A targeted approach to dredging White Rock Lake

The long wait for dredging White Rock Lake has been a source of frustration for Dallas residents. It should have been done years ago, but the city has been putting this task on the back burner.

Historically, removing sediment and other materials from the lake has been done about every two decades. But the last time was in 1998.

A full dredging of the lake, however, is a cost-prohibitive process in today’s dollars, estimated at between $53 million and $80 million, according to a 2020 feasibility study.

The sediment buildup is harmful to the overall health of the lake. Shallow waters make it unsafe for recreation, boating and sailing. White Rock Lake literally breathes life into Dallas; it is a vital community resource for our city. We need to get this dredging done.

The good news is that the city is rethinking its approach. Instead of taking on the entire lake all at once, it is moving forward with a targeted dredging strategy recommended by the project’s engineering consultant. This program would focus on specific areas with high sedimentation, and it will be scaled to the available budget. This is a pragmatic approach that could work.

Dallas has a pattern of delaying maintenance and operations, with its own City Hall as Exhibit A. It has been nearly three decades since sediment buildup was removed from the lake. The idea of making this a permanent program with phased dredging every five to seven years is something we can get behind. It would create a badly needed maintenance process.

The City Council recently approved a supplemental agreement expanding its engineering services contract with Freese and Nichols, the firm that has been providing design and engineering work on White Rock Lake since 2022. It will be tasked with identifying and prioritizing dredge areas based on available funding. But actual dredging would not begin before December 2028, when this design phase is completed.

The city has $2 million in federal funding for the design phase and voters approved up to $20 million as part of the 2024 bond package. Still, funding is insufficient for a full dredging of the lake.

Council member Paula Blackmon, who represents District 9, where White Rock Lake is located, told us she tried looking into federal and state funding to dredge the lake, but those efforts were unsuccessful. The reason is that White Rock Lake is a recreational lake. It is difficult to compete for funding with lakes that provide drinking water to communities struggling with drought, she told us.

Blackmon said this targeted dredging approach was ultimately forced by economics, but it makes sense in the long term. It is a sustainable method guided by data that will lead to improved maintenance.
