2Lesson Objectives
- Nature and Navigation of Inland Waters
- Aids To Navigation (ATON)
- River Characteristics
- Waterway Maintenance
- Hazards Challenges
- Locks Locking Through
- Using River Charts
3Types of Inland Waters
- Navigable Waterways
- Roads providing transportation between 2 or
more states or into the sea such as - - Navigable rivers
- Great Lakes
- Intracoastal Waterway
- Non-Navigable Waterways
- Lakes and other waters entirely within one state
4Inland Navigation Rules
- In Force on Navigable Waterways
- Federal equipment requirements apply
- Followed on All Waterways
- Collision avoidance
- Lookouts
- Lighting
- Meeting, crossing overtaking
5Inland ATONs
- US Aids to Navigation System Two Regional
Variations - Western Rivers
- Intracoastal Waterway (ICW)
- Covered in Chapter 5
- Uniform State Waterways Marking System (USWMS)
Now Merged Into USATON System
6Western Rivers ATONS
- River Bank Names Looking Downstream
- Right bank or right descending bank
- Green passing (square) crossing (diamond)
daymarks - Left bank or left descending bank
- Red passing (triangle) crossing (diamond)
daymarks
7Western Rivers ATONS
- Passing Daymarks
- Look like daymarks in Chapter 5
- Mark the side of the river the channel is on
- You continue past the daymark
- Back of the daymark may signal upcoming crossing
daymark
8Western Rivers ATONS
- Crossing Daymarks
- Diamond shaped
- Green or Red (old colors)
- Green white or red white checkerboard (new
colors) - Signal that channel changes banks
- Head for the diamond on the opposite bank
9Western Rivers ATONS
- River Buoys
- Continuously added, removed, or moved
- Do not have letters or numbers
- Not usually shown on river charts
10Western Rivers ATONS
- Mile Markers
- Placards on daymarks or other location
- Distance to mouth of river in statute miles
- Except Ohio River - distance to headwaters
- Help locate position on river chart
11Uniform State Waterways Marking System
- The following slides detail changes to the USWMS
as it merged with the US ATON system. - Following those slides are ones detailing USWMS
pre-merger characteristics of the various aids. - For most boaters these are for historical
reference only
12Uniform State Waterways Marking System
- Effective July 20, 1998, the US Coast Guard
commences a five year phased-in merger of the
Uniform State Waterway Marking System with the
United States Aids to Navigation System. This
merger eliminates distinctions between the two
systems and creates safer, less confusing
waterways.
13Uniform State Waterways Marking System
- Here are the changes that occurred by Dec. 2003.
- USATONS regulatory markers now carry the same
orange bands just above the water line and near
the top as the USWMS system did. - The USWMS black port side channel markers were
replaced with the green markers. - The meaning of a red and white vertically-striped
buoy changes in the USWMS from "do not pass
between the buoy and the nearest shore" to the
USATONS meaning of "safewater all around."
14Uniform State Waterways Marking System
- Continued
- Obstructions currently marked with the USWMS red
and white vertically-striped buoy will be
replaced with either a red or green channel
marker, if practicable, the USATONS black and red
horizontally striped isolated danger marker, or a
newly created USATONS black and white
vertically-striped marker to indicate not to pass
between the marker and the shore. - The USWMS white black-topped markers which mean
"pass to north or east of buoy" and the white
red-topped markers which mean "pass to south or
west of buoy", will be replaced with USATONS red
or green channel markers, the isolated danger
mark, or the new black and white
vertically-striped marker.
15Uniform State Waterways Marking System
- Continued
- USATONS which made no mention of lights on
mooring buoys may now incorporate white lights of
various rhythms. - Ownership identification on private or state aids
to navigation is permitted so long as it does not
change or hinder an understanding of the meaning
of the aid to navigation.
