Sydenham Phosphorus Reduction Initiative

Home StewardshipHealthy Watersheds ProgramSydenham Phosphorus Reduction Initiative

New funding is available to support practices that will help reduce phosphorus losses within the Sydenham River Watershed.

St. Clair Conservation recently secured four years of funding through the Canada Water Agency to support the Sydenham Phosphorus Reduction Initiative (SPRI). The goals of SPRI are:

1. To decrease the overall non-point source phosphorus loads in the Sydenham River Watershed, as the River is the 3rd largest Canadian contributor of phosphorus to Lake Erie and,

2. To increase the adoption and sustainability of agricultural and rural Best Management Practices (BMPs) in high phosphorus-yielding areas.

With over 80% of the St. Clair Region watershed comprised of agricultural land, BMPs such as windbreaks, cover crops, and wetland restoration are critical in minimizing phosphorus losses to waterways. These practices can also help to reduce soil erosion, protect water quality, increase crop yields, and potentially decrease the need for fertilizer. Additionally, implementing BMPs improves habitat for aquatic wildlife, specifically our local Species at Risk.

Review the guidelines below and contact us to discuss solutions that will work in your farm operation.

Funding priority goes to farmers and rural landowners in the SPRI subwatersheds: Sydenham Headwaters, Bear Creek, and Brown Creek.

If you live outside these priority subwatersheds, you can still apply.

The Sydenham Phosphorus Reduction Initiative (SPRI) is aimed at reducing phosphorus loading in the Sydenham River and, ultimately, Lake Erie. The Sydenham River Watershed is the third-largest Canadian contributor to phosphorus loads in Lake Erie, with pollution from widespread sources like agricultural and rural runoff accounting for approximately 89% of the total phosphorus released annually (Dagnew et al., 2019).

If you are interested in learning more about phosphorus loads in Lake Erie and the Sydenham River, please visit the below references used to build this program:

What Are Best Management Practices (BMPs)?

BMPs are practical, cost-effective methods that help care for the environment while boosting your farm’s productivity. These practices reduce soil erosion, improve water quality, conserve wildlife habitats, and promote sustainable land use.

The image to the right shows four different BMPs – tiered wetlands, grassed waterways, tree planting, and cover crops in the distance.
