The Oklahoma Regional Water District Act establishes a framework for the creation and management of regional water districts in Oklahoma, aimed at improving water resource management and planning. The Oklahoma Water Resources Board is tasked with designating these districts by July 1, 2026, taking into account various factors such as river basins, socioeconomic characteristics, and public input. Each district will be responsible for developing a regional water plan that addresses water resource management, conservation, and drought response, ensuring that sufficient water is available for public health, safety, and economic development. The Board will provide guidelines and technical assistance for the development of these plans, which must be submitted for approval and included in the Oklahoma Comprehensive Water Plan.

Additionally, the bill amends existing laws to ensure that updates to the Oklahoma Comprehensive Water Plan incorporate contributions from the newly formed regional water districts. It also enhances the Oklahoma Flood and Drought Management Task Force's responsibilities by including coordination with regional water districts and mandates the Oklahoma Water Resources Board to prepare a comprehensive state flood plan that accounts for the development of these districts. The act is set to take effect on November 1, 2025, and includes provisions for conflict resolution and public participation in the planning process.