16Uniform State Waterways Marking System
- Three Types of Markers
- Regulatory
- ATONS
- Mooring buoys
17Uniform State Waterways Marking System
- Regulatory Markers - Non-Lateral
- White signs or buoys
- Signs have orange borders
- Buoys have orange band
- Four types
- Boat exclusion
- Danger
- Controlled areas
- Information or directions
18Uniform State Waterways Marking System
19Uniform State Waterways Marking System
- ATONs
- Buoys
- Two types
- Lateral markers
- Non-lateral markers
20Uniform State Waterways Marking System
- Lateral Markers
- Show lateral edges of channel
- Normally occur in pairs
- Solid black or red
- (Black is being replaced by green in many areas)
- Numbered
- May have reflectors or lights
- Red right returning
21Uniform State Waterways Marking System
- Non-Lateral Markers - Cardinal System
- Mark safe passage areas
- Three buoys
- White buoy with red stripes
- Do not pass between buoy and nearest shore
- White buoy with black top
- Pass to north or east
- White buoy with red top
- Pass to south or west
22USWMS ATONs
BLACK RED Usually in pairs Pass between
these buoys (Note black being replaced by green)
PASS TO SPECIFIED DIRECTIONS OF THESE
Do not pass between buoy and nearest shore
Pass to South or West
Pass to North or East
23Non Lateral Marks - Caution
- US Aid - Safe-Water Mark
- Spherical (ball-like) shape
- Indicates navigable water all around
- May be passed on either side
DO NOT CONFUSE THESE ATONS
- USWMS Cardinal Mark
- Do not pass between buoy and closest shore
- This is being changed - for now be careful
24Inland Seamanship
- Challenges include
- Changing water depths
- Speed of currents
- Flash flooding
- Underwater hazards
- Effect of high winds
- Anchoring
- Isolation
25River Currents
- Can be quite strong
- Are concentrated in the channel
- Hinder movement upstream
- Aid movement downstream
- May run in different directions at different
depths - Usually flow around outside of bends
26River Bends
- Outside Bend
- Water is deeper
- Current usually flows faster
- Inside Bend
- Water is shallower shoaling may occur
- Current is slower
- Differences can cause eddies slack water
27Other River Challenges
- Entering a current
- Tows and other traffic
- Debris ice
- Wing dams, dikes, and other devices
- Dredges
- Lowhead High dams
28Maintaining Inland Waters
- Responsibility of U.S. Corps of Engineers
- Techniques include
- Levees
- Revetments
- Dikes or wing dams
- Dredging
29Dredging
- Lights on dredge pipelines
- Dredge lights and shapes
OK to pass this side
Do not pass this side
OK to pass this side
Do not pass this side
Day Shapes

30Lowhead Dams
- Present on many rivers
- Most dangerous for boaters
- Efficient, self-operating drowning machines
- Escape difficult if caught in boil
- Swim under and downstream
- Know where they are and avoid them
31Lowhead Dams
32Lowhead Dams
33Lowhead Dams
34Lowhead Dams
- Same spot, a little to the right
35Lowhead Dams
- Same spot, a little to the left

39High Dams
- Stay Out of Restricted Areas
- Marked by signs, buoys and/or flashing lights
- Upstream - strong undertows
- Downstream - tailrace
- Boils backwash
- Dam Gates
- Wicket v. Tainter
40Locks
- Operation
- Priorities for Use
- Commercial Traffic
- Hazardous Cargo
- Communications
41Lock Operation
42Lock Operation
43Lock Operation
- Upstream lock door RISES from floor
44Lock Operation
- Downstream doors swing or lift
- Watch for air BLAST as it opens
45Locking Through
- Do Not Enter Without Appropriate Signal
- Green light or prolonged blast
- Follow Commands of Lockmaster
- No Wake!
- Wear PFD
- Tie-Up to Appropriate Fitting
- Tend Lines Carefully
46River Charts
- Sources
- NOAA (some)
- U.S. Corp of Engineers (most)
- Characteristics
- NOAA - essentially the same as coastal charts
47River Charts
- Characteristics - Non-NOAA Charts
- Many show limited information
- Principal geographic features
- Channel sailing line
- Fixed ATONs
- Mile markers
- Navigation lights sometimes shown
- Water depths and buoys rarely shown
48River Charts
- Study River Charts Beforehand
- Symbols may be different than those on coastal
charts - North is rarely up
- Note downstream direction
49Non NOAA River Chart
50NOAA River Chart
Portion of NOAA Chart 12375 - CT River
51Commercial Traffic
- Ocean-Going v. River Tows
- Beware Ocean-going tows can be found on many
rivers, especially near the mouth - Watch Out For The Tow
- Keep clear
- Prop wash
- Blind spot
- VHF Communication
