ANCHORAGE AREA
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.

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.
