NOAA CUSTOM CHART

NOTES GEOSPATIAL DATABASE

VERSION 3.0B - 20 FEBRUARY 2025

The records of the NOAA Custom

Chart Notes Geospatial Database are

current as of February 20, 2025.

Subsequent additions and refinements

are to be expected. Please refer to

all

available

navigational

publications for complete information

about the charted area.

CAUTION

AUTOMATED CHART GENERATION

This NOAA Custom Chart has been

automatically

rendered

from

NOAA

Electronic Navigational Chart (NOAA

ENC®) data. Mariners using this NOAA

Custom Chart are advised that this is

a static reproduction of the NOAA

ENC®. This NOAA Custom Chart has not

been individually quality checked or

adjusted

for

optimal

use

for

navigation. The portrayal may be at a

different scale from that of the

original NOAA ENC®. Mariners are

advised to use caution when using

this NOAA Custom Chart for navigation

and are encouraged to use the latest

NOAA ENC® to access the most up-to-

date information. Mariners must also

comply with all applicable regulatory

requirements.

CAUTION

CHART UPDATES

This NOAA Custom Chart contains up-

to-date information only as of the

time of creation, and will become

outdated. Mariners are advised to

visit

https://

distribution.charts.noaa.gov/

navigation-updates/

to

check

for

critical and routine updates, and to

render a new NOAA Custom Chart when

the ENC data used to make the chart

is updated. Notices to Mariners are

not issued for corrections to this

NOAA Custom Chart.

HEIGHTS

Heights of fixed aids to navigation

and vertical clearances of overhead

obstructions will be shown in feet if

the units are set to feet or fathoms.

If units are set to meters, heights

will

be

shown

in

meters.

Land

elevation values are shown in meters

only.

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.

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.

WARNING

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.

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.

MINERAL DEVELOPMENT STRUCTURES

Obstruction lights and sound (fog)

signals

are

required

for

fixed

mineral

development

structures,

subject to approval by the District

Commander, U.S. Coast Guard (33 CFR

67).

VESSEL TRAFFIC SERVICES (VTS)

The U.S. Coast Guard operates a

mandatory

Vessel

Traffic

Services

(VTS)

system

in

the

Hudson,

Galveston, and Texas City waterways.

Vessel

operating

procedures

and

designated radiotelephone frequencies

are published in 33 CFR 161, the U.S

Coast Pilot, and/or the VTS User’s

Manual. Mariners should consult these

sources for applicable rules and

reporting

requirements.

Although

mandatory

VTS

participation

is

limited to the navigable waters of

the United States, certain vessels

are encouraged or may be required, as

a condition of port entry, to report

beyond

this

area

to

facilitate

advance

vessel

traffic

management

within the VTS area.

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

Temporary changes or defects in

aids to navigation are not indicated

on this chart. See Local Notice to

Mariners.

CAUTION

LIMITATIONS ON THE

USE OF RADIO SIGNALS

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

BASCULE BRIDGES

For bascule bridges, whose spans do

not open to a full upright or

vertical position, unlimited vertical

clearance is not available for the

entire charted horizontal clearance.

CAUTION

SUBMERGED CABLES AND PIPELINES

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

Open bascule overhangs Galveston

Channel.

HOUSTON SHIP CHANNEL

Large

vessels

traversing

the

Houston Ship Channel can cause swells

engulfing the shoals alongside the

channel.

Small

craft

should

use

extreme caution when operating in

these areas.

CAUTION

Stakes, piles and platforms, some

submerged, may exist between charted

piling

and

platforms

along

the

maintained

channels.

Piles

and

platforms are not shown where they

interfere with a light symbol.

CAUTION

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

Hydro.

CAUTION

Improved channels are subject to

shoaling, particularly at the edges.

OBSTRUCTIONS

Numerous stakes may exist between

piling and platforms along Houston

Ship Channel. Pilings, platforms, and

stakes may be submerged.

MOORING BUOYS

Mooring buoys are located north of

the

Galveston-Freeport

Cutoff

Channel.

NOAA WEATHER RADIO BROADCASTS

The NOAA Weather Radio station

listed

below

provides

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.
