​​​​​​​​​​​​​​​​​​​​​​​​​​​​​Watershed Health Checks​

NVCA has produced nine subwatershed health checks and one watershed-wide health check in 2018. The health checks subwatershed health checks provide an overview of forest, wetlands, stream and groundwater health within the larger NVCA watershed. They also identify stewardship priorities, future challenges and opportunities to improve environmental health. 

Our science monitoring staff collects samples from forests, wetlands, streams and groundwater for data analysis. Our stewardship staff uses this information to determine the success of past restoration projects and areas in need of improvement.

NVCA is one of 36 Conservation Authorities across Ontario and is a proud member of Conservation Ontario​. Our watershed is approximately 3,700 km2, with jurisdiction in 18 municipalities and is the source of watercourses that flow into Georgian Bay at Wasaga Beach, Collingwood and Severn Sound.

​2007 - 2012 Watershed Report Cards

​​The NVCA began producing Subwatershed Report Cards in 2007. ​In 2013, these were re-launched with the title "Health Check" to ensure a distinction between these and the provincial Watershed Report Cards. ​

Provincial Watershed Report Cards

Along with many of the 36 conservation authorities in Ontario, the NVCA produces a Watershed Report Card. This was designed by conservation authority staff under the guidance of Conservation Ontario in order to allow a province-wide snapshot of water quality, forest conditions, groundwater quality and wetlands based on a common set of measurements and criteria.
