Mayfield Dam, also known as Mayfield Lake, is a state-owned structure located in Mayfield, New York. Built in 1930, this earth dam stands at a height of 36 feet and spans 370 feet in length, with a storage capacity of 1,836 acre-feet. The primary purpose of the dam is flood risk reduction, serving as a crucial tool in protecting the local community from potential water-related disasters.

Managed by the New York State Department of Environmental Conservation (NYS DEC), Mayfield Dam is regulated, permitted, inspected, and enforced by the state agency to ensure its safety and functionality. The dam's controlled spillway, with a width of 81 feet, helps manage water discharge during periods of high flow. With a hazard potential rated as low and a risk assessment indicating a very high risk level, Mayfield Dam plays a vital role in water resource management and climate resilience efforts in the region.

In addition to flood risk reduction, Mayfield Dam offers recreational opportunities and contributes to the overall water management strategy in the area. With its strategic location on Mayfield Creek, this important infrastructure project continues to be a key asset in protecting the community and surrounding areas from the impacts of extreme weather events and ensuring sustainable water resource management for the future.
