There is a better launch at Priest Rapids Dam and then you can run down river to the holes described earlier.There is also a paved launch at mile marker 63 on the hi-way between Vernita and Othello.Lots of good fishing at both places and your inboards fine.Watch your depth and take it slow in unfamiliar waters.Get behind another prop boat and follow him.Yes,the evening bite can be terrific.Start fishing about 3pm to dark.
Good luck,lester
