John O. Anfinson
Univ Of Minnesota Press
The River We Have Wrought is a landmark history of the upper Mississippi, from early European exploration through the completion of a navigable channel and a system of locks and dams in the mid-twentieth century.  John Anfinson examines how politics has shaped the landscapes of the Upper Midwest and how taming the Mississippi River has affected economic sustainability, river ecology, and biological diversity.
