Unraveling a complex web of tension, distrust, and political maneuvering, Damming the Gila continues the story of the Gila River Indian Community’s struggle for the restoration of its water rights. This volume chronicles the history of water rights and activities on the Gila River Indian Reservation. Centered on the San Carlos Irrigation Project and Coolidge Dam, it details the history and development of the project, including the Gila Decree and the Winters Doctrine. Embedded in the narrative is the underlying tension between tribal growers on the Gila River Indian Reservation and upstream users. Told in seven chapters, the story underscores the idea that the Gila River Indian Community believed the San Carlos Irrigation Project was first and foremost for their benefit and how the project and the Gila Decree fell short of restoring their water and agricultural economy.

Our rivers are in crisis and the need for river restoration has never been more urgent. Water security and biodiversity indices for all of the world’s major rivers have declined due to pollution, diversions, impoundments, fragmented flows, introduced and invasive species, and many other abuses. Developing successful restoration responses are essential. Renewing Our Rivers addresses this need head on with examples of how to design and implement stream-corridor restoration projects. Based on the experiences of seasoned professionals, Renewing Our Rivers provides stream restoration practitioners the main steps to develop successful and viable stream restoration projects that last. Ecologists, geomorphologists, and hydrologists from dryland regions of Australia, Mexico, and the United States share case studies and key lessons learned for successful restoration and renewal of our most vital resource.

In the late nineteenth and early twentieth centuries, Americans assumed the land and water resources of the West were endless. Water was as vital to newcomers to Arizona’s Florence and Casa Grande valleys as it had always been to the Pima Indians, who had been successfully growing crops along the Gila River for generations when the white settlers moved in. Diverting the Gila explores the complex web of tension, distrust, and political maneuvering to divide and divert the scarce waters of the Gila River. Residents of Florence, Casa Grande, and the Pima Reservation fought for vital access to water rights. Into this political foray stepped Arizona’s freshman congressman Carl Hayden, who not only united the farming communities but also used Pima water deprivation to the advantage of Florence-Casa Grande and Upper Gila Valley growers. The result was the federal Florence-Casa Grande Project that, as legislated, was intended to benefit Pima growers on the Gila River Indian Reservation first and foremost. As was often the case in the West, well-heeled, nontribal political interests manipulated the laws at the expense of the Indigenous community.

No fewer than forty million people have come to rely on the Colorado River system in modern times—a river system immersed in an unprecedented, unrelenting megadrought for more than two decades. Attempting to navigate this “new normal,” policymakers are in the midst of negotiating new management rules for the river system, a process coinciding with the compact’s centennial that must be completed by 2026. Animated by this remarkable confluence of events, Cornerstone at the Confluence leverages the centennial year to reflect on the compact and broader “Law of the River” to envision the future. It is a volume inviting dialogue about how the Colorado River system’s flows should be apportioned given climate change, what should be done about environmental issues such as ecosystem restoration and biodiversity protection, and how long-standing issues of water justice facing Native American communities should be addressed.
