Crews will begin a year-long repair project on the Griffy Lake Dam next week as the city of Bloomington plans to drain the lake next month to repair the dam.
A flood during the summer of 2008 damaged the Griffy Lake Dam. Steve Cotter is Bloomington Parks and Recreation’s natural resources manager. He says the city’s utilities department received a $1.5 million dollar state grant to conduct repairs.
“They’ll be doing some work to repair broken concrete, cracked concrete in the spill way and then most importantly to people who fish out here they’re going to replace the sluice gate which regulates how much water is in the lake,” he says.
The dam’s sluice gate has been leaking for the past three years. The leak and low rainfall amounts have contributed to Griffy Lake’s low water levels.
The first stage of the project will be to replace the culvert that runs under Dunn Street which channels water into Griffy Creek. Once a new culvert is installed they will begin draining the lake, which should take about a month.
Cotter says once the lake is drained that they will hopefully be able to remove built up sediment which will allow boaters to more easily reach the west end of the lake once it is refilled.
“That will facilitate boating,” he says. “It will allow people to get to the boat ramp next to the boathouse, under the bridge that goes under Hedley Road over here to the deeper part of the lake.”
The dog park behind the dam will be closed as it will be used as a staging area for construction equipment.
Cotter says Dunn Street will also be closed north of the dam as early as next week.
