Where are tide times for the Columbia posted? More specifically what are the adjustments or delays for upriver locations from the posted Astoria times. If it is high tide at Astoria at noon what time is it high at Multnomah Channel or is it the same?
I just buy a book or two or three at Fisherman's. That way you have one everywhere just in case the opportunity presents itself and you want to check. BTW, did anybody else go fishing on 3/10/04 and think the tide seemed slow.
