they do catch sturgoen in the snohomish all the way upto hwy2. the better fishing(according to local guides) is ebey and steamboat sloughs. you can access ebey near the mill in marysville(under i-5) and steamboat from the snohomish just upstream od i-5. sturgoen have been caught in ebey all the way up to hwy2. if you have a sled the better fishing is hat slough(stillaguamish). i used to clean that access area and talked to a lot of folks with fish. it aint the columbia but its fishin! good luck and fish on!
