Built in 1900 for hydroelectric purposes, this earth dam spans 652 feet in length and reaches a height of 10 feet, providing a storage capacity of 8,100 acre-feet. Despite its low hazard potential, the dam's risk assessment is marked as high due to its age and the lack of available condition assessment data.
Managed by the Federal Energy Regulatory Commission, Stone Dam - Dike 1 serves multiple purposes including flood risk reduction, water supply, and recreation. With a surface area of 1,344 acres and a drainage area of 1,890 acres, the dam plays a significant role in regulating the flow of the river and supporting fish and wildlife habitats. However, the lack of recent inspections and condition assessments raises concerns about its long-term sustainability and safety.
As a key component of the region's water resource infrastructure, Stone Dam - Dike 1 requires ongoing monitoring and maintenance to ensure its continued functionality and safety. With a primary focus on hydroelectric power generation, the dam also contributes to navigation and recreation activities in the area. By prioritizing risk management measures and investing in regular inspections, stakeholders can safeguard this vital structure and preserve the ecological balance of the West Branch Penobscot River for future generations.
