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.
