Watershed Conditions Statements

(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…

Watershed residents and businesses are encouraged to continue to voluntarily reduce their water usage by 10 percent. This is especially important for those who have permits for taking water from surface or groundwater sources and all residents on private, communal or municipal wells. There is less of a concern for residents of urban Ottawa because the City of Ottawa central drinking water system draws from the…

Residents are also encouraged to consult with their municipalities regarding any water conservation bylaws that may be in effect. Stream flow values are lower than normal by as much as 20 to 30 percent and field observations…
Water Conditions Statement: Flood Outlook — Lower Ottawa River March 26, 2021 — A Flood Outlook Statement is being issued for areas along the Lower Ottawa River.
