Update 1: June 2, 2026 | 3:40 p.m.
A High Streamflow Advisory remains in effect for the Sheep River basin. The Sheep River has increased by 1.17 m since Sunday and is currently flowing at 163.61 m³/s. Latest projections suggest levels will begin to taper.
We remain in Stage 1 (High Stream Advisory) of our Emergency Management Plan and are closely monitoring river levels, with the ability to move to Stage 2 (Flood Watch) quickly if needed. Residents are asked to stay clear of the river and surrounding areas while water levels are high and fast-moving. Conditions can change quickly. Riverbanks may become unstable, and debris may be dislodged and carried downstream.

A special weather statement has been issued from Environment Canada for central and south Alberta for strong winds, heavy rain and colder temperatures. Heavy rain is expected to continue through to Wednesday morning, with total amounts of 50-100 mm and a possible river flow rate of 65-150 m³/s.
As of today, the Town has activated Stage 1 (High Stream Advisory) of our Emergency Management Plan in response to the high streamflow advisory currently in effect for the Sheep River. A high streamflow advisory occurs when stream levels are rising or expected to rise rapidly and no major flooding is expected. Minor flooding in low-lying areas is possible.
While there is no immediate threat to public safety, stage one reflects our commitment to preparedness. The emergency management team is actively monitoring conditions, coordinating with regional and provincial partners, and ensuring readiness in case the situation changes.
Heavy rainfall may also overwhelm storm drains and lead to overland flooding, especially in low-lying areas. As a precaution, residents are reminded to:
- Clear eavestroughs and downspouts.
- Direct water away from foundations.
- Watch for pooling water in low-lying areas of your property. If you’d like to add extra protection, free sandbags are available for pickup at the Okotoks Operations Centre parking lot (1118 N Railway St). Please be mindful and leave some for your neighbours.
- Check sump pumps and backflow valves.
- Stay away from riverbanks and fast-moving water, as riverbanks can become unstable and water conditions can change rapidly during high streamflow events.
