2024/2025 In-River Activities
2024/2025 WINTER: Barges will be stored over the winter just upstream of the Route 131 bridge on the north side of the river – see additional details. Please maintain a safe distance and use extreme caution when traveling through this area.
2025 ACTIVITIES: The long-term monitoring program will continue in 2025 and includes monitoring of the caps and monitoring PCB levels in water and fish. Habitat features and plantings placed along the shoreline and on land in previous years will again be monitored in 2025.
A high-flow event caused by the remnants of Hurricane Debby occurred in August 2024 resulting in limited cap areas downstream of the Route 131 bridge requiring repair. Details are provided in the October Community Update. These repairs were initiated in late 2024 and will continue into 2025.

The five-year review report is available on EPAs project webpage.
