This concrete gravity dam, completed in 1903, stands at a height of 25 feet and stretches 467 feet in length, with a storage capacity of 120 acre-feet. Operated by the Federal Energy Regulatory Commission, this dam plays a crucial role in generating clean energy for the region.
With a high hazard potential and a moderate risk assessment rating, Cross Power is closely monitored and regulated by the NHDES Dam Bureau and FERC. Despite its age, the dam remains in good condition and is regularly inspected to ensure its safety and functionality. The dam's uncontrolled spillway, with a width of 325 feet, can handle a maximum discharge of 24,000 cubic feet per second, making it a key structure for managing water flow in the area.
As a key part of New Hampshire's hydroelectric infrastructure, Cross Power serves as a testament to the enduring importance of sustainable energy generation and water resource management. Its role in providing renewable power and regulating water flow highlights the intersection of environmental conservation and energy production, making it a vital asset for both the local community and the broader region.
