Wolf Creek National Fish Hatchery is administered by the U.S. Fish & Wildlife Service and is supported by your Federal tax dollars. Fish raised on Federal hatcheries are stocked in public waters to support Federal fishery responsibilities mandated by law. These include fish for mitigation where, for example, man-made dams have altered a stream’s natural reproductive capability; to recover threatened or endangered populations; to restore interjurisdictional fish populations, or to support depleted recreational fish populations in Federal and state waters.
