NOTES:
|
|
|
|
NOTE A
|
|
Navigation regulations are published in Chapter 2, U.S. Coast Pilot 5. 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, 7th Coast Guard District in Miami, FL, or at the Office of the District Engineer, Corps of Engineers, in Jacksonville, FL. Refer to charted regulation section numbers.

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

|
|
Largo, FL KEC-38 162.450 MHz

|
SUPPLEMENTAL INFORMATION
|
|
Consult U.S. Coast Pilot 5 for important supplemental information.
|
|
|
|
|
|
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 - TEMPORARY CHANGES
|
|
Temporary changes or defects in aids to navigation are not indicated. See Local Notice to Mariners.
|
|
|
|
|
|
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.
|
|
|
|
|
|
HURRICANES AND TROPICAL STORMS
|
|
Hurricanes, tropical storms and other major storms may cause considerable damage to marine structures, aids to navigation and moored vessels, resulting in submerged debris in unknown locations. Charted soundings, channel depths and shoreline may not reflect actual conditions following these storms. Fixed aids to navigation may have been damaged or destroyed. Buoys may have been moved from their charted positions, damaged, sunk, extinguished or otherwise made inoperative. Mariners should not rely upon the position or operation of an aid to navigation. Wrecks and submerged obstructions may have been displaced from charted locations. Pipelines may have become uncovered or moved. Mariners are urged to exercise extreme caution and are requested to report aids to navigation discrepancies and hazards to navigation to the nearest United States Coast Guard unit.
|
|
|
|
|
|
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.
|
|
|
|
|
|
INTRACOASTAL WATERWAY AIDS
|
|
The U.S. Aids to Navigation System is designed for use with nautical charts, and the exact meaning of an aid to navigation may not be clear unless the appropriate chart is consulted. Aids to navigation marking the Intracoastal Waterway exhibit unique yellow symbols to distinguish them from aids marking other waterways. When following the Intracoastal Waterway westward from Carrabelle, FL, to Brownsville, TX, aids with yellow triangles should be kept on the starboard side of the vessel and aids with yellow squares should be kept on the port side of the vessel. A horizontal yellow band provides no lateral information, but simply identifies aids to navigation as marking the Intracoastal Waterway.
|
|
|
|
|
|
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 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.

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 .

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 (Quality of Data) 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 - USACE HYDROGRAPHIC SURVEYS
|
|
USACE conducts hydrographic surveys to monitor navigation conditions. These surveys are not intended to detect underwater features. Undetected features hazardous to surface navigation may exist in federal channels, as might shoaling, particularly along the edges of channels. For more information, visit https://navigation.usace.army.mil/Survey/Hydro/ .
