Leon Hurse Dam at Lake Ralph Hall

  • Leon Hurse Dam at Lake Ralph Hall

After nearly two decades, Lake Ralph Hall, named after former Congressperson Ralph M. Hall, is now under construction. With the local population in northern Texas expected to grow five-fold in the next 50 years, the Lake Ralph Hall and Leon Hurse Dam project will deliver 54 million gallons of water daily (with reuse) to 29 communities when complete.

New Dam and Reservoir

The Lake Ralph Hall program includes the Leon Hurse Dam – an earth fill embankment, a roller compacted concrete spillway, and reinforced concrete gated outlet and intake structure; roadway relocations – State Highway (SH) 34 and Farm to Market (FM) 1550 relocations; limited stream restoration; a conveyance system – raw water pump station, raw water pipeline and balancing reservoir; and the lake administration and maintenance facilities.

Quality Assurance and Materials Testing

Kleinfelder is providing quality management and assurance, document control, and materials testing, including:

  • Document management and control
  • Inspection of reinforcing steel prior to concrete placement for size, spacing, type, grade, identification, placement, and configuration
  • Materials testing and inspection of soil
  • Observation and sampling of concrete during placement including casting cylinders for compression testing, monitoring slump, temperature, and mixing time, as required by the plans/specification
  • Observation of installation and tightening of high strength bolts including sampling and tension/torque testing
  • Observation of welding operations on site during structural steel erection and connection on a continuous and periodic basis, including review of welder certifications, material identification, joint fit-up, and pre/post-weld heat treatment
  • Quality management, planning, and assurance
  • Visual inspections and NDT of pipeline welds

Project Results

Groundbreaking for the dam and reservoir took place in 2021, with completion estimated for 2026. Lake Ralph Hall will be one of the largest lakes built in the state of Texas in the past 30 years. The reservoir will help to prevent future water shortages for 29 communities in northern Texas. Lake Ralph Hall is expected to have a capacity of 59 billion gallons of water.
