With a dam height of 27 feet and a length of 450 feet, it serves primarily for recreational purposes, offering a tranquil setting for visitors to enjoy the surrounding natural beauty. The dam has a low hazard potential and is in satisfactory condition, with regular inspections conducted by the Maryland Dam Safety agency to ensure its safety and integrity.
The original design of Daniels Dam was carried out by Ambursen Engineering, with Stone&Webster later adding a fish ladder to assist with fish migration. Over the years, the dam has undergone modifications in 1993 to reinforce its foundation and structure. With a storage capacity of 1500 acre-feet and a drainage area of 265.8 square miles, the dam plays a crucial role in managing water resources in the region and supporting the ecosystem of the Patapsco River.
Despite its historical significance and recreational value, Daniels Dam poses a moderate risk level (3) according to risk assessments. The dam's spillway, with a width of 278 feet, is uncontrolled, allowing for the release of excess water during periods of high flow. With Elijah E. Cummings representing the area in Congress, efforts are made to ensure the proper management and maintenance of the dam for the safety and enjoyment of all who visit this picturesque location.
