NOTES:

NOTE A 
Navigation regulations are published in Chapter 2, U.S. Coast Pilot 10. 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, 14th Coast Guard District in Honolulu, Hawaii or at the Office of the District Engineer, Corps of Engineers in Honolulu, Hawaii.
Refer to Code of Federal Regulations section numbers.


SYMBOLS AND ABBREVIATIONS 
For Symbols and Abbreviations see Chart no. 1.


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


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


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


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 10 for important supplemental information.


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.


CAUTION 
Improved channels are subject to shoaling, particularly at the edges.


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


STORM WARNINGS 
The National Weather Service displays storm warnings at the following approximate locations:
Kailua-Kona, Kona Inn (1938.6' - 15600.0')
Mahukona (2011.2' - 15554.2')


NOAA WEATHER RADIO BROADCASTS 
The NOAA Weather Radio stations 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.
Kulani Cone, HI		KBA-99		162.55 MHz
South Point, HI		KBA-99		162.55 MHz
Mt Haleakala, HI	KBA-99		162.40 MHz


SUBMARINE PIPELINES AND CABLES 
Additional uncharted submarine pipelines and submarine cables may exist within the area. 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 exists, and when anchoring, dragging, or trawling. Covered wells may be marked by lighted or unlighted buoys.

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.
