Oklahoma House Bill HB4350

Oklahoma 2026 Regular Session

• Introduced: 2/2/26
• Refer: 2/3/26

Caption

Waters and water rights; authorizing the Oklahoma Water Resources Board to implement certain allocation to encourage conservation after certain date; effective date.

Summary

HB4350 amends Oklahoma’s groundwater permitting and metering law to create a new “five-year flex allocation” program beginning January 1, 2027. Under the bill, the Oklahoma Water Resources Board would be authorized to require metering of water wells, approve the meters used, seal them, and inspect or read them at any time. Applicants participating in the flex allocation program would have to submit annual usage reports from a Board-approved measurement system and pay the annual groundwater permit fee. The bill allows permit holders to manage groundwater use over a five-year period rather than being limited strictly to a single year’s allocation, so long as they do not exceed the basin’s cumulative allocation over the five years. It applies to existing permit holders, new applicants, and certain temporary permit holders, and it specifically states that no new permit is required for existing permit holders. The bill also caps any single year’s overage at 200% of the annual allocation and exempts domestic wells from its requirements. The act would take effect November 1, 2026.

Impact

HB4350 would modify 82 O.S. 2021, Section 1020.19, by adding a conservation-oriented groundwater allocation framework and expanding the Oklahoma Water Resources Board’s authority over well metering and reporting. It would affect groundwater permit holders in basins and subbasins statewide, while leaving domestic wells outside the new requirements. The bill would change how water rights and usage are administered by allowing more flexible annual use within a five-year cumulative limit, potentially affecting agricultural, municipal, and other non-domestic groundwater users.

Sentiment

Based on the bill text and available legislative history, the measure appears to be framed as a conservation and management tool rather than a punitive restriction. The caption and statutory changes emphasize encouraging groundwater conservation and giving permit holders flexibility in how they use their allocations over time. No committee transcript or vote record is available here to show direct debate, but the bill’s structure suggests a generally policy-driven, administrative approach.

Contention

The main points of potential contention are the Oklahoma Water Resources Board’s expanded authority to require meters, inspect wells, and enforce reporting, as well as the practical limits on how much a permit holder may exceed annual allocations in any one year. Water users who prefer more local control or less regulatory oversight may object to mandatory metering and reporting, while conservation advocates may support the bill’s attempt to manage groundwater more sustainably. Another possible issue is how the five-year flex allocation would interact with existing permit expectations and basin-specific yield determinations, especially in areas where maximum annual yield has not yet been established.
