Hey, learned a new thing today. There are towing lanes defined for barge traffic from Washington down to San Fran. This is a cooperative effort between the crabbers and the barge guys so they aren't getting tangled up. I've seen car carriers using them as well.
Anyways, here's an online copy of the 2005 charts:

It changes annually or even more often so use at your own peril. I am getting the newer info sent to me. I will figure out how to get it to ya'll when it arrives so that we don't overwhelm the office.
WSU extension is coordinating it. OSU used to do it and stopped back in the 90's.
