Canadian Hydrographic Service Central and Arctic Region CAEA3010 - WELLAND CANAL INDEX AIDS TO NAVIGATION CABLES MANUAL FOG SIGNALS RADAR REFLECTORS ST. LAWRENCE SEAWAY CANAL ILLUMINATION< 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. INDEX CABLES For the mariners safety, all submarine and overhead cables are assumed to conduct electric power at high voltages and contact with or proximity to these poses an extreme danger. 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. However if anchors become hooked onto a cable care must be taken not to sever the cable. Cables installed since the date of publication of this cell may not be charted. Sufficient clearance must be allowed under all overhead cables. Actual clearances may differ from charted values due to changes in atmospheric conditions, ice buildup and/or water levels. For additional information, consult Notice to Mariners No. 16 of each year and the appropriate volume of CHS Sailing Directions. INDEX MANUAL FOG SIGNALS Mariners requiring horn to be turned on can activate it by clicking radio mike five times within 5 seconds on channel 19VHF (156.95MHz). Horn can be activated with 1 watt power at 3 NM range. Horn will stay activated for 30 minutes and can be reactivated as required. INDEX RADAR REFLECTORS Most of the major lighted buoys are equipped with radar reflectors. Individual radar reflectors have not been charted. INDEX ST. LAWRENCE SEAWAY For information regarding lock data, limiting vessel dimensions and regulations governing the transit of vessels in the St. Lawrence Seaway between the Port of Montréal and Lake Erie, refer to the Seaway Handbook of which a current copy must be carried on board all vessels transiting the Seaway.
