In the Brazos River Basin, water supplies that are currently available on a long-term basis – even during drought – are fully allocated. Cities, farmers, ranchers, and industries already have spoken for this “firm water” - meaning they’ve obtained permits for it.

As a result, the lower basin of the river is increasingly at risk of water shortages:

  • During drought
  • If industry wants to expand
  • If upper basin users withdraw more water


Given these challenges, the Lower Brazos River Coalition supports the solutions listed below – and urges you to do the same.

Allens Creek Reservoir

The Coalition believes the City of Houston should sell its share of the proposed off-channel reservoir to the Brazos River Authority to move ahead with the project as soon as possible.

The Brazos River Authority, which owns 30% of the proposed reservoir, is considering its options following a December 2019 court ruling that invalidated a statutory requirement for Houston to sell.

Yield: Up to 100,000 acre-feet of firm water per year.

Milam County Groundwater and Alcoa Water Supply Project

The Coalition supports a proposal to develop water supplies from Lake Alcoa, Little River and groundwater sources in Milam County, as outlined in Brazos G’s 2021 Initially Prepared Regional Water Plan.

Yield: up to 18,600 acre-feet a year from Lake Alcoa and up to 17,529 acre-feet per year in groundwater.

Drought Contingency Plans

Drought Contingency Plans are required for most public water providers in Texas to guide operations in times of rainfall shortages.

These blueprints define stages of drought and responses that must be made to extend water supplies as long as possible.

The Coalition supports more rigorous use of Drought Contingency Plans to ensure fair and equitable distribution of water during shortages.

Brazos Watermaster Program

The Coalition supports the Brazos Watermaster Program, which is a state mechanism for overseeing compliance with water rights, rules and laws by monitoring stream flows, reservoir levels, and water use.

The Watermaster coordinates river diversions and regulates reservoirs to prevent water from being wasted or used in excess of a water right.

Lake Whitney Reallocation and/or Revised Drought Contingency Plan

The Coalition supports efforts to increase water supplies from Lake Whitney - in coordination with the Brazos River Authority, the U.S. Army Corps of Engineers, and the Southwestern Power Administration.

The Brazos River Authority is seeking reallocation of the existing water in Lake Whitney from hydropower to water supply, working through Region G Water Planning Group.

Yield: 20,842 acre feet per year from hydropower storage (2070 conditions).


The Lower Brazos River Coalition is interested in desalination, which is the process of removing dissolved solids and other minerals from saline water sources – both seawater and brackish groundwater.

This technology is used all around the world to produce new water supplies. In 2018, there were approximately 20,000 desalination plants (brackish groundwater and seawater) worldwide, with an equivalent installed capacity of 26.4 billion gallons per day (29.6 million acre-feet per year) (Sanz, 2018).
