Project Construction

Roadway Relocations / Improvements and New Pedestrian-Friendly Bridge

Improvements and closures to certain county roads within the project area. Construction of a new, pedestrian-friendly SH 34 lake bridge and the relocation of a portion of Hwy 1550.

Untreated Water Pipeline and Balancing Reservoir

32 mile pipeline and balancing reservoir will deliver water to Upper Trinity’s water system for treatment and transmission to its customers.

Administration, Operation and Maintenance Facilities

Facilities related to the lake’s day-to-day operation, management and maintenance. A visitors’ center will be located at the administration office on Hwy 34.

Watershed Protection Areas

Areas left in their natural condition to protect water quality in the lake.

Reservoir – Leon Hurse Dam, Spillway and Intake Pump Station

Owned and operated by Upper Trinity, the new reservoir will provide an additional 35 million gallons daily (MGD) of water. The intake pump station will withdraw water from the new lake and pump it into the untreated water pipeline.

Ladonia Fossil Park Relocation

One of Ladonia’s most popular tourist attractions, the fossil park, will be temporarily located on Hwy 2990 during construction, and a new fossil park will be constructed downstream of the Leon Hurse Dam on Hwy 904.

Mitigation

Includes returning a portion of the North Sulphur River back to its natural, meandering path.

The Lake Ralph Hall Construction Project

  • A dam, spillway and lake intake

  • 32 miles of untreated water pipeline and balancing reservoir

  • Roadway relocations/improvements and a new lake bridge

  • Lake office and maintenance facilities

  • Environmental improvements in specific areas around the lake, including restoring portions of the original river channel

  • Relocation of Ladonia Fossil Park to a new downstream location site still to be determined
