Overview
- City officials said river levels were expected to crest by Tuesday and warned that Calgary flows have exceeded the boating-advisory threshold of 280 m3/s with recent readings above 360 m3/s.
- Environment and Climate Change Canada issued a rainfall advisory for Calgary calling for 50 to 100 mm of rain with pockets over 100 mm and said the heavy rain will taper to showers with an additional 5 to 10 mm possible.
- Municipal and utility operators lowered Glenmore and TransAlta’s Ghost reservoirs to create extra storage and deployed sandbags, pumps and a temporary dam device to protect vulnerable sites.
- Canmore has reported localized flooding of commercial and residential structures that require continuous pumping, and Banff has closed low-lying trails and parks while staging protective measures without ordering evacuations.
- Hydrologists and officials say current flows remain well below the 2013 flood peaks and that about $1.3 billion in post‑2013 flood investments in reservoirs, barriers and erosion protection have cut roughly 70% of the earlier damage potential.
