Swansea Lake Faces Environmental Challenges Following Recent Flooding

During a recent government meeting, officials discussed the alarming state of Swansea Lake following a significant flood last summer. The flood, which occurred on July 10, deposited large amounts of sediment, including silt and topsoil, into the lake, raising concerns about water quality and phosphorus levels.

The meeting highlighted findings from a study conducted by FE Environmental Associates, which indicated that phosphorus levels in the lake could be on the rise. Phosphorus has long been a concern for Swansea Lake, with reports dating back to the 1990s emphasizing its impact on the ecosystem. The current situation has prompted officials to seek more detailed water quality testing to understand the flood's effects and to develop remediation strategies.

The conservation commission has already allocated $25,100 towards the testing, which is estimated to cost between $73,000 and $76,100 for six testing days from June to October. However, with June already passed, the number of testing days may be reduced, potentially lowering costs. Officials are now appealing for additional funding to ensure comprehensive testing can be conducted.

The discussions underscored the importance of addressing internal phosphorus loading, which accounts for approximately 17% of phosphorus in the lake, primarily from sediment at the lake's bottom. The meeting also touched on potential remediation efforts, including stricter regulations on septic systems and promoting low-phosphorus fertilization practices among homeowners.

As the community grapples with these environmental challenges, officials emphasized the need for immediate action to prevent further degradation of Swansea Lake, which has been a cherished local resource for decades. The urgency of the situation has reignited discussions that have been ongoing since the 1990s, highlighting the critical need for proactive measures to protect the lake's health.
