(WCS-LW - 3/2020) July 15, 2020 – This statement is to advise that the low water status in the Rideau River watershed continues to be at MODERATE severity under the Ontario Low Water Responses Program.

Although varying amounts of rain fell across the watershed last weekend, the watershed has still 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 60 per cent of normal for this time of year. In the past 30 days, average rainfall is below 45 per cent of normal. The recent hot weather has also increased the evaporation rates throughout the watershed. Looking ahead, the seven-day weather forecast suggests we may receive over 20 mm of rain.

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 50 percent normal for this time of year. Measured flows for the smaller tributaries such as the Jock River and Kemptville Creek are at or below 3 percent of normal for this time of year. Field observations around the watershed indicate that ecological conditions are poor and declining with many fragmented streams, warm temperatures and numerous reports of extensive algae and/or weed growth.

Members of the Rideau Valley Water Response Team have indicated that municipal water supplies are not experiencing any issues as a result of low water and no issues with private wells have been reported. However, the Ontario Ministry of Agriculture and Food (OMAFRA) indicate numerous concerns including loss of crop yields and increase in wells being drilled to supply water for livestock.

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 limited 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.

Watershed residents and businesses are encouraged to voluntarily reduce their water usage by 20 percent and strongly encouraged to limit non-essential water usage. 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 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.

In order that RVCA can track impacts of the low water conditions in the watershed, its is requested that any individuals or businesses in the Rideau Watershed who may be experiencing difficulties with their wells or other low water impacts please contact the Conservation Authority by email. Please send emails to .

Although there is some rain in the forecast, low water conditions are expected to intensify in the coming weeks. 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.

(WCS-LW - 4/2020) August 5, 2020 This statement is to advise that the low water status in the Rideau River watershed is being downgraded to “Minor” from “Moderate” severity under the Ontario Low Water Response Program because of recent precipitation.

Significant rain over the last week pushed 30-day rainfall totals above what is normal for the time of year at most climate monitoring sites in the region. However, 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 which represents “Minor” low water severity. Looking ahead, the seven-day weather forecast suggests we may receive between 5 and 10 mm of rain across the watershed.

Stream flow values for all waterways are much closer to normal for this time of year compared to a few weeks ago. For example, the measured flows for the Rideau River at Carleton University and the Tay River in Perth are both slightly above 100 percent normal for this time of year. Measured flows for the smaller tributaries such as the Jock River and Kemptville Creek are still below normal for this time of year. Field observations around the watershed indicate that ecological conditions are much improved compared to a few weeks ago. 

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. 50-75% lower than normal amounts of precipitation in June and July resulted in below average level and flows conditions across the entire watershed. However, due to the recent significant rainfall received around the reservoir lakes (located in upper part of the watershed), the reservoir lake levels are near and/or above average. Due to the localized nature of the rain events, other nearby lakes located in the upper reaches of the Rideau Valley watershed, remain below normal. 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.

Watershed residents and businesses are encouraged 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 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.

(WCS-LW - 52/2020) September 2, 2020 — Watershed conditions in the Rideau Valley Watershed have returned to “Normal’ under the Ontario Low Water Response Program.

With significant precipitation during the last month, the amount of rainfall received throughout the watershed is at or above average values for this time of year. As a result of this precipitation, stream flows and water levels are now at or above average values for this time of year. Looking ahead, the seven-day weather forecasts suggests we’ll continue to receive more rain.

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 either normal or above normal (i.e., Christie Lake) for this time of year and are expected to decline but this will depend on rainfall amounts received in the coming weeks. Rideau River flows downstream of Big Rideau Lake are now near normal. Water levels in the Rideau River below Smiths Falls are within navigable ranges for this time of year.

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.

(WCS-LW - 1/2021) June 8, 2021 — Due to below average rainfall over the last three months, 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 by limiting non-essential uses (e.g., lawn watering, car washing, etc.), for an overall consumption reduction of about 10 percent. 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 indicate that ecological conditions are becoming stressed. The average 90-day rainfall measured at climate stations in and around the watershed is near 60 per cent of normal for this time of year, which has triggered the Minor Low Water status. In the past 30 days, rainfall has been variable across the watershed, with the average amount being near 35 per cent of normal. Looking ahead, the seven-day weather forecast indicates we will receive minimal precipitation.

Following an early spring freshet this year, Parks Canada staff are closely monitoring the water levels throughout the Rideau Canal system inside the Rideau Valley watershed. Water levels in the reservoir/flow-through lakes are currently well below normal and are expected to decline further 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.

To better understand local conditions; landowners, businesses, and industries are encouraged to contact Brian Stratton by email () if they are experiencing any unusual water-related problems. 

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.

(WCS-LW - 2/2021) July 6, 2021 — The Rideau Valley Low Water Response Team is maintaining a MINOR low water status for the Rideau River watershed after officials met to discuss dry conditions on Tuesday, July 6.

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 Ottawa River. Residents throughout the watershed should be aware of any bans or bylaws that may be in place in their municipalities regarding watering or fires bans.

Significant rain over the past few weeks has pushed 30-day rainfall totals above what is normal for the time of year at most climate monitoring sites in the region. However, 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 which represents “Minor” low water severity. Stream flow values for all waterways are well below their normal values for this time of year but slightly improved from a few weeks ago. For example, the measured flows for the Rideau River at Carleton University and the Tay River in Perth are both near 45 percent of normal for this time of year. Measured flows for the smaller tributaries such as the Jock River and Kemptville Creek are still below normal for this time of year. Field observations around the watershed indicate that ecological conditions are declining with increased fragmentation of many streams.  High water temperatures, low oxygen levels and increased plant growth and are being experienced in many areas.

Looking ahead, the seven-day weather forecast suggests we may receive between 35 and 45 mm of rain across the watershed. These rainfall amounts are not expected to greatly improve the 90-day rainfall deficit or the low stream flow values discussed above.

Following an early spring freshet this year, Parks Canada staff are closely monitoring the water levels throughout the Rideau Canal system inside the Rideau Valley watershed. The water levels in the reservoir lakes (Bob’s Lake and Wolfe Lake) are currently slightly below normal and are expected to decline further with some precipitation in the short-term forecast. The water level in Christie Lake (flow-through lake), while expected to remain below normal, will fluctuate with some 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.
