Falmouth's Water Quality Management Committee has taken a significant step towards enhancing the health of Bournes Pond and its surrounding areas. During their meeting on November 6, 2024, committee members discussed a comprehensive project aimed at widening the inlet, rebuilding jetties, constructing groins, and implementing a beach nourishment initiative on the east side. These efforts are designed to improve water quality and maintain the integrity of local roads, particularly in light of ongoing concerns about sea level rise.

The project will address critical infrastructure issues, as the road leading to the bridge has settled significantly over time. While there was discussion about the potential for elevating the road to combat rising sea levels, the town has opted to maintain the current elevation to avoid disrupting local boating activities and the natural state of the pond.

The committee highlighted the importance of modeling and engineering design in this project, referencing past studies and updated bathymetric data to ensure effective planning. The goal is to widen the inlet to approximately 100 feet, which is expected to enhance tidal currents and prevent the need for frequent dredging. This strategic widening aims to facilitate the natural movement of sand and improve water quality by increasing the flushing capacity of the estuary.

Preliminary modeling results indicate that the proposed changes could lead to an 8% improvement in total nitrogen concentrations in the water, with even greater benefits—up to 15%—in the southern areas of the estuary. This translates to a substantial reduction in nitrogen load to the watershed adjacent to Bournes Pond, equating to a 57% decrease in nitrogen pollution.

The committee's discussions underscore the importance of proactive measures to safeguard Falmouth's water quality and infrastructure. As the project moves forward, it promises to deliver tangible benefits to the community, enhancing both environmental health and local recreational opportunities.
