Fall River Perch Locations

[dudewheresmyboat]

Looking for tips from the Pro's of where I can find perch on a river system (stcroix, mississippi).  I know of a few areas soft bottom next to rock, no current with laydowns, backwaters but Ive been able to catch bluegill and the occasional crappie there, what should I be looking for and where should I be looking?  The main channel is atleast a few hundred yards of where I normally fish, any tips and ideas would be appreciated. Thanks.

Killed the yeller bellies up here last weekend. Found a rocky river bank that dropped to about 8 feet. Caught them on minnows at the bottom of the drop.

Look for the rocky river bank on the St. Croix-what bank isn't?
