The Big Blue River.

The Big Blue River is a tributary of the Kansas River. It discharges its waters into a reservoir called Tuttle Creek Lake which lies slightly northeast of Manhattan, Kansas. The lake is manmade, held back by a manmade dam composed of the limestone, silt, and gypsum dredged out of the floodplain by bulldozers left to rust underneath the flooded area. It is a state park area, although the flood of 1993 decimated much of the northern area.
