Water and water rights; establishing procedures for permitting, monitoring, and reporting of groundwater use; making an appropriation to the Oklahoma Water Resources Board. Effective date.

SB 259 requires groundwater permit holders to annually report their water usage by January 31, including specific details about swine operations using liquid waste systems and whether they are licensed under Oklahoma's Concentrated Animal Feeding Operations Act. The Oklahoma Water Resources Board must investigate waste complaints, notify landowners before inspections, and implement a phased metering system for groundwater monitoring. The bill also prohibits water waste (like unpermitted use or inefficient practices), imposes fines for noncompliance, and appropriates funds to the Board for data collection and rulemaking. These changes directly affect groundwater users, especially agricultural operations, and expand the Board's oversight role.
