at the bottom of carwash hill theres a pump station, its really deep and i used to slay the smallies all night on rattle traps there. also some cats roam the area so set out a crawdad or some crawlers. its rocky so be careful. also further up is some calm water and you can have a lot of fun with an UL and 4lb with some small worm hooks and earth worms.
check out the springs for trout and sculpin. i pulled a 13" sculpin out of there and some trout to 3lbs.
have fun in fort leonard wood.
