:''This article concerns the dam near
Columbus, Ohio. For the one in the
Sierra Nevada mountains, see
O'Shaughnessy Dam.''
Background
The 'O'Shaughnessy Dam' is located on the
Scioto River near
Dublin, Ohio,
USA. The dam forms O'Shaughnessy Reservoir, which is a major source of drinking water for the city of
Columbus. It was completed
1925 following recommendations of then superintendent Jerry O'Shaughnessy (for whom the dam was named).
[1] Located 10 miles 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 gallons (24 million cubic meters) over a surface area of 845 acres (342 hectares).
[2] The
Columbus Zoo and Aquarium is located on the east bank of the reservoir, near the dam.

Hydroelectricity
The city of Columbus installed a
hydroelectric operation on the west side of the dam, which was completed in
1987.
[3] 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 meters)
[4], the two turbines together produce 5 megawatts.
