The authorization for this petition and provisions are found in W.S. 41-3-104. The following information is required:
a. HEADING - Show sufficient description and identification of the appropriation or appropriations to be changed.
b. OPENING STATEMENT - Identify the petitioner, and give a mailing address and a general introduction.
c. BODY
Item 1 - Indicate whether the petitioner is the sole or part owner of the appropriation and all or part of the lands described in the appropriation, and has provided the necessary proof of ownership.
Item 2 - Describe in complete detail the appropriation which will be affected by the petition by showing the name of the original appropriator, proof number, stream, ditch, permit number, and Certificate Record Book and page number.
ITEM 3 - Delineate the lands under the appropriation by 40-acre subdivision which are actually irrigated or proposed to be irrigated.
ITEM 4 - Give sufficient reason for the requested change.
ITEM 5 - Fees are required for a petition of this type (see Board Fee Schedule).
ITEM 6 - State conclusively whether or not any other appropriations from the same source of supply will be injured in any way.
ITEM 7 - State that the required map accompanies the petition. The map shall show the location of the ditch and the lands irrigated therefrom. The lands proposed to be excluded and the lands proposed to be included shall be shown on the same map by different cross-hatching.
d. PRAYER - State what is desired to be accomplished by the petition.
e. If the proposed change concerns lands now owned by another, the owner's written consent should accompany the petition. If consents cannot be obtained, a hearing may be held.
f. A petition may also be filed when lands with attached adjudicated water rights have become seeped or otherwise unfit for production of crops by irrigation, and it is the desire of the appropriator to change the land description in the certificate of appropriation by excluding these lands and substituting other suitable lands of equal or less area in lieu thereof. The amended area may not exceed the area actually irrigated under the original water right.
g. A hearing may be required for petitions where the re-description of the appropriation includes lands not in the original description of the appropriation, except in the case of simple clerical error.
h. This type of petition is also used to re-describe territorial "blanket descriptions" and court decree water rights so as to reflect on the record the actual diversion on the ground. Typically, this type of petition must be filed before lands can be sold, since the buyer wants to know exactly where the water rights are located. This type of petition may also be necessary in situations involving a change to a preferred use.
i. Petitions may not be approved which would activate a water right, which has not been exercised for at least five years when water has been available for use.
j . Petitions to change the place of use of ground water appropriations must be accompanied by copies of the pumping power or other records for at least five years prior to the petition filing date.
