White Rock Lake Reclamation, 1999 OCEA
Share |

White Rock Lake, located approximately 5 miles from downtown Dallas,became the city’s first public surface water supply when it was built in 1911. The 1,100-acre lake is the centerpiece of the 2,100-acre White Rock Lake Park - a local favorite for jogging, fishing, sailing, and picnicking - amongst other activities. However, prior to the Reclamation project, this landmark resource was being threatened by years of sediment build-up. Dallas citizens, city officials, and engineering professionals supported a dredging and restoration project which was completed in 1999.


Project engineers showed resourcefulness in managing the various problems that arose, including disposal of 3,000,000 cubic yards of material (enough to cover a 300 acre area, six-foot deep) and proximity to park facilities and urban surroundings. Detailed hydraulic analysis and effective project management made possible the piping of sediment slurry a record distance of 17 miles, which was a feat most dredging contractors had previously thought impossible. The project, having become the longest pipeline dredging project ever attempted in the U.S., was completed on time and within budget without any negative impact to the environment or adjacent neighborhoods.
