Warm temperatures raise Bow River levels, High Streamflow Advisory issued in Banff

Rapid snowpack melt caused by warm weather in Banff and surrounding mountain regions has pushed water levels higher along the Bow River, prompting the Town of Banff to issue a High Streamflow Advisory.

Municipal officials said several low-lying pathways and riverbank areas have already been flooded as water levels continue to rise. According to the advisory, the Bow River could rise by an additional 30 centimetres by Friday if warm temperatures persist.

The advisory applies to areas from upstream of Banff to the Ghost Reservoir. Lake Louise RCMP and Parks Canada have also issued public safety warnings related to fast-moving water conditions in the region.

The Town of Banff and the Town of Canmore said on social media that residents and visitors should avoid flood-prone areas, riverbanks, and low-lying trails until conditions improve. Authorities warned that fast-flowing water can pose serious safety risks.

The advisory is significant for residents and tourists across the Bow Valley as spring snowmelt accelerates in the Rocky Mountain region. Officials said conditions continue to be monitored and additional updates may be issued if water levels increase further.
