This brief paper describes a future water supply source for the members of the Upper Trinity Regional Water District. The proposed Lake Ralph Hall will provide about 30 million gallons of water per day (mgd), plus about 15 mgd in reuse for the Upper Trinity service area. Also, water will be available for the City of Ladonia and Fannin County. Though similar in size to Grapevine Lake, greater rainfall in the Sulphur River Basin will allow Lake Ralph Hall to yield about 20% more water. Economic and environmental benefits of Lake Ralph Hall are mentioned. A Good Site. Preliminary field studies confirm that the North Sulphur River near the City of Ladonia is a good site for a new water supply lake.
