Surface Water - Surface waters are open to appropriation if unappropriated sources with adequate supply and quality can be found. Most known sources of useable size have been appropriated.

Ground Water - Ground water is open to appropriation. New filings are reviewed on their individual merits with emphasis on the potential for interference with existing rights. Suitable quality may be a problem in some areas.


Applications are advertised in the Tooele Transcript or the Nephi Times-News. Filings that may involve the diversion of water in Utah for use in Nevada (export) would be subject to the special criteria the statutes require for such projects. The general irrigation diversion duty for this area, which the State Engineer uses for evaluation purposes, is 4.0 acre-feet per acre per year. The consumptive use requirement is determined from the publication Consumptive Use of Irrigated Crops in Utah, Research Report 145, Utah State University, 1994, unless the applicant submits other data for consideration. This area is administered by the Weber River Regional Office in Salt Lake City.

Other requirements

The Water Right applicant is strongly cautioned that other permits may be required before any physical development of a project can begin and it is the responsibility of the applicant to determine the applicability of and acquisition of such permits. In order to avoid delays and ensure that Water Right approvals conform to applicable local ordinances, applicants should contact local governmental entities in advance to determine what ordinances are in place that affect the proposed project and to make sure that Water Right filings conform to those ordinances. The approval of a Water Right application does not imply any approval of a project by any other governmental entity. Approval of the project proposed in the Water Right application should be obtained from local governmental entities as necessary to implement a project.
