Lee is a private dam located in Graham, Arizona, specifically in the city of Eden. Built in 1981, this Earth dam serves the primary purpose of flood risk reduction along the Gila River - TR. With a height of 61 feet and a structural height of 71 feet, Lee has a storage capacity of 211 acre-feet and covers a surface area of 8.6 acres. Despite its high hazard potential, the dam's condition assessment as of December 2017 was deemed satisfactory.

Managed by the Arizona Department of Water Resources, Lee undergoes regular state inspection, permitting, and enforcement to ensure its integrity and safety. The dam, situated within a drainage area of 0.3 square miles, plays a crucial role in mitigating flood risks in the region. Although it lacks a spillway, Lee's satisfactory condition and high-risk assessment level indicate the importance of ongoing monitoring and maintenance to protect downstream communities and ecosystems from potential flooding incidents. For water resource and climate enthusiasts, Lee represents a vital infrastructure component in Arizona's flood risk management strategy.
