Elm Fork Trinity River near Lewisville

Can you imagine the Elm Fork Trinity River near Lewisville before the dams, when its flow was untamed? Before Lake Lewisville and Lake Ray Roberts, the Elm Fork and its tributaries like Denton Creek, Hickory Creek, and Clear Creek were the main water sources for Denton County. The late 1800s saw settlers grapple with the river’s unpredictable nature. Flooding in the spring would overflow cities and farms. The summer months, however, brought severe drought. This constant cycle of feast and famine made it clear that a more reliable water source was essential. By the 1920s, the decision was made to tame the Elm Fork. The construction of Lake Dallas, a reservoir on a tributary of the Elm Fork, began in 1928. The dam, a massive structure 80 feet high and 11,000 feet long, stood near Garza, a town later renamed Lake Dallas. The Elm Fork Trinity River near Lewisville played a pivotal role in providing water for the City of Dallas for 30 years. This sparked a debate between Dallas and Denton County. Dallas wanted to restrict recreational activities on the lake, fearing contamination of their drinking water. Denton County, promised recreational use, refused to prosecute anyone swimming in the lake. Denton County prevailed. Lake Dallas became a popular spot for recreation. Eventually, Lake Dallas merged with the Garza-Little Elm reservoir to form the expansive Lake Lewisville. Years later, in the 1980s, the Elm Fork Trinity River near Lewisville was again dammed. This time, it formed Lake Ray Roberts. This further altered the flow of the river, creating another reservoir to serve the water needs of Dallas and Denton. Today, the Elm Fork Trinity River near Lewisville flows below these dams, a testament to the region’s efforts to balance its water needs with the preservation of this natural waterway. Though changed, the river remains a vital part of the landscape. It sustains the surrounding ecosystem and offers recreational opportunities.
