Project Description As part of the Ohio Department of Natural Resources (ODNR) ongoing Statewide Dam Rehabilitation Initiative, ODNR is requesting professional engineering services to provide final design and construction stage services for statewide dam improvement projects at Cowan Lake State Park, Lake Logan State Park, Shawnee State Forest, and Perry State Forest. Through this selection process, ODNR intends to select three (3) firms to receive contracts. It is not anticipated to award more than one (1) contract per firm. Firms will be given preference to select their contracts listed below based upon scoring results. It is the intent of the Contracting Authority to offer the highest scoring firm first choice, second highest scoring firm will be offered the second choice, remaining contracts will be awarded by the same selection method. The Contracting Authority reserves the right to consider other factors in the award of the contract, including site location, workload, firm experience, and capabilities. As scope and associated costs are solidified, projects of similar types, scope, and budget may be added or removed as ODNR initiatives and funding allow. Accordingly, contracts with the selected firms may be extended and amended to meet the goals of the Statewide Dam Rehabilitation Initiative. Cowan Lake Dam Rehabilitation Cowan Lake is a 692-acre recreational lake on Cowan Creek located within Cowan Lake State Park in Vernon Township, Clinton County, Ohio. Cowan Lake Dam, constructed in 1947, carries State Route 730 across the crest of the dam and consists of a concrete spillway, concrete lake drain, and an earthen/rockfill dam embankment. The dam currently impounds Cowan Creek and is located approximately three miles upstream of the confluence of Cowan Creek and Todd Fork. The dam is owned and operated by the ODNR Division of Parks and Watercraft. Cowan Lake currently serves as a public recreation facility used for fishing, swimming, kayaking, and boating. Cowan Lake Dam has been classified as a Class I dam due to the height of dam, storage capacity, and the population at risk within the flood inundation zone. An assessment completed in 2020 evaluated the current condition of Cowan Lake Dam in order to identify deficiencies and to develop conceptual rehabilitation alternatives to bring the dam into compliance with current dam safety regulations.
