i've never been able to figure out how to get below the 522 bridge from the bank. i can tell you all one thing for sure...floating a driftboat from lewis street downstream is NOT a good idea. the nearest takeout is downtown snohomish, which requires a lot of rowing.
it sounded like a good idea, alright? we had nothing better to do.
i'd suggest parking at lewis street bridge in monroe and walking downstream a ways. maybe a long ways. you'll find fish

any of that water around the prison is good.
