Types of Navigation Problems

Includes areas requiring additional, upgraded, or relocated buoys, beacons and ranges for safe channel alignment.

Those which impair the night vision of a pilot, or those which obscure or block the lights on aids to navigation or navigation lights on other vessels.

Include bridges located in bends or crosscurrent areas. Also includes bridges with narrow or misaligned spans. May indicate inadequate fender systems which are too low, weak, or incompatible with basic tow maneuvering. May also indicate inadequate navigation lights or aids to navigation which make span alignment difficult for pilots.

Hardened sites are created for shoreline erosion protection, and to protect submerged pipeline and cable crossings. These sites can cause barge damage when scrap steel or large, angular concrete debris or rocks are used.

Moorings provide a safe "tripping" area for vessels faced by inclement weather or other delays. They are necessary on both sides of all locks. They have been installed in many areas, and are scheduled for installation in several more.

Some deep draft channels are not marked as wide as possible for safe passage of shallow draft vessels.

Barges, boats, and other vessels, which when located adjacent to near navigation channels, pose a danger to passing barges.
