Dallas Water Utilities (DWU) is progressing on the Bachman Lake Dredging and Dam and Spillway Rehabilitation Projects.
DWU said in their latest project update that they have awarded a construction services contract for dredging at Bachman Lake and is continuing engineering efforts for dam and spillway improvements.
The construction contract for the first phase of improvements, lake dredging, was approved by the Dallas City Council on October 29, 2021.
Renda Environmental, Inc. will begin equipment mobilization in January 2022 , with dredging activities beginning in February 2022.
The contractor will use a dredging barge to pump silt to an off-site location, where the slurry will be “dewatered.” The dewatered sediment will be disposed of, while the water will be clarified and pumped back into Bachman Lake.
Dredging will result in the removal of 370,000 cubic yards of accumulated sediment from the lake and restore water depth to a minimum of eight feet. This depth prevents invasive aquatic vegetation from taking hold and removes debris and trash from the lake bottom, improving water quality and restoring the lake to recreation levels.
Dam and spillway improvements are in the final design phase and planned for construction following the conclusion of the dredging work.
