House Bill No. 1807 amends existing water rights legislation in Oklahoma, specifically focusing on the metering of groundwater usage. The bill mandates that all permit holders authorized to extract groundwater must implement a system to measure their usage from all associated wells. The Oklahoma Water Resources Board is tasked with determining the acceptable measurement systems, which may include telemetry devices for monitoring. Additionally, the bill establishes that data from these measuring systems will be used for annual groundwater use reports, while clarifying that the Board cannot require a specific type of metering system.

To promote groundwater conservation, the bill introduces a five-year flex allocation for groundwater usage starting January 1, 2026. This allocation allows permit holders to exceed their determined annual allocation in any given year, provided they do not exceed a cumulative limit over the five-year period. The bill outlines requirements for applicants seeking this allocation, including the submission of an annual usage report and payment of a permit fee. Notably, the provisions do not apply to domestic wells, and the act is set to take effect on November 1, 2025.
