This earth dam serves primarily for irrigation purposes, with additional benefits for recreation. The dam stands at a height of 43 feet, with a hydraulic height of 37 feet and a structural height of 50 feet, spanning a length of 700 feet. It has a storage capacity of 800 acre-feet and covers a surface area of 29.1 acres, drawing water from the East Branch and Collington Branch rivers.
Despite its fair condition assessment and low hazard potential, Beechtree Dam is subject to state regulation and inspection by the Maryland Dam Safety agency. Its spillway, a crucial component for controlling water flow, is uncontrolled with a width of 12 feet. The dam has a maximum discharge capacity of 2500 cubic feet per second and is equipped with slide (sluice gate) outlet gates. While the risk assessment categorizes Beechtree Dam as moderate, measures for risk management and emergency action planning are not explicitly outlined in the data.
In the event of any modifications or updates to Beechtree Dam, the last inspection was conducted in November 2018 with a scheduled inspection frequency of 5 years. With Congressman Anthony G. Brown (D) representing the area, stakeholders and water resource enthusiasts closely monitor the dam's condition and regulatory compliance. As a vital infrastructure for irrigation and recreation, Beechtree Dam plays a significant role in water resource management within Prince George's County, Maryland.
