Clarification of existing state ownership of groundwater.

Wyoming's SF 81 clarifies that the state owns all underground water within its boundaries, as established by the state constitution. The bill preserves existing water use rights for well owners (for irrigation, municipal, or industrial purposes) but requires registration of wells with the state engineer by specific deadlines. It mandates permits for new well construction after July 1, 2022, while allowing existing "exempt" wells to register before December 31, 1972. The bill is declaratory - clarifying current law without altering existing water rights or creating new restrictions.
