HB 4459 Oklahoma House · 2026 Regular Session

Waters and water rights; metering of wells; requiring Water Resources Board provide certain allocation of groundwater; permits; requirements; measurements; effective date.

HB 4459 allows groundwater irrigation districts or conservation districts to create metering programs for farmers, enabling certified participants to apply for a five-year flexible water allocation. This directly affects farmers in participating districts who can temporarily exceed their annual water limit by up to 200% in a single year, as long as their total usage over five years stays within the basin's overall allocation. To qualify, participants must submit annual metering certifications from their district and pay an annual fee. The bill also states that exceeding the 200% annual limit or five-year total triggers penalties for unauthorized water use, as outlined in existing law.
