September 5, 2019 – 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 lower 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.

October 30, 2019 —This statement is to advise that the “Minor Low Water” status in the Rideau Valley Watershed is returned to “Normal’ under the Ontario Low Water Response Program.

With several significant rainfall events occurring during the last two weeks, the average 90-day rainfall measured at climate stations in and around the Rideau Valley Watershed is well above 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 greater than 100 per cent of normal. Looking ahead, the seven-day weather forecasts suggests we’ll continue to experience more rain, including a large rainfall event tomorrow.

Water levels in some of the smaller rivers and streams across the watershed were well below normal prior the significant rainfall events noted above. These water levels have now begun to increase, and this trend is expected to continue based on the weather forecast.

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.

June 4, 2020 – Due to below average rainfall in April and May, conditions in the Rideau Valley Watershed now meet the threshold for Minor Low Water status under the Ontario Low Water Response Program. Watershed residents and businesses are encouraged to conserve water during dry conditions.

Although stream flow values are not currently below any of the low water thresholds, the stream flow values are lower than normal by as much as 30 to 50 percent and field observations indicate that ecological conditions are becoming stressed. The average 90-day rainfall measured at climate stations in and around the watershed is just shy of 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 is slightly below 50 per cent of normal. Looking ahead, the seven-day weather forecast suggests we will continue to receive minimal precipitation.

Following an early spring freshet this year, Parks Canada are closely monitoring the water levels throughout the Rideau Canal system inside the Rideau Valley watershed. Water levels in the reservoir lakes are currently close to normal but are expected to decline with little precipitation in the short-term forecast. Rideau River flows downstream of Big Rideau Lake have been reduced to minimum. Water levels in the Rideau River below Smiths Falls are within navigable ranges.

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.

June 25, 2020 – This statement is to advise that the low water status in the Rideau River watershed is now at MODERATE severity under the Ontario Low Water Responses Program.

Although some areas of the watershed have received more rain than others, the watershed has received very little rainfall over the past three months. The average 90-day rainfall measured at climate stations in and around the watershed is below 80 per cent of normal for this time of year. In the past 30 days, average rainfall is well below 50 per cent of normal. Looking ahead, the seven-day weather forecast suggests we will continue to receive minimal precipitation.

Stream flow values for all waterways are well below normal for this time of year. For example, the measured flows for the Rideau River at Carleton University and the Tay River in Perth are at about 40 percent normal for this time of year. Measured flows for the smaller tributaries such as the Jock River and Kemptville Creek are near 5 percent of normal for this time of year. Field observations around the watershed indicate that ecological conditions are poor with many fragmented streams and numerous reports of algae and/or weed growth.

Following an early spring freshet this year, Parks Canada are closely monitoring 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 below normal and are expected to decline further with little precipitation in the forecast. Rideau River flows downstream of Big Rideau Lake have been reduced to minimum. Water levels in the Rideau River below Smiths Falls are within navigable ranges but some areas are below average for this time of year.

Water conservation is encouraged for all watershed residents and businesses, especially 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 Ottawa River. Residents throughout the watershed should be aware of any bans or bylaws that may be in place in their municipalities regarding fires or watering bans.

Conditions are expected to decline with limited rain in the forecast. 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.
