Cataraqui Conservation has issued a Watershed Conditions Statement – Water Safety today due to heavy rainfall expected August 8 - 10, the remnants of Tropical Storm Debby. Residents and visitors to the Cataraqui Region should exercise caution around water bodies.
Weather Situation: The remnants of Tropical Storm Debby are moving towards the Lower Great Lakes. With a forecasted range of 40 – 100 mm+ rainfall for August 8 - 10, quantity and intensity are expected to be very unpredictable. The bulk of the rain is expected August 9. Environment Canada Rainfall Warnings have been issued, forecasting 50 to 75 mm total rainfall and indicate the possibility of locally higher amounts.
Risks: Some streams will rise quickly, especially if the higher rainfall amounts are received and possible localized inundation of low-lying, poorly drained, and urbanized areas.
Increased discharge through water control structures at dams on managed lakes may result as Water Managers make adjustments to manage excess flows and limit, as much as possible, negative impacts.
Cataraqui Conservation is urging caution, particularly around all dams (inflow and outflow channels), fast-flowing watercourses, and stormwater ponds. Respect the hazards in these areas by obeying all warning signs, and keep away from booms, buoys, and barriers. Stay well back from the water’s edge above and below dams and hydroelectric stations. Creek banks and lake shorelines may be slippery, increasing the chance of falling in.
Widespread flooding is NOT expected at this time. However, localized inundation of low-lying and poorly drained areas is possible. If you witness flooding and/or require assistance, your first point of contact is the local municipality.
Staff will continue to monitor conditions and forecasts and will update statements as needed. This Watershed Conditions Statement will remain in effect until (or updated before) Monday, August 12, 2024, at 11:59 PM.
