(WCS – R13/2023)
August 10, 2023 – Caution is advised around all waterways in the Rideau Valley Watershed following several large rain events over the last few weeks, with additional rain in the forecast. Observed rainfall amounts for the last month across the watershed are significantly more than normal. Environment Canada’s short-term weather forecast indicates we may receive an additional 50 to 100 mm of rain over the next 7 days.
Water levels and flows in all waterways are generally higher than average for this time of year across the Rideau Valley Watershed. Although no significant riverine flooding is anticipated, water levels and flows are expected to remain seasonally high in all waterways in the Rideau Valley Watershed over the next week.
Until the water levels and flows recede, the RVCA advises the public to exercise extreme caution around ALL WATERBODIES AND DAM STRUCTURES and remind children about the dangers of playing near open water. All boaters and swimmers using the Rideau River and other larger water bodies are advised to exercise extreme caution due to much higher flows than normal over the next few days.
This watershed conditions statement is in effect until Friday, August 18, 2023 at 5 PM or until an update has been issued.
