It is widely distributed in the Mississippi River and its large tributaries. Bigmouth buffalo live in lowland lakes, sloughs, and big rivers with slow to still waters and bottoms of mud, silt, sand, and gravel. They are especially abundant in flood plain and oxbow lakes.
Bigmouth buffalo spawn in April or May, depending on how far north the population is. Adults migrate into the shallow bays and inlets of lakes or into sloughs and flooded marshes of large rivers.
