NOTE A
Navigation regulations are published in Chapter 2, U.S. 
Coast Pilot 7.  Additions or revisions to Chapter 2 are 
published in the Notice to Mariners.  Information concerning the 
regulations may be obtained at the Office of the Commander, 
11th Coast Guard District in Alameda, California or at the 
office of District Engineer, Corps of Engineers in

AUTHORITIES
Hydrography and topography by the National Ocean Service, Coast 
Survey, with additional data from the U.S. Coast Guard.

WARNING - PRUDENT MARINER
The prudent mariner will not rely solely on 
any single aid to navigation, particularly on 
floating aids.  See U.S. Coast Guard Light List 
and U.S. Coast Pilot for details.

AIDS TO NAVIGATION
Consult U.S. Coast Guard Light List for supplemental information 
concerning aids to navigation.

POLLUTION REPORTS
Report all spills of oil and hazardous substances to the 
National Response Center via 1-800-424-8802 (toll free), or 
to the nearest U.S. Coast Guard facility if telephone 
communication is impossible (33 CFR 153).

RADAR REFLECTORS 
Radar Reflectors have been placed on many floating aids 
to navigation.  Individual radar reflector identification on 
these aids has been omitted from this chart.

CAUTION - TEMPORARY
Temporary changes or defects in aids to 
navigation are not indicated on this chart.  See 
Notice to Mariners.

SUPPLEMENTAL INFORMATION
Consult U.S. Coast Pilot 7 for important 
supplemental information.

NOAA WEATHER RADIO BROADCASTS
The NOAA Weather Radio stations listed 
below provide continuous weather broadcasts.  
The reception range is typically 20 to 40 
nautical miles from the antenna site, but can be 
as much as 100 nautical miles for stations at 
high elevations.

Eureka, CA			KEC-82		162.40 MHz WX2
Point Arena, CA			KIH-30		162.55 MHz WX1

CAUTION - SUBMARINE PIPELINES AND CABLES
Additional uncharted submarine pipelines and 
submarine cables may exist within the area of 
this chart.  Not all submarine pipelines and 
submarine cables are required to be buried, and 
those that were originally buried may have 
become exposed.  Mariners should use extreme 
caution when operating vessels in depths of 
water comparable to their draft in areas where 
pipelines and cables may exist, and when 
anchoring, dragging, or trawling.
Covered wells may be marked by lighted or 
unlighted buoys.

CAUTION-RADIOBEACONS
Only marine radiobeacons hyave been calibrated
for surface use.  Limitation on the use 
of certain other radio signals as aids to marine
navigation can be found in the U.S. Coast Guard
Light List and National Geospatial-Intelligence
Agency Publication 117. Radio direction-finder bearings
to commercial broadcasting stations are subject to error
and should be used with caution.
