MAY 31, 2019 — Rideau Valley Conservation Authority (RVCA), in conjunction with the Mississippi Valley Conservation Authority (MVCA) and South Nation Conservation (SNC) is TERMINATING the FLOOD WARNING issued on April 19, 2019 for the areas under our jurisdiction along the Ottawa River.

Watershed Conditions – High Water Safety message is in effect as all areas are still well above normal for this time of year and conditions are expected to remain that was for at least the next two weeks.

The most recent analysis from the Ottawa River Regulation Committee (ORRC) indicate that water levels along the lower Ottawa River from Chats Lake to the Grenville/Hawkesbury area are declining steadily and that trend is expected to continue.

Residents are advised to stay away from watercourses where flows are high and where banks might be unstable. Parents are encouraged to explain dangers to children.

The Watershed Conditions – High Water Safety message will remain in effect until Friday, June 7, 2019 at 5:00 PM. No further updates will be issued unless forecasted levels or conditions change.

RVCA and its Ottawa partners, MVCA and SNC monitor the water levels and weather forecasts with the Ministry of Natural Resources and Forestry as part of the Flood Forecasting and Warning Program.

The Ottawa River Regulation Planning Board will be reassessing forecast conditions and providing hydrological condition updates on its website daily at
