NOTES:

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 the District Engineer, Corps of Engineers in Los Angeles, California. Refer to charted regulation section numbers.


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).


CAUTION - USE OF RADIO SIGNALS (LIMITATIONS)
Limitations on the use of radio signals as aids to marine navigation can be found in the U.S. Coast Guard Light Lists 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.


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


CAUTION - TEMPORARY CHANGES
Temporary changes or defects in aids to navigation are not indicated. See Local Notice to Mariners.


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.


ADDITIONAL INFORMATION
Additional information can be obtained at www.nauticalcharts.noaa.gov.


AUTHORITIES
Hydrographic and topography by the National Ocean Service, Coast Survey, with additional data from the Corps of Engineers, and U.S. Coast Guard.


ADMINISTRATION AREA
The entire extent of this ENC cell falls within the limits of an Administration Area. This area covers land, internal waters, and territorial sea. The territorial sea is a maritime zone which the United States exercises sovereignty extending to the airspace as well as to its bed and subsoil. For more information, please refer to the Coast Pilot.


CAUTION - QUALITY OF BATHYMETRIC DATA
The areas represented by the object M_QUAL (Quality of Data) are approximate due to generalizing for clarity. Caution is advised, particularly for nearshore navigation or voyage planning. M-QUAL represents areas of uniform quality of bathymetric data. The CATZOC (Category of Zone of Confidence in Data) attribute of M_QUAL provides an assessment of the overall zone of confidence.


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.


LOCAL MAGNETIC DISTURBANCE
Differences of as much as 5 from the normal variation have been observed up to 3 miles off the south and southeast coast of San Clemente Island.


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.

Santa Ana, CA		        WWG-21		162.450 MHz


CAUTION - SUBMERGED SUBMARINE OPERATIONS
Submerged submarine operations are conducted at various times in the waters contained on this cell. Proceed with caution.


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.


WARNING - NAVAL RESERVATION
San Clemente Island is a NAVAL RESERVATION. All vessels are warned that the vicinity of the island is dangerous on account of gunfire and bombing.


WATER LEVELS, CURRENTS, AND TIDES
Real-time water levels, tide predictions, and tidal current predictions are available on the internet from NOAA's Center for Operational Oceanographic Products and Services (CO-OPS) at https://tidesandcurrents.noaa.gov/water_level_info.html and https://tidesandcurrents.noaa.gov/currents_info.html.


WEST COAST OFFSHORE VESSEL TRAFFIC
Vessels 300 gross tons or larger transiting along the coast anywhere between Cook Inlet and San Diego should voluntarily stay a minimum of 25 nautical miles offshore. See U.S. Coast Pilot 7, Chapter 3 for details.
