Hoover Dam CIP

General Description
The City of Columbus Department of Public Utilities is making improvements to the dam at Hoover Reservoir under the Hoover Dam Improvements Part 1 project. The dam, which is one of several in the city’s water supply system, is located on the Big Walnut Creek at the south end of the reservoir. It supplies water to the Hap Cremean Water Plant, which in turn, provides drinking water to approximately 600,000 customers.

This project will make improvements to the dam to maintain a reliable water supply and extend the life of this critical asset. Work will include replacing dam equipment (gates, valves, piping etc.) and other systems (electrical, dehumidify etc.). Many of these elements are original to the dam, built in the 1950s, and are in need of replacement or repair due to age.  

Construction Schedule
Work began August 2020 and is expected to be complete in summer 2022.

What to Expect
To address public safety, contractor safety, and maintain security, the dam and some parking areas must be closed to the public during construction. During this period, all or portions of roads, walkways and parking areas will be closed. Signage will be posted before work begins. View the Project Map and more details are below.  

Areas to be closed during construction will include:

  • the road and western portion of pedestrian bridge on the crest of the dam
  • the southern half of the parking lot on the west side of the dam (off Sunbury Road)
  • the parking lot on the southwest side of the dam (adjacent to the soccer fields)
  • the road from the west parking lots to the parking lot on the southwest side of the dam
  • the stairs on the west end of the dam  

Other areas to be closed intermittently, with anticipated closure periods:

  • parking lot nearest the marina (intermittently through the construction schedule)
  • east access road from Central College Road (intermittently through the construction schedule)
  • the dam spillway bridge (closed through the construction schedule)

Construction Cost
This $15 million project is being financed through low interest loans paid back through Division of Water ratepayer revenue.
