BACKGROUND
• The Texas Water Development Board (“TWDB”) administers 16 regional water planning areas as part of the state water planning process
• NTMWD participates in and is located in the TWDB Region C water planning area (“Region C”) and contributed to the development of the 2026 Region C Initially Prepared Plan
• On June 26, 2025, the Texas Water Development Board identified an interregional conflict between the 2026 Region C and Region D Initially Prepared Plans, and required the regional water planning groups to engage in mediation to attempt to resolve the conflict
• On August 1, 2025, the mediation resulted in the Agreement Resolving the Declared Conflict Between the Region C and Region D 2026 Initially Prepared Water Plans, which required two studies to be conducted that are related to the Marvin Nichols Reservoir (the “Agreement”)
• Regions C and D will conduct a joint study that will address the potential benefits and impacts of the Marvin Nichols Reservoir and the anticipated associated mitigation land acquisition on the economic, agricultural, and natural resources of Regions C and D (the “Joint Study”)
• Region C will solely conduct a study that will compare monetary and non-monetary elements and effects of the Marvin Nichols and Toledo Bend projects (the “Region C Only Study”)
• Region C appointed North Texas Municipal Water District (“NTMWD”), Tarrant Regional Water District, Upper Trinity Regional Water District, City of Dallas, and City of Irving (the “Parties”) to be members of an interregional working group, which will administer the Agreement along with members appointed by Region D
• The Parties will provide funding for fifty percent (50%) of the cost of the Joint Study, up to a two hundred and fifty thousand dollars ($250,000.00) maximum, and will share in the total cost of the Region C Only Study up to a one-hundred thousand dollars ($100,000.00) maximum
• NTMWD’s total combined contribution to the Joint Study and the Region C Only Study will be $83,175, and costs will be shared among the Parties for each study as follows:
o Region C contributions to Joint Study
■ NTMWD: $59,375.00 (23.75%)
■ TRWD: $59,375.00 (23.75%)
■ Dallas: $59,375.00 (23.75%)
■ UTRWD: $59,375.00 (23.75%)
■ Irving: $12,500.00 (5%)
o Region C contributions to the Region C Only Study
■ NTMWD: $23,750.00 (23.75%)
■ TRWD: $23,750.00 (23.75%)
■ Dallas: $23,750.00 (23.75%)
■ UTRWD: $23,750.00 (23.75%)
■ Irving: $5,000.00 (5%)
• NTMWD has been designated by the Parties as the entity to collect Region C’s funding in support of the Joint Study and to coordinate with Riverbend Water Resources District (“Riverbend”), which will be responsible for finding, hiring, and paying a consultant to conduct the Joint Study
• NTMWD has been designated by the Parties as the entity to collect Region C’s funding in support of the Region C only study and be responsible for finding, hiring, and paying a consultant to conduct the Region C Only study
