Watershed Conditions Statements

(WCS – R02/2022)March 4, 2022 – Environment Canada is forecasting temperatures above 10 degrees Celcius and rain on Sunday. This weather event will likely result in elevated water runoff to all waterways because of snow melt and rainfall. 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,…
(WCS – R01/2022)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…
(WCS - RO6/2021)December 10, 2021 – Environment Canada is forecasting rainfall amounts of 20 to 40 mm starting the evening of Friday, Dec. 10 and continuing through Saturday night. This forecasted rainfall together with mild temperatures will melt snow and create runoff, causing all water levels and flows to increase throughout the Rideau Valley Watershed. Because of a wet fall season, most water levels and flows are currently above normal. Although this rain and snow-melt event will not cause significant flooding, it could cause localized flooding in small watercourses, urban areas and ditches.   The RVCA reminds the public to exercise extreme caution around all…
(WCS-LW - 5/2021)October 6, 2021 – Watershed conditions in the Rideau Valley Watershed have returned to “Normal’ under the Ontario Low Water Response Program. With above average rainfall amounts across the watershed over the last month, stream flows and water levels have recovered from the previous low water status and are now above average for this time of year. Parks Canada continues to closely monitor the water levels throughout the Rideau Canal system inside the Rideau Valley watershed. Water levels in the reservoir lakes, located in the upper reaches of the Rideau Valley watershed, are now near normal for this time…
(WCS – R05/2021)September 22, 2021 – Environment Canada is forecasting rainfall amounts of 60 to 90 mm starting today through early Friday morning, with a few localities possibly exceeding 100 mm. The higher amounts are forecasted for the upper part of the Rideau Valley Watershed. This widespread rainfall event is due to a cold front and a moisture-laden low pressure system that will arrive from the American Midwest. Because the Rideau Valley Watershed is currently in a ‘minor low water condition,’ all water levels and flows are currently below normal, so significant flooding is not expected. However, this large rain…
(WCS-LW - 4/2021) Sept. 8, 2021 —The Rideau Valley Water Response Team is maintaining a MINOR low water status for the Rideau River watershed after officials met to discuss conditions on Wed. Sept. 8. This low water status is a result of a warm and dry August. The August Weather Summary prepared by Environment and Climate Change Canada indicates that the average temperature at the Ottawa Airport was 2.4 °Celcius above normal and the monthly precipitation total was 57 percent of normal. Watershed residents and businesses are encouraged to voluntarily reduce their water usage by 10 percent. This is especially important for those who…
