037-5 Wyo. Code R. § 5-5
a. Petition maps must be on good quality tracing linen or an acceptable equivalent. All maps to be filed in the office of the State Board of Control shall conform with the Regulations and Instructions of the State Engineer's Office. Particular attention shall be accorded the land grid which is used on maps accompanying petitions, which shall agree with the current U.S. Government survey plat as to lotting and other subdivision identification. Sufficient information should be placed on the map to clearly show what is proposed in the petition. This can be done by use of a proper map title, a detailed map legend, proper land ownership and explanatory notes and labels as needed.
b. The same map used for an application for permit to the State Engineer and/or a petition to the State Engineer may accompany a petition to the State Board of Control when it is feasible to show all the required information on one map. In such a situation, the map title shall reflect that the map supports two or more proposals by identifying each in detail. The original shall be filed with the State Engineer, while a paper print may be filed with the State Board of Control.
c. All maps in support of petitions must bear the certificate of a professional engineer or professional land surveyor licensed to practice in Wyoming.
d. Maps shall be prepared from field notes and a survey and shall reflect the true conditions on the ground. The survey may be supplemented by information from aerial photographs and the records of the State Board of Control and State Engineer. However, such supplemental information is not to be substituted for a survey made on the ground. Because most petitions to the State Board of Control deal with lands which are irrigated in whole or in part, the certificate should reflect what lands shown on the map are in fact irrigated. A statement that lands have been irrigated, or could be irrigated, or are irrigable, is not acceptable. The Board must know the true situation on the ground which exists at the time the map is prepared. For example, if part of the lands in the original adjudication lie above a ditch and have not historically been irrigated, or are not now being irrigated, the map should portray this situation, which should also be reflected in the certificate. The same type of information is generally required when ground water appropriations are involved.
e. Maps must not be folded.
f. If a special situation arises which does not appear to be compatible with the map requirements outlined above, specific written permission from the ex-officio secretary of the Board should be obtained in order to deviate from these map requirements. Such a permission letter must be transmitted with the petition and map when they are filed.
g. When a delivery system (means of conveyance) becomes so complicated in the view of the division superintendent that it hampers water administration, the division superintendent may require that a petition to describe or change the means of conveyance be filed.
h. All maps which accompany petitions for change of water rights shall:
i. Computer generated maps are acceptable with an original seal and signature within the certificate of a professional engineer or professional land surveyor.
