Project Overview

About the Middle Dam Project

As the owner of Middle Dam, Brookfield White Pine Hydro, LLC is required to meet certain dam safety criteria mandated by the Federal Energy Regulatory Commission’s (FERC) license issued in 2002 to operate and maintain the facility. Middle Dam is a circa 1850s dam that has undergone numerous repair and upgrade efforts during its lifetime. The facility must undergo future repairs to meet FERC dam safety requirements. After evaluating both replacement and in-kind repair options, Brookfield White Pine Hydro, LLC, has determined to pursue a repair, which will minimize stakeholder and environmental impacts. Continued detailed on-site inspections, consultation, and coordination with FERC engineers, and an Independent Engineer, along with ongoing discussions with stakeholders have resulted in making this determination. Specifically, the repair project will meet the dam safety criteria of accommodating Inflow Design Flood (IDF). We do not anticipate significant impacts to recreational and fishing access, or aquatic habitat with the repair option. The piers, aquatic habitat, and access to the pool are expected to remain as is following the repair efforts.

 

Current Status

We are pleased to share that construction activities associated with the Middle Dam maintenance project were successfully completed at the end of 2025. This work represents a significant investment in the long‑term safety and reliability of the facility.

Crews are expected to return to the site in spring 2026 to complete minor cosmetic items, such as painting and finish work. These activities will be short‑term in nature and are not anticipated to result in additional impacts.

We would like to thank local residents, recreational users, and other interested stakeholders for their patience and understanding throughout the construction process. Your cooperation and engagement were greatly appreciated as we worked to complete this important maintenance project.
