The Huzzah conservation area has good wading access on the Meramec,Coutois, and the Huzzah. Look for slower deep pools. Sometimes it seems like, when wading around gar, they want let you know they are around. Smacking the water, sipping air on the surface, and always following my cranks but never a hook up. Also, the big river and bourbouse are other good options fairly close to St. Louis.
