Starting life in the Rocky Mountains of Montana, the river cuts through the Great Plains before emptying into the Mississippi River. It used to flood so often and wash away so much soil that it was nicknamed "Big Muddy." Once dams had tamed the river's power, the farms and cities along its banks began to benefit from irrigation water and inexpensive electricity. Book jacket.
