Permits & access
Permit required — see local rules.
  • Verify exact public access, current flow source and reach rules against CDFW and LADWP
  • SAFETY: the canyon descent and footing are the main risk — steep volcanic terrain
  • Flow is LADWP-managed and the gorge can see maintenance/flood diversions; not a turn-up-anytime river.
