Location and Description
Lake White Dam, built in 1935, is part of Lake White State Park located near Waverly in Pike County. It measures 4,200 feet long and carries a portion of Ohio Route 104, which includes a short bridge span passing across the top of the spillway structure. Most of the lake bed and land surrounding the lake is privately-owned.
The dam has a principal spillway consisting of a concrete weir with tainter gates. The lake surface area at the spillway during full pool is approximately 400 acres. Total drainage area to the lake is 35 square miles. Significant precipitation events within the drainage area can cause rapid and significant increases in the lake level. The spillway discharges water beneath the Ohio Route 104 bridge span into Crooked Creek, which flows into the nearby Scioto River just south of Waverly. As a Class I high-hazard potential structure, a sudden failure of Lake White Dam likely would result in the structural collapse of at least one residence or other structure and probable loss of human life. (Hazard ratings refer to the consequences of dam failure, not the dam’s condition.)

Lake White Dam currently has deficiencies that must be addressed to bring the structure into compliance with dam safety standards and to ensure public safety. These deficiencies are documented in recent engineering investigations and Ohio Dam Safety Program inspections. Some examples of these deficiencies and other complicating factors include:
- Seepage and instability concerns at the concrete spillway and along the dam.
- Insufficient storage and discharge capacity.
- Inoperable lake drain.
In late summer, 2014 significant seepage was detected below the Lake White Dam adjacent to a spillway wall prompting an emergency response and interim risk reduction measures by ODNR. Included in these measures was a lowering of the lake level to approximately 11 feet below winter pool – a level that since has been maintained until permanent repairs can be made. The lowered lake level is a standard risk reduction measure that reduces the likelihood of seepage under the spillway and dam. Plans to repair the dam have been in process for several years. The seepage beneath the spillway wall is a new problem that developed will be remediated as part of the overall risk reduction project.
Long Term Plan
Routine inspections and maintenance of the dam will continue. An emergency action plan will be revised and shared with local emergency management officials one it is completed.
Following significant weather-related impacts that occurred during the summer, the Lake White project has been extended through the first half of 2017. Along with several flooding events in 2016, a shutdown at the materials suppliers' plants precluded the delivery of materials needed to complete the placement of the roller compacted concrete (RCC) on the dam.
As of December, 2016 however, the contractors have completed the lake drain, painted the spillway gates, placed the RCC in the basin and dam face, relocated Crooked Creek, and armored the dam face with rock. In addition, the bridge component of the roadway work is nearly 80 percent complete.
This winter, crews will be completing the RCC placement on the dam crest, realigning C.R. 105, placing concrete pavement on S.R. 104 for the length of the dam, reconstructing S.R. 552 and S.R. 551 intersections with S.R. 104 and remediating a slip along C.R. 105. Although most construction will be on a winter hiatus in the upcoming weeks, the contractors will continue working as weather permits during the winter months.
