037-2 Wyo. Code R. § 2-9
Domestic and stock wells completed prior to May 24, 1969, may be registered with the State Engineer on Form U.W. 7 - "Statement of Completion and Description of Well". Such registration is not compulsory; but in cases of conflict between water users, registration will be required to show priority dates and information on well construction. All existing domestic or stock wells which were properly registered prior to December 31, 1972, will have a priority as of the date of completion of the well. Existing wells registered after December 31, 1972, will have a priority as of the date of filing with the State Engineer's Office. Each well must be filed on a separate form, and the Two Dollar ($2.00) filing fee must accompany each registration.
