High streamflow advisory issued for the Bow River
(Cochrane, AB) – Water levels on the Bow River are expected to rise significantly over the coming days due to increased snowmelt and forecasted rainfall. A high streamflow advisory is in effect from upstream of Banff to Ghost Reservoir.
Residents are urged to use extreme caution near the river and avoid flooded areas, pathways and riverbanks. Fast-moving water, submerged debris, slippery banks and unstable embankments create dangerous conditions. What may appear to be solid ground can be undercut by water. Keep children and pets away from the water's edge and respect any pathway closures resulting from overland flooding.
Watercraft use on the Bow River is not recommended at this time.
If an emergency occurs on or near the river, call 911 immediately. Do not enter the water or attempt a rescue.
Neighbourhood stormwater management & water pooling
With rainfall expected in the coming days, residents may also notice water pooling on roads, lanes, driveways and greenspaces. In many cases, this is normal and unrelated to rising river levels.
Some neighbourhoods are located near trap lows, which are designed as part of Cochrane's stormwater management system. These areas temporarily store runoff during heavy rain events, allowing water to collect on streets and nearby greenspaces while directing it safely away from homes and foundations. While water may appear to extend onto portions of driveways or lawns, trap lows are functioning as intended.
If standing water has not drained within 24 hours after rainfall ends, please contact Cochrane Operations at 403-851-2590. To find out if your property is located near a trap low, visit cochrane.ca/traplows.
