The history of the Rio Grande since the late nineteenth century reflects the evolution of water-resource management in the West. It was here that the earliest interstate and international water-allocation problems pitted irrigators in southern New Mexico against farmers downstream in El Paso and Juarez, with the voluntary resolution of that conflict setting important precedents for national and international water law.

In this first scholarly treatment of the politics of water law along the Rio Grande, Douglas R. Littlefield describes those early interstate and international water- apportionment conflicts and explains how they relate to the development of western water law and policy and to international relations with Mexico. Littlefield embraces environmental, legal, and social history to offer clear analyses of appropriation and riparian water rights doctrines, along with lucid accounts of court cases and laws. Examining events that led up to the 1904 settlement among U.S. and Mexican communities and the formation of the Rio Grande Compact in 1938, Littlefield describes how communities grappled over water issues as much with one another as with governmental authorities.

"Conflict on the Rio Grande" reveals the transformation of nineteenth- and early twentieth-century law, traces changing attitudes about the role of government, and examines the ways these changes affected the use and eventual protection of natural resources. Rio Grande water policy, Littlefield shows, represents federalism at work--and shows the West, in one locale at least, coming to grips with its unique problems through negotiation and compromise.

When Europeans first arrived at what is now California's San Joaquin Valley, they found a vast landscape of wetlands, small ponds, riparian forests, and grasslands surrounding three large swampland lakes. What greets a visitor to the region today is a dramatically different view of mile after mile of row crops, vineyards, orchards, and grazing acreage - some of the most fertile and productive agricultural land in the world. This remarkable transformation, with its enduring consequences, is at the center of Ruling the Waters, a legal, social, and environmental history of how western water law shaped, and was shaped by, the subjugation of the largest freshwater wetlands wildlife habitat in the West. At the heart of efforts to wrest arable land from the region was the Kern River, which rises in the Sierra Nevada and carries snowmelt to what was once a great network of lakes, sloughs, and marshes at the southern end of California's Central Valley. In Ruling the Waters Douglas R. Littlefield describes how, over the course of the nineteenth and early twentieth centuries, pioneers and entrepreneurs diverted water out of this network of waterways to extract gold in the mountains and irrigate farms lower down the river, and how the law was made to accommodate these practices. Struggles over the Kern River's water established one of the most important concepts in water law in some parts of the United States - that prior appropriation, dependent on the chronological order of diversions from waterways, could legally coexist with riparian rights, which restrict water usage to landownership directly next to a river or stream. Littlefield traces this concept to the 1886 California Supreme Court case of Lux v. Haggin - which pitted the giant farming and cattle company of Miller & Lux against a prominent land baron, James B. Haggin - and shows how the lawsuit profoundly shaped future waters issues, which in turn influenced water laws in other western states that were grappling with similar questions. Far from a dry legal history, Ruling the Waters tells a story with world-wide historical environmental ramifications, a tale of competing personalities and values and visions that forever changed both the economy and the ecology of the American West.
