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 Sacramento, 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, and U.S. Coast Guard.


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


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


CAUTION - 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 station listed below provide continuous weather broadcasts. The reception range is typically 37 to 74 kilometers / 20 to 40 nautical miles from the antenna site, but can be as much as 185 kilometers / 100 nautical miles for stations at high elevations. 

Eureka, CA	KEC-82		162.400 MHz WX2


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.


ADMINISTRATION AREA
This area covers land, internal waters and territorial sea. The territorial sea is a maritime zone over 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.


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


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.


COMMENTS REQUESTED
NOAA encourages users to submit inquiries, discrepancies, or comments about this chart via NOAA's ASSIST tool at https://www.nauticalcharts.noaa.gov/customer-service/assist/.


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.


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.
