Watershed Conditions Statements

(WCS – R03/2024)February 26, 2024 – Unseasonably warm temperatures combined with significant rainfall is expected to trigger a widespread melt across the Rideau Valley Watershed this week. Temperatures are expected to rise significantly on Tuesday, February 27 and last until Thursday, February 29, with daily highs exceeding 10°C. Widespread precipitation is also expected during this period, with forecasts estimating between 20 and 30 mm of rainfall. Although snow conditions are considered below normal for this time of year, the warm temperatures and added rain will trigger an accelerated melt. Beginning on Tuesday, water levels and flows are expected to increase in all…
(WCS – R02/2024) February 9, 2024 – Caution is advised as above normal temperatures are forecasted for the Rideau Valley Watershed this weekend. Environment Canada’s short-term weather forecast indicates above-zero temperatures approaching 10 degrees Celsius on Friday and Saturday. On Sunday and Monday, the temperatures are forecast to approach 5 degrees Celsius before cooling off to more seasonal below-zero temperatures next week. Less than 5 mm of precipitation is expected on Friday and Saturday.  Water levels and flows are generally average for this time of year across the Rideau Valley Watershed.

(WCS – R01/2024)January 15, 2024 – The Rideau Valley Conservation Authority is issuing a WATER SAFETY message for the entire Rideau Valley Watershed due to the potential for localized ice jams which could cause sudden water level increases and flooding. Following a period of warmer than usual temperatures and then a significant snowstorm, Environment Canada is forecasting cold temperatures, as low as -20°C overnight, for the next week with little precipitation. The forecast also indicates sustained winds are expected, which will cause wind chill temperatures. Many waterways are not yet frozen and with the onset of colder weather, there is a potential in localized…
(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.

(WCS-LW - 2/2023)August 9, 2023 – Watershed conditions in the Tay River and Rideau Lakes watersheds have returned to “Normal’ under the Ontario Low Water Response Program. However, the water levels in Bobs and Christie Lakes, which are used throughout the recreational season to augment the flow in the Tay River and regulate navigation in the Rideau River, are still below average for this time of year.  Parks Canada staff continue to closely monitor these lakes and expect the water levels to approach normal levels with rain in the forecast. With well above-average rainfall amounts across the watershed during the last…
(WCS-LW - 1/2023)July 11, 2023 – Following a period of dry and hot weather, the Rideau Valley Low Water Response Team is declaring a MINOR low water status for the Tay River and Rideau Lakes watersheds (referred to as Upper Rideau Valley watershed), after officials met to discuss current watershed conditions on Monday, July 10, 2023. Upper Rideau Valley watershed residents and businesses are encouraged to voluntarily reduce their water usage by 10 percent.
