Watershed Conditions Statement – Water Safety

Watershed Conditions Statement – Water Safety

March 5, 2025

Maitland Conservation has issued a Watershed Conditions Statement – Water Safety for all municipalities in the Maitland and Nine Mile River watersheds.

A large Colorado Low began to affect the region Tuesday morning, bringing warmer temperatures and widespread light rain to Southern Ontario. Temperatures are forecasted to continue to climb today, reaching a high of 9℃ by this afternoon. As of this morning, the watersheds had received approximately 10 to 15 mm. Light rain is anticipated to continue before transitioning back to snow by Thursday morning. The combination of warm temperatures and rainfall are expected to cause a minor melt of the snowpack and result in 15-20 mm of runoff. The melt will be brief with temperatures quickly falling back below zero overnight.

Significant flooding is unlikely; however, water levels may approach bankfull, leading to minor ponding in typical low-lying areas. As water levels rise, river ice will weaken, but a major breakup of ice is not expected.

Municipal officials are encouraged to check drainage systems and monitor low-lying and flood prone roads. We remind people that slippery and unstable streambanks and cold-water temperatures will create hazardous conditions around all watercourses. River ice will be extremely unstable and dangerous.

The snowpack is expected to retain most of its water content and flood potential will remain high as we continue into March. Maitland Conservation is monitoring watershed conditions and will provide an update if warranted.

This message is in effect until the afternoon of Monday March 10, 2025.

Types of Flood Messages:

Watershed Conditions Statement – Flood Outlook – Early notice of the potential for flooding based on weather forecasts calling for heavy rain, snow melt, high wind or other conditions that could lead to high runoff, cause ice jams, lakeshore flooding or erosion

Watershed Conditions Statement – Water Safety – General watershed conditions are being assessed for high runoff potential that could lead to flooding, and to remind the public of general river safety issues.

Flood Watch – Flooding is possible in specific watercourses or municipalities. Municipalities, emergency services and individual landowners in flood-prone areas should prepare.
