Other Lakes

The other lakes we monitor for watershed planning and protection are: Lake Arlington, Lake Worth, and Benbrook Lake.

Benbrook Lake

Planning and initiatives
Benbrook Lake is located on the Clear Fork of the Trinity River in southwest Tarrant county and is owned and operated by the U.S. Army Corps of Engineers. The watershed is 429 square miles and drains portions of Tarrant, Johnson and Parker counties. Land use is still largely rural, but urban development is rapidly moving into several areas of the watershed.

In 1987, the Texas Water Commission granted TRWD a water rights permit for Benbrook Lake, which also allows the district to use the lake as storage for water piped in from Cedar Creek and Richland‐Chambers Lakes. Although TRWD doesn’t own or operate the reservoir, this action gave the district a vested interest in the quality of the water entering from the watershed.

Studies conducted in the Benbrook Lake watershed indicated future water quality impacts from increased wastewater flows due to the rapidly growing urban population. This information spurred TRWD to propose more stringent effluent limitations for new and amended municipal discharge permits issued in the watershed. In 2015 the TCEQ approved new rules which accomplished this goal. These new requirements are part of the Watershed Protection regulations in 30 TAC Chapter 311.
 

Lake Arlington

Planning and initiatives
Lake Arlington is located in southeast Tarrant County and is owned and operated by the city of Arlington, a major TRWD water customer. The lake is a “terminal storage,” or delivery point for water from TRWD’s eastern reservoirs to the city of Arlington and the Trinity River Authority. The 143 square mile watershed drains portions of Tarrant and Johnson counties and includes a patchwork of urban and rural areas including Burleson, Kennedale, and Fort Worth, while the shores of the lake are shared by Fort Worth and Arlington.
Urban areas dominate the northern end of the watershed, with a few industrial and municipal complexes near its center, and trending more towards agricultural use in the southern extent. Although inputs from TRWD supplies comprise a portion of the water in Lake Arlington, the lake is also influenced by water from springs, stormwater runoff and tributaries within the Village Creek watershed. In 2011 the city of Arlington developed a Master Plan for the lake, with the goals of protecting water quality and managing the increasing pressures of a growing population. This plan provides the foundation for a Watershed Protection Plan currently being developed by the Trinity River Authority, in conjunction with the city of Arlington and other jurisdictions and stakeholders in the watershed.

Lake Worth

Planning and initiatives

Lake Worth is located in western Tarrant county and is a major water supply for the city of Fort Worth. Situated just downstream of the Eagle Mountain Lake dam, Lake Worth’s water quality is influenced by flows from upstream, as well as an additional 85 square miles of watershed extending into portions of Tarrant and Parker counties. With the intent to protect water quality by reducing pollutant loads from the contributing area while enhancing recreational opportunities in the Lake Worth Watershed, the North Central Texas Council of Governments (NCTCOG) and The Trust for Public Land partnered to work with the City of Fort Worth and a local citizen advisory committee (The Lake Worth Regional Coordination Committee, the LWRCC) to develop a Greenprint for the lake.
