The dam stretches 495 feet in length and has a maximum storage capacity of 5843 acre-feet, making it a vital water resource for the region.

With its primary purpose being hydroelectric power generation, Lower Bucks Lake also serves recreational and water supply needs. The reservoir covers a surface area of 136 acres and has a drainage area of 31.2 square miles. The dam's spillway, with a width of 200 feet, is uncontrolled, and its high hazard potential necessitates regular inspections by the Federal Energy Regulatory Commission to ensure safety and compliance with regulations.
