Columbia River
RM 0 to 309 (Oregon-Washington border)
Can someone tell me how to properly chart the designation "RM 0 to 309"?
My thanks in advance!
RM = River Miles
RM 0 = Mouth of river
RM 309 = 309 miles frm the mouth
on a water way where you can use a boat all you have to do to legally camp is be outside the commercial shipping lanes... all other waters is fair game.
