The Portage Lakes Dam Project

Pete Nix, P.E., Senior Program Manager, Tetra Tech

East Reservoir is part of Portage Lakes State Park located near Akron in Summit County. It was built around 1840 as a water supply reservoir for the Ohio and Erie Canal. The 1,400-foot long dam consists of three distinct sections with a maximum crest width of 40-50 feet and impounds approximately 900 surface acres of water. It receives water flow from West Reservoir through the 1,500 foot long “Iron Channel”. As a Class I high-hazard potential structure, a sudden failure of East Reservoir Dam likely would result in the structural collapse of at least one residence or commercial/industrial business and loss of human life. (Hazard ratings refer to the consequences of dam failure; not the dam’s condition.)

ODNR contracted with Tetra Tech to provide investigations, preliminary design and final design alternatives. Their investigations of the dam structure in 2013 and subsequent study revealed various deficiencies that require remediation. Final design was completed in early 2017 and include risk reduction measures intended to bring the dam and its appurtenances into compliance with dam safety standards and industry best management practices. Construction began in late 2017 with completion set for 2019.

North Reservoir is part of Portage Lakes State Park located near Akron in Summit County. The present dam was completed in 1909 as the New Reservoir Dam and comprised of two earthen embankments of nearly equal length that are separated by several hundred feet of natural ground. The combined length of the dam is 650 feet, which impounds approximately 166 surface acres of water to an average depth of 11 feet. The spillway and outlet pipe discharges lake water into a stilling basin and outflow channel connecting to Long Lake. As a Class I high-hazard potential structure, a sudden failure of North Reservoir Dam likely would result in the structural collapse of at least one residence or commercial/industrial business and loss of human life.

North Reservoir Dam currently has deficiencies that must be addressed to bring the dam into compliance with dam safety standards. The deficiencies include insufficient storage/discharge capacity and it cannot pass the required design storm safely. Excessive seepage through and under the embankment, along with severe concrete deterioration on the north spillway and lake drain structure also are present.

ODNR is contracted with Tetra Tech to provide investigations, and preliminary and final design alternatives. Their investigations of the dam structure (2013) revealed various deficiencies that require remediation. Final design will include risk reduction measures intended to bring the dam and its appurtenances into compliance with dam safety standards and industry best management practices.
