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 Notices to Mariners. Information concerning the regulations may be obtained at the Office of the Commander, 8th Coast Guard District in New Orleans, LA, or at the Office of the District Engineer, Corps of Engineers in Mobile, AL. Refer to charted regulation section numbers.
|
|
|
|
|
|
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).
|
|

|
|
AIDS TO NAVIGATION
|
|
Consult U.S. Coast Guard Light List for supplemental information concerning aids to navigation.
|
|
|
|
|
|
SUPPLEMENTAL INFORMATION
|
|
Consult U.S. Coast Pilot 5 for important supplemental information.
|
|
|
|
|
|
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.
|
|
|
|
|
|
CAUTION - TEMPORARY CHANGES
|
|
Temporary changes or defects in aids to navigation are not indicated. See Local Notice to Mariners.
|
|
|
|
|
|
NOAA WEATHER RADIO BROADCASTS
|
|
The NOAA Weather Radio station 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.

|
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.
|
|
|
|
|
|
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.

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

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 - 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/ .
|
|
|
|
|
|
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.
