The O'Shaughnessy Dam is located on the Scioto River near Dublin, Ohio, United States. The dam forms O'Shaughnessy Reservoir, which is a major source of drinking water for the city of Columbus. It was completed in 1925 following recommendations of then superintendent Jerry O'Shaughnessy (for whom the dam was named).[2] At the time, the reservoir was described as "the finest inland waterway in the United States." Located 10 miles (16 km) upstream of the smaller Griggs Dam, it provides a large area for various forms of recreation in addition to its water supply duties. The reservoir holds 6.3 billion US gallons (24,000,000 m3) over a surface area of 845 acres (3.42 km2).[3] The Columbus Zoo and Aquarium is located on the east bank of the reservoir, near the dam.

In 1990, the dam was listed on the National Register of Historic Places.[1]

Hydroelectricity

The city of Columbus installed a hydroelectric operation on the west side of the dam, which was completed in 1987.[4] The turbines can only be operated when there is sufficient flow, which means the dam cannot continuously produce electricity. With a head of 18 feet (5.5 m)[5], the two turbines together produce 5 megawatts.[4][6]
