Bill > HB4350

This bill, effective November 1, 2026, amends existing Oklahoma law regarding water rights to encourage groundwater conservation by authorizing the Oklahoma Water Resources Board (OWRB) to implement a five-year "flex allocation" program starting January 1, 2027. This program allows existing and new permit holders for groundwater use in designated basins or subbasins to have a flexible annual allocation, meaning they can exceed their determined annual limit in any given year as long as their total usage over the five-year period does not surpass the cumulative allocation for that basin or subbasin, with a cap of not exceeding the annual allocation by more than 200% in any single year. To participate, applicants must submit annual usage reports from an OWRB-approved water measurement system and pay the annual groundwater permit fee; however, domestic wells are exempt from these provisions.
