Snake Creek Mining & Tunnel Co. v. Midway Irrigation Co.
Headline: Court upholds Utah rule protecting farmers’ early water appropriation, blocking a mining company from claiming tunnel-collected underground water and preserving irrigation supplies for downstream farms.
Holding: The Court affirms that under Utah law waters collected by a mining tunnel belong to an earlier irrigation appropriation and not to the mine owner, protecting the irrigation company's prior water rights.
- Protects long-standing irrigation claims against later mining captures of underground water.
- Prevents mine owner from selling tunnel-collected water that reduces river supply.
- Clarifies Utah law that percolating waters can be appropriated for irrigation from public lands.
Summary
Background
The mining company, incorporated in Delaware, owns a mountain mine and drove a 14,500-foot tunnel beginning in 1910 that intercepts percolating underground water and brings it to a portal where it flows into the stream. The irrigation company, incorporated in Utah, is a corporate agency of local farmers who long before the tunnel was driven, while the lands were public, appropriated the stream’s natural flow and have used those waters to irrigate downstream arid lands. The mining company has not used the intercepted water but planned to sell rights to it; the tunnel materially diminished the underground supply that fed springs and the stream.
Reasoning
The Court considered whether Utah follows the common-law rule that percolating underground water belongs to the landowner, or whether earlier appropriations on public lands reach underground sources. Reviewing Utah decisions and territorial and congressional enactments, the Court held Utah never adopted the common-law rule for its arid conditions. The Court relied on early and later Utah cases that recognized appropriations of surface and underground sources on public lands and clarified that prior appropriations include those underground sources. It concluded the Circuit Court of Appeals correctly gave the irrigation company the superior right.
Real world impact
The decision protects irrigation appropriations made when the lands were public and prevents a later mine owner from claiming tunnel-intercepted waters that reduce the stream’s supply. Downstream farmers who relied on the water retain priority under Utah law. The ruling resolves conflicting state-court views and confirms that such water captures do not defeat prior irrigation rights.
