Must-know rules

  • Riparian: land touches a river/stream — reasonable use, rights run with the land
  • Littoral: land borders a lake/ocean — own to the high-water mark
  • Prior appropriation (arid states): first permit to divert wins — 'first in time'
  • Accretion adds land gradually; erosion removes it; avulsion = sudden change (boundaries stay)
  • Water rights are appurtenant — they transfer with the deed unless reserved
