With the system of dams on the Columbia and Snake Rivers, we have
over 400 miles of navigable inland waterway available for transporting
cargo the most environmentally friendly and efficient way possible.
If barge navigation were halted, it  would
take an additional 120,000 rail cars or more than 700,000 semi-trucks
annually to haul the cargo currently being carried via barge. Not
only does barge transportation require a great deal less fuel than
rail or truck to haul the same amount of cargo, it also results in
significantly lower emissions being released into the environment. |

 The Kathryn B, pictured at left, is pushing 5 barges carrying 5,000 BDU's of wood chips. That's equivalent to over 100 rail cars or over 350 semi-trucks. |
