The Ohio Department of Natural Resources (ODNR) has $6.4 million in ongoing projects in Shawnee State Park. The projects are a part of the Dam Rick Reduction Program. The two projects in Shawnee State Park are at Pond Lick Lake and Roosevelt Lake Dam.

In describing the Dam Risk Reduction Program, engineering.ohiodnr.gov states, “ODNR is working to implement several Class 1 high-hazard dam rick-reduction projects across the state, including some large-scale dam rehabilitation projects to protect the public from catastrophic dam failures and safeguard local economies tied to ODNR-owned reservoirs. Current assessments show that no ODNR-owned dam is in immediate danger of failure requiring emergency repairs.

Ohio has 364 high hazard dams that are publicly as well as privately-owned. The publicly owned Class 1 high-hazard dams more in need of repair, or other rick reduction measures, as located within Buckeye Lake State Park, Hueston Woods State Park, Strounds Run State Park, Pike Lake State Park, Mount Gilead State Park, Shawnee State Park and Protage Lakes State Park.”

ODNR describes the Roosevelt Lake Dam as, “an earthen embankment that is 535 feet long and 26 feet high.”

According to ODNR, “this rehabilitation of the (Roosevelt Lake) dam will include roller compacted concrete (RCC) over-topping protection and renovations to the principal spillway. Spillway renovations include stabilization via post tensioned rock anchors which will require drilling through the dam and into the rock below. The top of the concrete weir will be removed and replaced as part of the anchoring. The training walls will be raised in order to flatten the slope of the embankment and will be refaced with new concrete that will be architecturally stamped and stained to mimic the existing stone walls downstream of the dam. The existing stonewalls downstream of the dam will also be replaced with architecturally treated concrete walls.”

Other improvements associated with this project include, “renovations of the existing lake drain system which will include a new section of 24-inch ductile iron pipe, a control tower which includes two 24-inch sluice gates and an access bridge. All regulatory permitting including USACE has been procured prior to construction.”

Sunesis Construction Co., of West Chester, Ohio, was the low-bidder on the project. Michael Baker Jr. Inc. will be providing construction management oversight to ensure that the construction is conducted in accordance with the drawings and specifications. The total estimated cost of construction of these improvements is $3,711,352. Construction is expected to be completed by Oct. 15, 2014.

The project at Pond Lick Lake calls for roller compacted concrete (RCC) over-topping protection and replacing the principal spillway system in-kind. Replacement of the existing lake drain system with a new 24-inch ductile iron pipe and control tower which includes a 24-inch resilient wedge gate. The plans also include abandonment of the exiting lake drain and a newly designed stilling basin for the principal spillway. All regulatory permitting including USACE has been procured prior to construction.
