I've got a book called "Fly Fishing for Trout in Missouri", by Chuck Tryon. Pretty appropriate, huh? *
It does list Mill Creek, in Phelps county. Interstate 44 west to exit 179 south through Newburg. Right on Hwy P. 3 miles to Mill Creek recreation area. You might wanna pick up the book at Feather-Craft. It's nice just to read about the streams, *8-) even if you don't make it to all of them.
