Built in 1926, this masonry dam stands at a height of 15 feet and has a storage capacity of 620 acre-feet. With a maximum discharge rate of 37,500 cubic feet per second, Granby plays a crucial role in both hydroelectric power generation and navigation along the river.
Managed by the Federal Energy Regulatory Commission, Granby has a spillway width of 500 feet and covers a surface area of 33 acres. Despite its significant hazard potential, the dam's condition assessment is currently marked as "Not Available," highlighting the need for regular inspections and maintenance. In case of emergencies, an Emergency Action Plan was last revised in December 2019 to ensure the safety of surrounding communities in the event of a dam failure.
With its rich history and vital role in water resource management, Granby serves as a key infrastructure for sustainable energy production and waterway navigation in the region. As climate change continues to impact water resources, the maintenance and upkeep of dams like Granby are essential to ensure their long-term safety and functionality in the face of evolving environmental challenges.
