Wyo. Stat. § 41-4-502
On receipt of an application for a permit to acquire the right to the beneficial use of the public water of the state of Wyoming, which application shall be on a form prescribed or designated by the state engineer, it is the state engineer's duty to date the application and to make a record of receipt of the application in his office. It is the state engineer's duty to examine all applications to ascertain that they contain all the necessary information to show the location, nature and amount of the proposed beneficial use. If the proposed beneficial use is for irrigation purposes, the application shall give the total acreage to be irrigated and the acreage in each legal subdivision of land proposed to be irrigated. If, upon such examination, an application submitted in hard copy is found defective, it is the duty of the state engineer to return the application for correction, with reasons therefor, and the time allowed within which to make such corrections, which shall not be less than ninety (90) days, shall be endorsed on the application, or by correspondence accompanying the return of the application, and a record made thereof. A like record shall be kept of the date of the return of corrected applications, and of the date of the refusal and return of applications rejected. If the application is submitted in hard copy, the defective application shall be returned by United States postal service or by other generally accepted mail delivery method to the postoffice address given by the applicant. If the application is submitted electronically, the defective application shall be returned electronically. If, at the expiration of the time allowed within which to make such corrections, the application has not been returned to the office of the state engineer with the corrections properly made, it is the duty of the state engineer to cancel the filing covered by the application. The state engineer, if in his opinion an extension is justified, or, upon request by the applicant for good cause shown, shall grant extensions of time for making corrections. However, extensions will not be granted if the request for the extension is received after the expiration of the time period the applicant seeks to extend.
