Court upholds water rights, decision on Lake Ralph Hall expected this fall

Officials with the Upper Trinity Regional Water District announced that today the administrative law judges for the State Office of Administrative Hearings recommended approval of the pending water rights permit for Lake Ralph Hall.

The review by the administrative law judges was necessary because the town of Flower Mound has opposed the lake’s construction. Lake Ralph Hall, which would be located in Fannin County, would become part of the district’s water supplies, the first new water supply lake to be built in Texas in two decades. But, as the district’s largest customer, the town of Flower Mound would pay the largest portion of the bill for the lake’s construction.

The Texas Commission on Environmental Quality is expected to make a final determination on Upper Trinity’s pending permit later this year.

Officials at Upper Trinity said the lake is the right size and can be completed in time to protect against a future water crisis by providing an additional 30 million gallons-per-day of water to North Texas customers. They claim Lake Ralph Hall would be the lowest-cost source of new water for district customers — the land has no cemeteries or oil and gas infrastructure.

Upper Trinity is a regional water district created by the Texas Legislature in 1989 and provides water and wastewater services to all of Denton County and portions of Dallas and Collin Counties.
