Sappah

Sappah, a Dakota name meaning “black,” was used for the Black River of western Wisconsin. The river rises in the inland country and flows southwest toward the Mississippi, gathering streams from forests and wetlands along its course. Near its mouth it spreads into channels and backwaters beside the great river. The name of the river recalls the dark water that runs through a broad watershed between the Wisconsin and Chippewa rivers.
