Underground water contested case hearings.

HB 136 clarifies that applicants seeking underground water rights must prove their case in contested hearings, shifting the burden of proof from the state engineer to the applicant. It requires applicants to demonstrate four specific conditions: unappropriated water availability, adequate diversion methods, compliance with well spacing rules, and non-detriment to public interest. This bill directly affects individuals or entities applying for or amending underground water rights in Wyoming, such as agricultural users or land developers. The law applies to all such applications filed on or after July 1, 2022, and modifies existing water rights procedures under Wyoming Statute 41-3-932.
