To minimize the impact of the work on the lake bed, crews installed silt curtains to keep debris from spreading and water quality was tested daily.
To make the repair, divers first removed a 3-to 4-inch-thick coating of concrete from the pipeline, and then bolted on a specialized clamp to reinforce the 0.345-inch-thick steel walls of the pipeline.
A team of experienced divers equipped with video cameras and live audio feeds worked in murky underwater conditions to repair the pipe.
