Water Rights

Rights Verified

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: Idaho
