Caution Advised During High Water Season Across Rideau Valley Watershed

(WCS – R02/2025)

March 10, 2025 – The Rideau Valley Conservation Authority (RVCA) is issuing a Water Safety Statement for the duration of the spring freshet season, as fast-moving water, unstable banks, and melting or unstable ice may create hazardous conditions across the watershed. Caution is advised for all residents, especially anglers, boaters, hikers, parents and pet owners, to exercise caution near all waterways. While flooding is not anticipated at this time, residents should remain vigilant and avoid potentially dangerous areas around rivers, streams and other bodies of water.

Weather Forecast: Environment and Climate Change Canada forecasts consistent warm temperatures above 0°C over the next few weeks, with the possibility of concurrent rainfall.

Environmental Conditions: Current observations indicate that water levels and flows across the Rideau Valley Watershed are generally low and below average, with soils still frozen, reducing their ability to absorb water. Recent warming has contributed to increased snowpack density and, therefore, greater susceptibility to melting.

Risks: The forecasted warm temperatures will contribute to increased snowmelt and runoff, which may result in faster-flowing water, slippery or unstable banks, ice breakup, and potential flooding in low-lying areas.

Location-Specific Considerations: While significant flooding is not currently anticipated, all water levels and flows across the Rideau Valley Watershed are expected to increase. Depending on the location, localized flooding may be possible in low-lying areas, including ditches and stormwater features.

Action & Safety Recommendations: Residents are advised to exercise caution when near rivers, streams, and other waterbodies due to the risks summarized above. Parents should inform their children of these dangers and provide appropriate supervision.

Property owners in flood-prone areas should take necessary precautions, such as:

• Ensuring sump pumps are clear, in good working condition, and have a backwater valve.
• Keeping a portable backup generator and pump easily accessible.
• Ensuring downspouts are clear and directing water at least 3 m away from the dwelling.
• Securing items that could float away as water levels rise.

Duration: This Water Safety statement is in effect until Tuesday, April 15, at 11:59 pm or until an update has been issued.

RVCA monitors water levels and weather forecasts as part of its Flood Forecasting and Warning Program. Updates will be provided as conditions change.

Water Safety – High flows, unstable banks, melting ice or other factors that could be dangerous for recreational users such as anglers, canoeists, hikers, children, pets, etc. Flooding is not expected.

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

Flood Warning – Flooding is imminent or already occurring in specific watercourses or municipalities.

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