Dana Point Harbor Jetty (long west breakwater)

The long jetty is a continuous rock pile with a protected harbor-facing flank and an exposed ocean-facing flank. The outer end meets the two-breakwater entrance, where NOAA's Coast Pilot gives an entrance depth of about 20 ft. NOAA's Bathymetric Data Viewer, the NCEI Dana Point hydrographic survey archive and the USGS Southern California 1-m topobathymetric model are the appropriate next sources for point soundings; this draft does not assign approximate depths because I did not extract a defensible sounding at each zone.

• Channel-facing flank · mixed drop
  rock into a slope, moderate snag risk

  Harbor-facing base beside the Ocean Institute/headlands access. Riprap meets protected harbor water; exact toe depth not confidently resolved from the available bathymetry documentation.

• Channel-facing flank · mixed drop
  rock into a slope, moderate snag risk
  Vessel traffic

  Sheltered flank beside the harbor basin and approach channel. Use the visual rock edge as structure, not as a depth contour; vessel traffic is a practical hazard.

• Channel-facing flank · deep water
  deep water at the rocks, less exposed but harder to free gear

  At the outer entrance, NOAA's Coast Pilot describes approximately 20 ft between the two breakwaters; no zone-specific point depth is claimed here.

• Ocean-facing flank · shallow boulder
  shallow rock, highest snag risk — worse as the tide drops

  Near the headlands/base access, exposed rock and tide-pool/beach transition dominate. This is the shallowest visual character, but no numeric depth is asserted.

• Ocean-facing flank · mixed drop
  rock into a slope, moderate snag risk

  Long seaward flank with a rock-to-open-water edge and no confidently extracted point sounding. Local reports identify this mid-to-two-thirds section as the strongest structure-fishing water.

• Ocean-facing flank · deep water
  deep water at the rocks, less exposed but harder to free gear
  Wave run-up

  Outer tip is adjacent to the documented ~20-ft entrance, but swell and current can make the same rock unsafe to fish; do not interpret the category as a safety recommendation.

• Outer tip · deep water
  deep water at the rocks, less exposed but harder to free gear

  Planning grid off the lighted tip. Category is based on the Coast Pilot's entrance description; numeric depth omitted because the source does not provide a tip-centered sounding.
