This earth dam stands at a height of 33 feet and has a length of 931 feet, providing storage for 293 acre-feet of water and covering a surface area of 4.5 acres. Despite being categorized as having a fair condition assessment as of April 2021, the dam has a moderate risk level and is regulated by the Texas Commission on Environmental Quality (TCEQ).
With a primary purpose of flood risk reduction, the East Fork Dam also serves fire protection, stock, small fish pond, and recreational purposes. It features an uncontrolled spillway with a width of 54 feet and outlet gates for water release. The dam plays a crucial role in managing water resources in the region, with a maximum discharge capacity of 599 cubic feet per second. As climate change continues to impact water availability and extreme weather events, monitoring and maintaining the structural integrity of dams like East Fork become increasingly important for ensuring community safety and water security.
