Mitigation & Watershed Areas
The North Sulphur River continues to experience extensive erosion problems that Lake Ralph Hall will help address. The local ecosystem will greatly benefit from the creation of the lake itself and associated environmental mitigation.
In the 1920s, the natural path of the North Sulphur River was straightened and channeled to help protect farmland along the river near the City of Ladonia from periodic flooding. The channel was originally created to be 16-20 ft. wide and 10 ft. deep. Since that time, massive erosion has expanded the channel to 350 ft. wide and over 60 ft. deep--nearly ten times its original size. Original wetlands, quality habitat and multiple state highway bridges have been destroyed in the process. Today, erosion continues to damage not only the North Sulphur, but also its connected tributaries.

There is no evidence that the channel is in the process of becoming stabilized or recovering. Lake Ralph Hall provides an opportunity to turn this environmental problem into a healthy asset – providing a rich aquatic and terrestrial habitat in Fannin County and water for future Texans. Once operational, the new lake will help mitigate erosion, provide new water and food resources for animals and provide better soil and natural resources.
As part of the lake project, a portion of the original North Sulphur River will also be restored to its beautiful and natural meandering path.
