NEWS RELEASE
NOTTAWASAGA VALLEY CONSERVATION AUTHORITY
************************
Flood Potential: High

Ice Jam Potential: Moderate

Issued to: local municipalities and school boards, local conservation authorities, emergency response agencies, health unit, media, NVCA board and staff

Date March 15, 2025 (4:10 PM) – Extended March 17, 2025

The Nottawasaga Valley Conservation Authority advises that a Flood watch Statement is in effect.

Weather Conditions

The Ministry of Natural Resources and Environment, along with Climate Change Canada, advises that a major low-pressure system will continue to move across the watershed this afternoon, into tonight, and through Monday bringing further rainfall accumulations of 15-20 mm and periods of warmer temperatures exceeding 10°C. These conditions, combined with the existing snowpack, are expected to cause significant snowmelt, resulting in increased runoff, with peak flows anticipated now through Monday.

Due to frozen ground conditions, rain and runoff absorption will be limited, increasing the risk of localized flooding in low-lying areas and ponding on roadways. Elevated water levels from rainfall and runoff will also make local streams and rivers hazardous, particularly near culverts, bridges, and dams. The public is urged to exercise caution and avoid all watercourses, especially for the safety of children and pets.

NVCA will continue to closely monitor weather conditions, ice formation, and water levels within the watershed. The Watershed Conditions Statement for Flood Watch will remain in effect until the end of Tuesday, March 18, 2025, or until further notice.

Issues

Water levels are currently elevated as a result of heavy rainfall, warm temperatures, and snow melt. A significant amount of rain is forecast to continue today and into Sunday.

Water may overflow banks and cause flooding in some areas. Widespread flooding is not anticipated at this time, but low-lying and flood-vulnerable areas may be impacted.
