RIDEAU VALLEY, February 5, 2024 – A new detailed analysis from the Rideau Valley Conservation Authority (RVCA) has found many parts of the Rideau River Watershed are changing fast – and not always with positive results. 

The RVCA’s 193-page Watershed Conditions Report is the first of its kind in more than 50 years. It compiles recent and historical monitoring data to assess trends regarding surface and ground water quality, aquatic ecosystem health, hydrological function, natural hazard risks and the status of critical green infrastructure such as wetlands, forests and natural shorelines.

The analysis found several concerning trends including a continuing steep decline in large woodland patches, increasing chloride levels in our urban streams, and large shifts in surface water flow patterns linked to increased development and loss of wetlands. 

The report also identifies knowledge gaps for natural hazard risks such as flooding, erosion and landslides in some parts of the watershed, as well as gaps in robust groundwater quality monitoring in rural communities where private wells are the most common source of drinking water.

“This document will provide invaluable insights for the RVCA and its partners as we continue to strive for balance between conserving our natural resources and helping build safe and thriving communities,” said RVCA General Manager Sommer Casgrain-Robertson. “The issues identified here do not come as a surprise, but now we have data and analysis that will allow us to take targeted action and make measurable improvements for the benefit of all.” 

Completion of the conditions report is the first step in the development of a Watershed Management Strategy, which aims to identify areas of concern and then create a strategy to address them. This process will include public consultation later in 2024. 

“We look forward to partnering with First Nations, our member municipalities,  partners, stakeholders and the public to develop a strategy that promotes prosperity and health for the entire watershed for generations to come,” Casgrain-Robertson said.

(WCS – R01/2024)
January 15, 2024 – The Rideau Valley Conservation Authority is issuing a WATER SAFETY message for the entire Rideau Valley Watershed due to the potential for localized ice jams which could cause sudden water level increases and flooding.

Following a period of warmer than usual temperatures and then a significant snowstorm, Environment Canada is forecasting cold temperatures, as low as -20°C overnight, for the next week with little precipitation. The forecast also indicates sustained winds are expected, which will cause wind chill temperatures. Many waterways are not yet frozen and with the onset of colder weather, there is a potential in localized areas for ice to form quickly, especially on water structures such as bridge abutments, piers, riverbanks, and channels. This could obstruct the flow of water and cause local water levels to rise. Any sudden water level increases may cause localized flooding. Parks Canada, which manages water levels for the Rideau Canal waterway, is also undertaking necessary dam operations in some areas which may increase the potential for rapid ice formation during this cold spell. 

Residents are advised to stay away from all rivers and watercourses in the vicinity of any ice jams and high water areas.  Parents are encouraged to explain these dangers to their children.

This watershed conditions statement is in effect until Thursday, January 25, 2024 at 5 PM and may be updated at that time unless the forecast or conditions change.

"Rideau Valley Conservation Authority is a partnership of municipalities within the Rideau Valley watershed 
created under the Conservation Authorities Act to deliver a range of programs in watershed management and
natural resource conservation."

RVCA Watershed Conditions Statements: 

• Water Safety – High flows, unstable banks, melting ice or other factors that could be dangerous for recreational users such as anglers, canoeists, hikers, children, pets, etc. Flooding is not expected.
• Flood Outlook – Early notice of the potential for flooding based on weather forecasts, calling for heavy rain, snow melt, high winds or other conditions that could lead to high runoff, cause ice jams and/or lakeshore flooding or erosion.
• Flood Watch – Flooding is possible in specific watercourses or municipalities. Municipalities, emergency services and individuals in flood prone areas should prepare.
• Flood Warning – Flooding is imminent or already occurring in specific watercourses or municipalities.
