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 Notices 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.


AUTHORITIES
Hydrography and Topography by the National Ocean Service, Coast Survey, with additional data from the Corps of Engineers, Geological Survey, U.S. Coast Guard, and National Geospatial-Intelligence Agency.


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


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.


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).


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.
 

CAUTION - DREDGED AREAS
Improved channels are subject to shoaling, particularly at the edges


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.


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.


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.

San Diego, CA	KEC-62	162.400 MHz


CABLE AND PIPELINE AREAS  
The cable and pipeline areas falling within the areas of the larger scale charts are shown thereon and are not repeated.


NOTE D
Submerged submarine operations are conducted at various times in the waters contained on this chart. Proceed with caution.


VESSEL TRANSITING
The U.S. Coast Guard and the Pacific States/British Columbia Oil Spill Task Force endorse a system of voluntary measures and minimum distances from shore for certain commercial vessels transiting along the coast anywhere between Cook Inlet, Alaska and San Diego, California. See U.S. Coast Pilot 7, Chapter 7 details.


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.


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


USACE HYDROGRAPHIC SURVEYS
USACE conducts hydrographic surveys to monitor navigation conditions. These surveys are not intended to detect underwater features. Uncharted features hazardous to surface navigation are not expected but may exist in federal channels. For more information visit https://navigation.usace.army.mil/Survey/Hydro/ .
