What is Lake Ralph Hall?
Lake Ralph Hall will be the newest lake and one of the state's biggest projects to be built in nearly 30 years. The new lake will be located on the North Sulphur River near Ladonia in Fannin County. It will provide a safe, reliable water supply for some 29 communities that Upper Trinity Regional Water District (UTRWD) serves in North Texas region.
Construction on the lake is scheduled to begin in early 2021 with water delivery by 2025. Once complete, it will hold a maximum of 180,000 acre-feet of water (about 58.7 billion gallons) and will provide residents of Denton and Collin counties with up to 54 million gallons of additional water daily, including:
35 million gallons daily (MGD) of raw water
19 MGD of reuse water
UTRWD holds a water rights permit issued by the Texas Commission on Environmental Quality in December 2013. In January 2020, UTRWD received a Section 404 (Clean Water Act) permit from the the U.S. Army Corps. of Engineers.
