Smallmouth like cool, clear streams with moderate current, as well as large, clear lakes. Preferred habit has a gravel or rubble substrate, boulders, some shade and cover, along with deep pools for stream environments. Smallmouth bass are widespread despite not being native to Maryland waters. They were first introduced in 1834 when a B&O Railroad employee transported approximately 20 fish from the Wheeling River in West Virginia to the C&O Canal Basin in Cumberland, Maryland. Today they are found throughout the non-tidal Potomac and Susquehanna river watersheds and are common in most of our larger freshwater impoundments.
