RVCA Watershed Conditions Statement:  Minor low water conditions continue in Rideau Valley watershed

September 5, 2019 – Valley watershed Despite recent cool and rainy weather, a Minor Low Water status remains in place for the Rideau Valley Watershed under the Ontario Low Water Response Program.

Watershed residents and businesses are encouraged to conserve water during dry conditions.

Temperatures have fallen in recent days and rainfall has increased, but the average 90-day rainfall measured at climate stations in and around the Rideau Valley Watershed remains below 80 per cent of normal for this time of year, which is a key indicator for Minor Low Water status.

In the past 30 days, average rainfall has been just above 80 per cent of normal. Looking ahead, the seven-day weather forecasts suggests we’ll experience normal temperatures and possibly some small amounts of rain.

For the most part, water levels in lakes and rivers are close to normal for this time of year, and this is expected to continue into the fall with lwer evaporation rates compared to those of the warmer summer months.

Conservation Authority staff continue to monitor conditions and communicate with water managers throughout the watershed. Updates to this message will be issued as conditions warrant.
