The installation of a Tainter Gate as part of the Lake D’arbonne water control t’aint as easy as you’d think. But after numerous delays, mostly due to weather, project manager Ron Riley told the D’Arbonne Lake Commission last week that “the end is in sight.”
Testing on the big gate, located on the western side of the current spillway, is scheduled for most of this week. If all works as expected, the rest of the work to make the gate functional should be complete by mid October, Riley said.
Once the gate has checked out, there is still a lot of detail work. Electricity will then have to be permanently connected to the structure. Testing is being done with the aid of a generator. There will have to be rip rap added below the gate, removal of a large cofferdam and other support work completed.
The gate has been under construction for over two years and is expected to offer the Department of Transportation, which manages the spillway structures, a way to drop the lake a bit quicker than normal in instances of threatening floods.
