt has increased water levels in the Pipestone River near Lake Louise and the Bow River upstream of Calgary, causing the flooding of low-lying areas.
  • The Pipestone River has risen 0.3 m in the last week and is approaching levels observed last year which resulted in the closer of a trail and picnic area by Parks Canada.
  • The Bow River at Lake Louise and at Banff has risen approximately 0.5 m in the last week. The Town of Banff may close the walking trails west of downtown in the next few days.
  • The Town of Canmore has closed the pathway under the Bow River bridge with additional closures possible over the next few days.   
  • The cooler temperatures forecast over the next two days are expected to slow the mountain snowmelt.  However, the 10-30 mm of precipitation forecast through Friday has the potential to cause additional water level increases along the Bow River and its tributaries.  There are no significant flooding concerns at the time. However, the situation will continue to be monitored and additional advisories will be issued as required.

Forecast Precipitation - Between Wednesday afternoon and Friday morning up to 40 mm is forecast for the Bow Valley west of Calgary with lesser amounts to the south and north. Isolated amounts of up to 50 mm are possible in the form of localized convective precipitation. The heaviest amounts are expected on Wednesday evening.

Alberta Environment and Parks is in close contact with weather forecasting agencies, including Alberta Agriculture and Forestry and Environment Canada.

The Bow River level has been rising steadily over the last few weeks. It is within normal yearly range; however it is slightly higher than its normal range for mid-May. Groundwater levels are rising and some areas in valley bottom might become affected in the next days. 

Update: 9:30 a.m. Monday, May 7, 2018

The mountain snowpack generally melts gradually, as warmer temperatures climb in elevation over the course of the spring and summer, and are not expected to cause river related concerns with rapid snowmelt alone. No significant water level rises are expected in the major rivers at this time due to snowmelt. The debris net on Cougar Creek was closed on May 3.

Update: 8:30 a.m. Thursday, May 3, 2018

Temperatures are forecasted to be in the high 10s for the next several days with little precipitation forecasted until Sunday night. This will promote snow melt in all the creek catchments. The current snow depth in Cougar Creek, at tree line, is around 46cm, 4cm less than on Monday. Some creeks have been flowing due to the snow melt and the rain of the last week. Depending on temperatures, some creeks may flow in the afternoons. The Bow River flow is still within average for early May.

Update: 9:30 a.m. Tuesday, May 1, 2018

The Town of Canmore has received 10mm of rain in the last 48 hours with cooler temperatures. The rain fell as a mix of rain and snow at higher elevation with a measured 10cm of new snow at tree line in the Cougar Creek catchment. The current snow depth in Cougar Creek, at tree line, is around 50cm - which is 20cm less than a week ago. Some creeks have been flowing due to the snow melt and the rain of the last few days. The Bow River flow is still within average for early May. 

Update: 11:00 a.m. Monday, April 23, 2018

High temperatures are forecasted for the Bow Valley this week which will increase the snowmelt. The current amount of snow in the Cougar Creek watershed is currently similar to 2017 levels at treeline. There is a higher amount of snow at lower elevations compared to previous years. Some creeks might be flowing in the afternoons. The Bow River flow is within average rates for this time of year. The Town of Canmore will increase its monitoring in the coming weeks, according to the forecasted weather.
