AIDS TO NAVIGATION
Buoys marking a narrow or dredged channel are normally established on the edge of the channel.  Light structures established to mark the main channel may be located in shoal water some distance back of the channel edge.
Not all the aids to navigation are shown on this chart.  For details of inner waters, the larger scale charts must be consulted. 

ANCHORAGE
Vessels anchoring in Lake Erie should do so with caution after noting the underwater positions of all gas wells, pipelines, cables and other installations.  For information concerning Anchorage Areas, refer to No. 21 of the Annual Notices to Mariners.  Recommended anchorage areas are shown in the file.

CABLES
The symbols for submarine and overhead cables do not differentiate between cables conducting electric power, often at high voltages, and other types of utility cables.  Mariners are advised to exercise caution when passing under all overhead cables and to avoid anchoring or conducting seabed operations in the vicinity of submarine cables.  The clearance of an overhead cable may differ from its charted value due to changes in atmospheric conditions, water levels and other factors.  For additional information, consult Notice No.16 in the Notices to Mariners, Annual Edition and the appropriate volume of CHS Sailing Directions.

COURSE
The recommended courses have been adopted by the Lake Carriers' Association (U.S.A) and the Chamber of Marine Commerce (Canada).

DRILLING TOWERS
Mariners are advised that oil and gas drilling towers are temporarily established in various parts of Lake Erie. These towers exhibit a quick-flashing white light and are equipped with an automatic fog signal, sounding one blast of 2 seconds duration followed by 18 seconds silence.

GAS PIPELINES and WELLHEADS
High pressure Natural Gas pipelines lie on the lake bottom with wellheads standing 1.5 metres above the lakebed.  Damage to these installations can result in an extremely dangerous situation.  Gas well activities are continuous and as a result, the newest installations may not be shown or may vary between nautical chart editions.

ST. LAWRENCE SEAWAY VESSEL TRAFFIC CONTROL SYSTEM
For information regarding lock data, limiting vessel dimensions, and regulations governing the transit of vessels in the St. Lawrence Seaway between the Port de Montral and Lake Erie, refer to the Seaway Handbook of which a current copy must be carried on board all vessels transiting the Seaway.  A copy of the Seaway Handbook can be obtained from the Information Office, St. Lawrence Seaway Authourity, Ottawa.

VESSEL TRAFFIC SERVICES
Canadian waters of Lake Erie and Lake Huron Traffic services calling-in-point; arrow indicates direction of vessel movement.  Mandatory calling-in-points are identified numerically.  Voluntary calling-in-points are identified alphabetically. For additional information concerning these services, see Radio Aids to Navigation, Central and Arctic Region, Part3.

96 HOURS NOTIFICATION PRIOR TO ENTERING CANADIAN WATERS
Effective October 11, 2001, 0000 UTC, all vessels that are:
- of 500 tons gross tonnage or more;
