The Raisin Region Conservation Authority (RRCA) is advising residents and landowners near rivers and creeks to be prepared for possible flooding during the spring melt this year.
The winter of 2018-19 has seen significant snow and freezing rain with some intermittent freeze-thaw cycles. The snow pack throughout the region as of early March was above average and was holding substantial water content. There is a potential for above average flooding this spring across the Raisin Region watershed, especially in low lying areas that have flooded in the past. There is also a concern for flooding along laneways and driveways due to snow/ice and debris accumulation within the ditches and culverts.
Additionally, this year’s cold winter has resulted in thicker than usual ice cover on the rivers; this can lead to ice jamming and ice piling as the rivers break up.
With the changing levels that can be expected over the coming weeks, ice cover on lakes, ditches, local streams and rivers will continue to be unstable.
Extreme caution should be exercised by everyone when near local water bodies. Parents should inform their children of the risks and provide appropriate supervision. Residents in flood prone or low-lying areas, historically susceptible to flooding, should take the necessary precautions to protect their property.
Ensure your sump pump is clear, in good working condition and has a backwater valve on it. Home owners should have a portable back-up generator and pump.
Ensure downspouts are clear and the outlet is at least three metres from the dwelling. Remove or secure items that might float away as flows increase.
Remove valuable items from basements or lower floors that could be subject to flooding.
Keep emergency phone numbers handy. Familiarize yourself with your municipality’s emergency preparedness plan.
The RRCA will continue to monitor conditions and will issue further statements when or if there is an indication that the situation can be expected to change significantly.
Flood forecasting and warning have been delegated to conservation authorities.
The Raisin Region Conservation Authority monitors precipitation and water levels throughout South Glengarry and Cornwall and large portions of North Glengarry and South Stormont.
