Water Supply

Where does Tarrant County’s water come from?

During a typical year, 80 to 85 percent of the water TRWD provides to its primary wholesale customers comes from Cedar Creek and Richland-Chambers lakes. The other 15 to 20 percent comes from Lake Bridgeport, Eagle Mountain Lake and Benbrook Lake. (Benbrook Lake is managed by the U.S. Army Corps of Engineers).

What does conservation level mean?

The amount of water an entity can impound at a reservoir under its Water Rights Permit. Once a reservoir fills its conservation pool, any water above that level must be discharged unless the water is being temporarily stored for routing flood waters.

Conservation Levels for TRWD Lakes:

  • Richland-Chambers 315.0
  • Bridgeport 836.0
  • Eagle Mountain 649.1
  • Cedar Creek 322.0

Conservation Levels for TRWD Lakes:

  • Arlington 550.0
  • Benbrook 694.0
  • Lake Worth 594.0
Does TRWD post information about water levels and pumping changes? 

Yes. TRWD posts this information daily. TRWD’s Daily Report is updated every 24 hours and lists the following data for TRWD lakes as well as Benbrook Lake, Lake Arlington and Lake Worth: Conservation Level, Lake Level, Change in Lake Level, Pumpage from Lake, Pumpage into Lake, Flood Discharge, Water Release and Evaporation.

But we have a reliable water supply, why should I protect/conserve water?

Water supplies are strained by growing populations and increasing demand. Each year, Texans spend more than $1 billion dollars on new or expanded water supply and wastewater treatment facilities. Water conservation not only saves money on your monthly water bill, it also minimizes future water shortages and costs. The district manages two water conservation campaigns: Save Tarrant Water and Water is Awesome.
