Brazos Watermaster

The Brazos Watermaster Program administers water rights in the Brazos River basin downstream of, and including, Possum Kingdom Lake.

Jurisdiction

The Brazos Watermaster Program is responsible for an area that encompasses 41 in central and east Texas.

        River Basin                                                                               Counties
Brazos River Basin downstream and including Possum Kingdom Lake Austin, Bastrop, Bell, Bosque, Brazoria, Brazos, Brown, Burleson, Burnet, Callahan, Comanche, Coryell, Eastland, Erath, Falls, Fayette, Fort Bend, Freestone, Grimes, Hamilton, Hill, Hood, Jack, Johnson, Lampasas, Lee, Leon, Limestone, Madison, McLennan, Milam, Mills, Palo Pinto, Parker, Robertson, Somervell, Stephens, Travis, Waller, Washington, and Williamson

Five field deputies patrol these counties from offices located in Stephenville, Waco and Angleton. Water-right management is based on “run of the river rights.” That means the deputies oversee a constantly changing, dynamic surface-water system of rivers and tributaries that allow diversions as water is available and as it passes individual diversion points.

Duties of the Watermaster

Duties include:

  • allocating water per the adjudicated water rights
  • monitoring stream flow, reservoir levels, and water use within the basin
  • enforcing compliance with water rights
  • responding to complaints

The watermaster will also oversee situations where a diversion would remove water that rightfully belongs to another user. In that case the watermaster could, if needed, notify the user with lower priority to reduce or stop pumping. When streamflows diminish, the watermaster will allocate available water among the water right holders according to each user’s priority date.

Water Diverters Responsibilities

A diverter is any water right holder, agent, or contractual buyer who impounds, takes, diverts, or transports water in a watercourse, or makes a dedicated release of state water. Diverters in the watermaster area will be responsible for:

  • Installing a measuring device
  • Notifying the watermaster before diverting water
  • Submitting a report when pumping is completed
  • Complying with the rules of the Commission

Fees for Water Right Holders

Water right holders will be required to pay an annual fee. Each account will be assessed a base fee (currently $50) plus a use fee based on the type of use and amount of water authorized in the permit.
