Although most people think of water supply and availability as a western problem, that matter is not unique to the West.
David Soll discusses an eastern situation in Empire of Water: An Environmental and Political History of the New York City Water Supply. A useful collection of articles written by water specialists about the water problem in the West is Water in the 21st-Century West: A High Country News Reader, edited by Char Miller.
Rivers are also an important aspect of environmental history, and some rivers even have their own biographies. Ellen Wohl covers two in Wide Rivers Crossed: The South Platte and the Illinois of the American Prairie. Jeff Crane discusses the Elwha River in Washington State. The Elwha has recently been in the news because of the destruction of its dams, as Crane explains in Finding the River: An Environmental History of the Elwha.
