LCRA manages the Highland Lakes and Colorado River as a system to supply water for more than 1 million people as well as businesses, industries, the environment and, when available, agriculture in the lower Colorado River basin.
LCRA has the rights to more than 2.1 million acre-feet of water per year. These rights – based mostly on surface water permits issued by the state of Texas – include the right to divert and use up to 1.5 million acre-feet per year from lakes Buchanan and Travis and 636,750 acre-feet per year under downstream run-of-river water rights from the Gulf Coast, Lakeside, Garwood and Pierce Ranch irrigation operations.
New water supplies
In 2012, LCRA set a goal of increasing its water supply by 100,000 acre-feet by 2017. Several
new water supply projects are underway to meet the goal, including a new reservoir in Wharton County and groundwater wells in Bastrop County.
Firm and interruptible customers
Water supplies managed by LCRA are divided into firm and interruptible water. Firm water is available even during a severe drought. Cities, industries and electric power plants rely on firm water supplies. During water shortages, interruptible water, which is mostly used for agriculture, is cut back or cut off. LCRA sells water to customers through
contracts and resolutions approved by LCRA's Board of Directors.
A managed water system
During severe dry periods, the lower Colorado River may flow at greatly reduced rates and levels in lakes Travis and Buchanan may drop. The Highland Lakes Overview page has more information about current conditions on the Highland Lakes.
LCRA manages lakes Travis and Buchanan under a state-approved
Water Management Plan, which describes how to allocate water during water supply shortages. It directs LCRA when to cut back or cut off interruptible water supplies so that demands for firm water can be met. The Water Management Plan also determines the amount of water available for environmental flows, which contribute to the health of the lower river and the bays and estuaries downstream of the Highland Lakes.
