RVCA - Precipitation and Mild Temperatures May Increase Water Levels

Precipitation, Mild Temperatures May Increase Water Levels and Flows and Cause Unstable Ice Across Watershed

February 16, 2022

Environment Canada is forecasting mild temperatures, with 15 to 25 mm of rain starting late today through Thursday afternoon followed by much cooler temperatures and possible snowfall accumulations of 10 to 20 cm of snow before mid-day on Friday. This weather event will likely result in elevated water runoff to all waterways because of snow melt and high rainfall amounts before freezing up again.

Although no significant flooding is anticipated, water levels and flows are expected to increase in all waterways in the Rideau Valley Watershed. Depending on how much snow melts and rain falls, residents who are adjacent to the smaller creeks and streams are advised to keep a close watch on water levels and flows and should take the necessary precautions to protect their property, such as:

•             Ensuring sump pump is clear, in good working condition and has a backwater valve

•             Ensuring easy access to a portable backup generator and pump

With the expected temperature changes and increase in water levels and flows in the coming days, ice cover on lakes, ditches, local streams and rivers will be unstable. Extreme caution should be exercised by everyone when near local waterbodies. Parents should inform their children of the risks and provide appropriate supervision.

This watershed conditions statement is in effect until Wednesday February 23, 2022 at 5 PM or until an update has been issued.
