Utah Supreme Court
Can water appropriators claim rights to underground sources that feed their surface waters? Salt Lake City v. Silver Fork Pipeline Corporation Explained
Summary
Salt Lake City sued Silver Fork Pipeline Corporation to quiet title to approximately 0.5 cubic feet per second of percolating water intercepted in the Kentucky-Utah Mine that was naturally tributary to Big Cottonwood Creek. The trial court quieted title in Salt Lake City based on its nearly complete appropriation of Big Cottonwood Creek waters under the Morse Decree, finding the mine waters were naturally tributary to the creek and that SFPC failed to establish valid diligence or adverse possession claims.
Analysis
The Utah Supreme Court’s decision in Salt Lake City v. Silver Fork Pipeline Corporation provides crucial guidance on water appropriators’ rights to underground sources that naturally feed their surface water appropriations. This case demonstrates how established surface water rights can extend to protect tributary groundwater sources.
Background and Facts
Salt Lake City held extensive water rights to Big Cottonwood Creek under the 1914 Morse Decree, controlling between 90-99% of the creek’s flow. Silver Fork Pipeline Corporation diverted approximately 0.5 cubic feet per second of percolating water from the Kentucky-Utah Mine tunnel to serve residential cabins. The mine intercepted underground water that would naturally flow into Big Cottonwood Creek absent the mine’s presence. When the state engineer threatened enforcement action, SFPC filed diligence and change applications, prompting Salt Lake City to seek quiet title to the mine waters.
Key Legal Issues
The court addressed whether Salt Lake City’s surface water appropriation included rights to underground tributary waters intercepted at the mine, and whether SFPC could establish superior rights through diligence claims or adverse possession. The analysis required determining if the mine waters were naturally tributary to Big Cottonwood Creek and whether interception substantially interfered with Salt Lake’s appropriation.
Court’s Analysis and Holding
The court affirmed that water appropriators hold vested interests in source waters that naturally feed their appropriations. Through extensive expert geological testimony, the court found the mine waters were naturally tributary to Big Cottonwood Creek and that diverting 0.5 c.f.s. (approximately 362 acre-feet annually) constituted substantial interference with Salt Lake’s rights. The court rejected SFPC’s claims, finding insufficient evidence of pre-1935 beneficial use required for diligence rights and failure to establish the hostile, continuous use necessary for adverse possession.
Practice Implications
This decision reinforces that surface water appropriations can extend to protect underground sources when they are naturally tributary and interference is substantial. Practitioners should rely on expert hydrogeological testimony rather than empirical flow measurements to establish tributary relationships, as such measurements may be unavailable or unreliable. The case also demonstrates the high evidentiary burden for establishing pre-1935 diligence claims and the importance of documenting clear chains of title in water rights disputes.

Court
Utah Supreme Court
Case Number
No. 980203
Date Decided
January 7, 2000
Outcome
Affirmed
Holding
An appropriator of surface water rights also owns a vested interest in the sources of those waters, including percolating waters that are naturally tributary to the appropriated surface water, when diversion of those source waters substantially interferes with the appropriator’s rights.
Standard of Review
Correctness for conclusions of law; clearly erroneous for findings of fact
Practice Tip
When asserting water rights to underground sources, establish the natural tributary relationship through expert geological and hydrological testimony, and document substantial interference with existing appropriations through evidence of water volume rather than requiring before-and-after flow measurements.
