Kingston – Cataraqui Conservation has issued a Watershed Conditions Statement today due to a strong storm system that is forecast to bring heavy rain and strong winds to the region Friday, December 10 and Saturday, December 11.
Rain is forecast to begin later in the day on December 10 and heavy rain will continue through the overnight into December 11. Forecasted rainfall totals are uncertain, ranging from 15 – 45 mm+. Environment Canada Special Weather Statements are in effect.
Some creek flows are still elevated following recent rainfall. With the current saturated or frozen ground conditions and minimal snowpack to absorb rainfall, high runoff into lakes and streams is expected, followed by water level and flow increases.
Water Managers, who operate dams on area inland lakes, are passing above-average flows through water control structures. Water levels on inland lakes and streams may rise for several days.
Cataraqui Conservation is urging caution around all dams (inflow and outflow channels) and fast-flowing watercourses. Respect the hazards in these areas by obeying all warning signs, and keeping 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 areas is possible, especially with the higher rainfall amounts. 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) Wednesday, December 15, 2021, at 11:59 PM.
