Lawrence River in Massena, New York. Built in 1958 by Chas. T. Main, this Earth-type dam stands at a height of 25 feet and stretches 4300 feet in length. With a maximum storage capacity of 803,000 acre-feet and covering a surface area of 37,500 acres, the dam plays a crucial role in hydroelectric power generation and navigation in the region.
Managed by the Federal Energy Regulatory Commission, Long Sault North has a high hazard potential and is subject to regular state inspections. Despite its age, the dam's condition assessment is currently unavailable, signaling a need for further evaluation to ensure its safety and structural integrity. With a drainage area of 300,000 acres and a normal storage capacity of 750,000 acre-feet, this dam remains a significant water resource management structure in the St. Lawrence River watershed.
As a key component of New York's water infrastructure, Long Sault North serves as a vital source of renewable energy and contributes to the region's economic development. With its high risk potential and complex regulatory oversight, the dam underscores the importance of effective risk management and emergency preparedness in safeguarding water resources and addressing the impacts of climate change on water infrastructure systems.
