Flood Watch
Flood Potential: High
Issued to: local municipalities and school boards, local conservation authorities, emergency response agencies, health unit, media, NVCA board and staff
Date April 15, 2026 (9:30 AM)
The Nottawasaga Valley Conservation Authority (NVCA) advises an upgrade from a Flood Outlook to a Flood Watch.
A major low-pressure system continues to travel across the watershed, which will continue to bring heavy rain to the watershed. The next 48 hours will bring further rainfall accumulations of 15-30 mm. Locally higher rainfall totals are possible, particularly in areas that are impacted by thunderstorms.
Soil in the watershed is currently saturated and water levels along the Nottawasaga River and its major tributaries are elevated and continue to rise. At several locations water levels are exceeding the top of the bank. The risk of localized flooding will persist, especially if new thunderstorms form.
Elevated water levels from rainfall and runoff will continue to make local streams and rivers hazardous, particularly near culverts, bridges, and dams. Watercourses will continue to be high and fast flowing for the next 72 hours, and banks may be slippery. The public is urged to exercise caution and avoid all watercourses, especially for the safety of children and pets.
Nottawasaga Valley Conservation Authority staff will be monitoring the situation closely and will provide an update if conditions change. This Flood Watch will be in effect until (or updated before) end of day Sunday, April 19th, 2026.

A Flood Watch is a notice that the potential for flooding in the near future exists in specific watercourses and municipalities. Flood Watches may be issued when stream conditions and weather are expected to produce flooding.
