Our Water Supply

Local Supply

The City of Frisco receives treated water from the North Texas Municipal Water District (NTMWD) which supplies water to approximately 2 million people in about 80 communities in 10 counties, and our region is expected to double in size by 2050.

Five surface water supply sources make up the NTMWD reservoir system that supplies our treated drinking water. The primary source is Lavon Lake with additional sources that include Jim Chapman Lake, Lake Texoma, Lake Tawakoni, and the East Fork Reuse Project, commonly known as the Wetland.

All the reservoirs are owned by the United States Corps of Engineers which has the full authority to operate, maintain, and release water for flood control at its reservoirs used in the NTMWD service area. NTMWD has water supply rights granted through permits by the State of Texas for use of the stored water in these reservoirs. View the current reservoir levels on the Texas Water Development Board website.

NTMWD Long Range Water Supply Plan

NTMWD services 90 communities in 10 counties. Currently the district services about 1.7 million people and expects that population to more than double by 2070.

To continue meeting the treated drinking water needs of the service area through this period, NTMWD has identified numerous strategies and projects to generate additional water supplies. These strategies include using current supplies, connecting to existing supplies, developing new reservoirs, and making use of supplies from conservation and reuse strategies.

Conservation is by far the most economical water supply strategy identified when compared to all other strategies. It is imperative to recognize that even if target conservation and reuse goals are successfully met, allowing NTMWD to extend current water supplies, these strategies alone will not be sufficient to support the expected rapid growth of the NTMWD service area.

To continue meeting the increasing demands on our water supply, NTMWD completed the permitting process for the Bois d'Arc Reservoir on February 2, 2018. The project is expected to be completed in 2022.

The reservoir will also supplement supply for other NTMWD member cities and customers, and will provide an added benefit of recreational opportunities such as boating and fishing. For more details, view the district's plan for meeting future supply needs.
