All the rigs mentioned are good for that river! I grew up on the east side of michigan but as anyone in the surrounding states knows the manistee is the place to be for steelies. I would suggest popping into a little shop called fishermans headquarters on cabrafae highway. The guys in there grew up on the river and its family owned and operated as for how to fish it for spring steelies, go with a light bobber and jig head with o god i am giving the secret away... Wax worms. They seem to work best. I just recently moved away to arizona so i could not tell you the color jig head to use but believe me it means the world to your success to find out what they are on this year. Also if it gets really slow, go up to the dam and float minnows and you might get a suprise or two. Browns, Eyes and the occasional spring salmon.
