Sampling Program

Launched in 2022, this major project requires significant time and financial resources to collect, compile, analyze, and interpret the results of the numerous water samples taken throughout the watershed and in Lake Davignon.

Water Quality Sampling Program for the Watershed and Lake Davignon

Certainly one of the most important projects for the CSBVLD, the water quality sampling program for Lake Davignon and its watershed has required numerous volunteer hours as well as a significant financial investment.

Why conduct a water sampling program?

The most direct benefit is knowing the quality of the water that users of Lake Davignon and its watershed encounter daily. Comparative analysis with previous data (dating back 10 years) allows us to evaluate the environmental impacts of changes that have occurred within the territory.

The study of different sectors of Lake Davignon's tributaries allows us to target the most problematic areas requiring priority intervention to protect water quality. These tributaries include:

Yamaska South-East River
Jackson's Creek
North Branch Creek
Marsh Creek

Finally, this monitoring fits within Lake Davignon Watershed Water Master Plan (2018). (Plan directeur de l’eau du bassin versant du lac Davignon (2018).

The sampling program, which began in 2022, continued this year. The results were presented during a meeting of regional stakeholders and will be presented publicly during the CSBVLD General Assembly on April 2, 2025. A copy of the analysis is available below.

Thank you to the many financial partners of this major project.

Significant Financial Support of $25,000 for Water Protection

Guy St-Louis, a Cowansville businessman and Lake Davignon waterfront resident, is showing his support for the CSBVLD with a major donation of $25,000.

Water protection is a major issue. Guy St-Louis is well aware of this and is taking concrete action by contributing financially. This year (2023), a portion of this amount will be invested in the water quality sampling campaign for the watershed and Lake Davignon.

Our donor hopes that his gesture will have a snowball effect and that other local businessmen and women will mobilize to support the CSBVLD.

The compilation, analysis, and interpretation are now complete.

The scientists from the Yamaska Watershed Organization (OBV Yamaska) were tasked with preparing and submitting a final report to the CSBVLD in early 2024.

The collected data were compared with that from 2010-2011 (a sampling campaign at the same stations was conducted more than ten years ago). Since construction work has taken place in the area since then, the analysis determined whether this work has had an impact on water quality.

Here is a copy of the report. It will be presented by a guest speaker at the CSBVLD Annual General Meeting on April 2, 2025, at the Arthur Fauteux Hall in the Brome-Missisquoi MRC
