I'm looking into the prospects of going up the Columbia River and into Lake
Celilo/Umatille.

I see there is a dam with locks at about the Dalles but don't know it there
are any other navigation considerations along the way.

I have a 38' Ingrid sail boat that draws 6' and mast clearance of 54'.

I know I will have to motor most of the way and can handle several knot of
current for brief period. Just what is the river current in some of the
narrow passages.

(To tell the truth, I always though crossing the bar and the enterance of
the Columbia was the major hurtle.)

Commnents and recommendations appreciated.
