Big River offers you opportunities to catch a wide variety of fish, from catfish and crappie to large and smallmouth bass. The portion of the Big River that extends from the Hwy. 21 bridge to the Meramec River has been designated by the Missouri Department of Conservation as a Smallmouth Bass Special Management Area. Special regulations of length and possession limits apply to smallmouth bass in this area. Regulations are posted at the boat launch and gravel bar in the Big River Day-Use Area.
