The Lock

The lock at Bonneville are one of 7 on the Columbia/Snake River navigation channel.  Each on is large enough to accommodate 5 barges at the same time.  River traffic is an important part of the mission of the Bonneville Lock and Dam.  Over 50% of wheat produced for export in the US is shipped on barges coming down the river.

 Here is a barge entering the lock at 9pm last night.














But other vessels also use the lock.  This morning this river cruise ship passed through.  The ship moored at Stevenson, Wa. and the passengers were bussed to the dam for a visit.
Private pleasure boats are able to take advantage of the lock as well for free.
