Great Basin Deep Fossil Aquifer — Western Utah

Millard, Utah, USA

Deep basin-fill and carbonate aquifers beneath western Utah's Great Basin. Pleistocene pluvial Lake Bonneville recharged deep aquifer systems 10,000-30,000 years ago. Modern recharge is minimal in this arid region. Large springs (including Fish Springs and Blue Lake) discharge ancient water from deep carbonate formations.

Water Rights

Unverified

Prior Appropriation

First in time, first in right

Rights are established by historical beneficial use. Senior rights holders receive full allocation before junior holders, regardless of land ownership.

  • Seniority date determines priority order
  • Requires continuous beneficial use
  • Can be severed from land and transferred
  • "Use it or lose it" — abandonment risk
Common in western US states (CO, MT, WY, ID, NV, UT, AZ, NM, OR, WA, CA)• Asset location: Utah

Rights status, seniority, transferability, and enforceability vary by jurisdiction and change over time. Always consult a licensed water rights attorney and verify status with the relevant state water resources agency before any acquisition or use decision.
