There are roughly 135 recorded species of fish in the U.S. State of Kansas.
The following tags note species in each of those categories: Kansas is located in the Great Plains region which is characterized by mostly slow-running rivers and a near total absence of large naturally occurring lakes excluding oxbows and a few shallow salt marshes and sloughs.
Since the European settlement of the area, many rivers and creeks have been dammed creating large reservoirs, largely by the United States Army Corps of Engineers and the Bureau of Reclamation.
The biggest of these reservoirs is Milford Lake at 15,709 acres (6,357 ha).
Kansas is home to 12 rivers basins, all of which drain into the Gulf of Mexico approximately 507 miles (816 km) south.
