(WCS – R08/2024) - The Rideau Valley Conservation Authority is issuing a WATER SAFETY message for the entire Rideau Valley Watershed.
A low-pressure system associated with remnants of Tropical Storm Debby is expected to produce heavy rainfall throughout the region. Local estimates of 50 to 100 mm of rainfall are possible beginning Thursday evening and continuing into Friday. Despite above normal precipitation over the last month, stream flows have generally stabilized at normal seasonal levels.
Although riverine flooding is not anticipated at this time, all water levels and flows across the Rideau Valley Watershed are expected to increase. Depending on the location and rainfall intensity, localized flooding in low-lying areas, including ditches and stormwater features, may be possible. Flows on the Rideau River are not expected to increase significantly.
It is advised that residents adjacent to smaller tributaries and streams take precautionary measures to protect their property, including:
- Ensuring sump pumps are clear, in good working condition and have a backwater valve
- Ensuring easy access to a portable backup generator and pump
- Ensuring downspouts are clear and the outlet is at least 3 metres from the dwelling
- Securing items that might float away as flows increase
Until the water levels and flows recede, the RVCA advises the public to exercise extreme caution around ALL WATERBODIES and remind children about the dangers of playing near open water.
This watershed conditions statement is in effect until Friday, August 16, 2024 at 5 PM or until an update has been issued.
