High streamflow advisory issued for the Bow River
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.
How to get prepared
- Avoid riverbanks and low-lying areas where the river can submerge pathways.
- Keep children and pets away - fast moving water can erode riverbanks quickly.
- If you live in a low-lying area that’s at risk of flooding, take steps to be flood ready; move valuables and documents out of your basement.
- Don't forget to check your sump pump and backflow valve if you have one.
- Check your swale for debris or blockages.
- Clean out downspouts and ensure they are pointed away from your foundation.
- Rainfall can lead to pooling water on local streets; when a significant amount of rainwater accumulates on a street, it is likely located near a trap low; these are devices that control water drainage from streets.
- Water may accumulate up to a homeowners’ driveway and part of their lawn, but it should completely drain within 24 hours once the rain stops.
Neighbourhood stormwater management & water pooling
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.
