      <p>In 1913, the Board of Railroad Commissioners was made ex officio the newly created Montana
        Public Service Commission. In 1919, the Board also was made ex officio the Montana
        Irrigation Commission and the Montana Trade Commission. The Irrigation Commission assisted
        in organizing and management of irrigation districts around the state. It also had
        jurisdiction over the sale of water, water rights, and the contracting of water for
        irrigation. The Montana Irrigation Commission was abolished in 1929.</p>

      <p>This collection consists predominantly of subject files (1919-1929) for irrigation
        districts around the state. The files include correspondence, petitions, legal documents,
        court papers, reports, and maps concerning the founding of the districts, plans for their
        developments, reports on their feasibility, and engineering reports. There are also project
        histories, arranged by district number; and project surveys arranged by county. </p>

      <p>In 2024, the various collections of the Montana Public Service Commission were integrated
        under one collection identifier, RS 501, in order to help facilitate access, reduce
        redundancy in the Montana Historical Society Library &amp; Archives catalog, and to follow
        best archival practices.</p>
      <p>Collections from Montana Public Service Commission's various Divisions and Predecessor
        Agencies that were previously treated as separate entities are now integrated into <emph render="bold">this collection, RS 501</emph>. Rather than reprocessing over 80 linear feet
        of PSC materials, MTHS staff decided to keep the past arrangement of those
        collections/finding aids and provide access to them via links in the primary finding aid.
        This decision has allowed the MTHS archival staff to maintain intellectual control over the
        collection, while removing the need to reprocess it. It also keeps State Agency finding aids
        at manageable sizes. Please read the scope and content note carefully to determine if this
        subgroup pertains to your research needs. </p>
