Water Resources 

Local Supply 


The City of Frisco receives treated water from the North Texas Municipal Water District (NTMWD) which supplies water to approximately 1.6 million people in 13 member cities and 49 customer cities in seven counties.  
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 Raw Water Supply Project, commonly known as the "Wetland."

All of the reservoirs are owned by the United States Army 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. The NTMWD has water supply rights granted through permits by the State of Texas for use of the stored water in these reservoirs.

Current Reservoir Levels

The Texas Water Development Board (TWDB) provides information on current reservoir levels.
As a result of changes in reservoir levels brought about by the rains from Spring 2015, Frisco City Council voted unanimously to approve an ordinance updating our Water Management Plan with Best Management Practices (BMPs) for the long-term protection of our water supply. Learn more about the updated Water Management Plan.

Rainfall events tend to be cyclical in our region. While lake levels have increased dramatically from the rains during Spring 2015, it remains important that the City of Frisco and its water customers continue to use water wisely and preserve our precious resource for the long-term protection of our community.

NTMWD Long Range Water Supply Plan

The population of the NTMWD service area is expected to more than double between the years 2010 and 2060 from 1.6 million to an estimated 3.8 million served. To meet the treated drinking water needs of the service area through 2060, the NTMWD has identified numerous water management 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. More than 22 percent of the total future supplies are estimated to consist of conservation and reuse water 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 the NTMWD to extend current water supplies, these strategies alone will not be sufficient to support the expected rapid growth of the NTMWD service area.

The NTMWD holds water rights in Lavon Lake for 118,000 acre-feet/year. It is anticipated that to serve future needs through 2060, the NTMWD will need to add an additional source of raw water supply equal to the capacity of Lavon Lake (118,000 acre-feet/year) every decade for the next five decades. The NTMWD has secured additional raw water supplies to meet the projected growth through approximately 2020, including the recently completed East Fork Raw Water Supply Project (Wetland) which provides the NTMWD with approximately 102,000 acre-feet/year, and the additional supplies obtained through a contract with the SRA for 50,000- 80,000 acre-feet/year from Lake Tawakoni.

The NTMWD has initiated the permitting process for the proposed Lower Bois d’Arc Creek Reservoir, which will provide a total of 123,000 acre-feet/year of future raw water supplies including treatment and distribution to parts of Fannin County. 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. Reservoir planning and environmental studies have commenced, and construction of the proposed reservoir is tentatively scheduled for completion by 2020.
