City to repair cracked Walton Lake spillway

By Andy Hallman, Ledger news editor | Apr 26, 2017

The spillway at Walton Lake will get a makeover this summer.

Fairfield water department superintendent Steve Redinger said the spillway is in disrepair. The Iowa Department of Natural Resources and the city’s insurance provider have told the city it needs to fix it before it gets any worse.

“If we don’t fix it, it will erode the dam itself under the spillway,” Redinger said. “The dam could fail if we let it get bad enough.”

The purpose of the spillway is to keep the water level in the lake at a constant level. During a rain, water fills up in the lake and is released through the spillway into a creek.

Redinger said in an interview Tuesday that the dam itself is in good shape, but the floor of the spillway is cracked and its retaining walls are in bad shape.

“We’ll just replace where it’s getting bad and pour a whole new floor,” he said.

The engineer estimated the project would cost $189,000 if done in-house, meaning done by city employees. If the city hired a contractor to do it, it would cost more than double that, Redinger said.

Repairing the spillway will be a joint effort of multiple city departments such as the water, wastewater and street departments.

Redinger remarked that it would take all the machinery and manpower the city has. The city hopes to finish the project by July 1.
