REQUIREMENTS FOR GRANTINGWATER RIGHTS PERMITS

TEXAS WATER CODE §11.134

… (b) The commission shall grant the application only if:

(1) the application conforms to the requirements prescribed

by this chapter and is accompanied by the prescribed fee;

(2) unappropriated water is available in the source of supply;

(3) the proposed appropriateion:

(A) is intended for a beneficial use;

(B) does not impair existing water rights or vested riparian rights; ….

SENATE BILL 1of the 75th Texas Legislature

Article 7, Section 7.01

Requires TNRCC to obtain or developupdated Water Availability Models for:

• Six River Basins by December 31, 1999

• All Remaining River Basins by December 31, 2001

SENATE BILL 1of the 75th Texas Legislature

Requires TNRCC to provide the following results from the Water Availability Models:

1. For each Water Right, the projected amount of waterthat would be available during a drought of record and when flows are at 75 and 50 percent of normal

2. For each Regional Water Planning Group, the projected amount of water that would be available if cancellation procedures were instigated by TNRCC

3. In coordination with TPWD, the potential impact of wastewater reuse on existing water rights, instream uses, and freshwater inflows to bays and estuaries.

ACTIVITIES INVOLVED INWATER AVAILABILITY ANALYSES

1. Compilation and Organization of Data

2. Determination of Naturalized Streamflows (~ 50 Years of Monthly Values at Gage Locations)

3. Characterization of Existing Water Rights

4. Development of Water Availability Model

5. Operation of WAM for Different Scenarios (~ 50-Year Simulation Period)

6. Summary and Presentation of WAM Results

BASIC RESULTS FROMWATER AVAILABILITY ANALYSES

1. For Each Water Right,

• Simulated Monthly Diversions

• Simulated Monthly Reservoir Storage

2. For Each Model Control Point,

• Simulated Monthly Unappropriated Water

• Simulated Monthly Actual Streamflows

WRAP-SIM MODELDEVELOPMENT

WRAP-SIMWATER AVAILABILITY MODEL

Sulphur River Basin

• Modified Version of Texas A&M WRAP Model

• Developed by Dr. Ralph Wurbs (Texas A&M)

• Simulates Unappropriated Water and Actual Streamflows in Response to Diversions and Reservoir Storage

• Incorporates Prior Appropriation Doctrine

• Tailored to Requirements of Senate Bill 1

SPECIAL FEATURES OF WRAP-SIM WATER AVAILABILITY MODEL

Sulphur River Basin

• Distributes Gaged Naturalized Streamflows

• Simulates Off-Channel Reservoir Operations

• Provides for Minimum Instream Flows

• Accounts for Streamflow Channel Losses

• Allows Specification of External Gains/Losses

• Allows Monthly-Varying Conservation Storage
