RUSSELLS POINT — A new labyrinth configuration is set to repair the Indian Lake spillway while maintaining current water levels this summer.
The labyrinth design will remain at 700 feet, but will contain a center structure of 160 feet that allows for the same flow downstream that the current spillway allows currently using the entire 700 feet, according to state officials who spoke at a meeting Wednesday evening at the Indian Lake Community Church Lighthouse.
The $8 million project is designed to add additional capacity for storm events, while having a smaller footprint for flow and balancing downstream and upstream conditions said Rob Kirkbride, a project design engineer for the Ohio Department of Natural Resources.
“One of the biggest concerns with people are the water levels,” said Jim Ellington, who lives near Indian Lake. “People just want to know how construction is going to directly impact them.”
Water levels for the lake are to stay the same throughout the construction. Lowering of water levels by several inches may take place in the case of a storm to ensure dam safety, but the size of the lake allows for a large storm capacity.
Embankment modification is also set to take place alongside the spillway construction. The embankment contains seepage because of pressure from the lake, which is common among earthen dams.
“We hope to give the area a bit more stability to keep the water in place so it doesn’t cause seepage,” Kirkbride said.
Construction is projected to begin after Labor Day and be completed in the summer or fall of 2017.
