Colorado River Water

The Arizona Water Banking Authority (AWBA) was established in 1996 to make full use of Arizona’s Colorado River entitlement. It aims to address groundwater depletion in central Arizona and to protect Colorado River water users against future shortages due to interannual variability in water availability. Each year, the AWBA pays the costs to deliver any of the state’s unused entitlement to Colorado River water into central and southern Arizona and to store that water underground. The AWBA stores water on behalf of Central Arizona Project municipal subcontractors, other mainstream municipal Colorado River water rights holders, and tribal entities. Through its interstate banking agreements, the AWBA can also store water on behalf of the states of Nevada and California. Water stored by the AWBA is accounted for using Arizona’s statutorily created system of long-term storage credits (LTSCs), which allow future pumping of stored water within the same hydrologic basin. During shortage conditions in the Lower Basin of the Colorado River, the AWBA will distribute the LTSCs, enabling recipients to pump groundwater that otherwise would not be permitted. In this way, the AWBA serves as a unique insurance mechanism against shortages for users of Colorado River water in Arizona and the Lower Basin. To date, the AWBA’s focus has been on storage, yet in the coming years, its activities will shift to recovery, and it will need to confront additional challenges associated with matching supplies with demands and limitations on water available for recharge.

Colorado River Water

After examining one of the world’s worst case scenarios, the book turns to the state of Arizona that has one of the world’s more progressive groundwater management programs. After years of debate, the federal government eventually agreed to finance the Central Arizona Project to bring Colorado River water to central Arizona, but with a catch—Arizona first had to get their groundwater pumping under control. This chapter presents the historical background and role of key individuals involved in achieving this goal, as well as lessons to be learned from these efforts.

Colonial difference is a story of national infrastructures. To understand how colonialism works across Indigenous lands, we need to appreciate the physical, legal, and political factors involved in the building and expanding of national infrastructures in different historical contexts; infrastructures that arrive in some places while denied in others. Using archival documents, this article accounts for the colonial politics necessary to bring Colorado River water into Phoenix and Tucson. It highlights how the following moments worked to enlarge Arizona’s population and power while denying Diné water claims: the 1922 Colorado Compact, Arizona’s 1960s campaign for the Central Arizona Project, and recent Indian water settlements between Arizona and Navajo Nation. The infrastructures that emerged from these events formed a coal–energy–water nexus reliant on Navajo coal while constructing Arizona’s water network. In sum, these projects served as colonial beachheads—temporal encroachments on Indigenous lands and livelihoods that augment material and political difference over time and exacerbate inequalities.

Colorado River Water

Environmental isotopes and water chemistry distinguish water types, aquifer recharge mechanisms, and flow paths in the Gran Desierto and Colorado River delta aquifer. The aquifer beneath the Gran Desierto supports a series of spring-fed wetlands, locally known as pozos, which have provided vital water resources to diverse flora and fauna and to travelers who visited the area for millennia. Stable isotope data shows that local recharge originates as winter precipitation, but is not the main source of water in the pozos. Instead, Colorado River water with substantial evaporation is the main component of water in the aquifer that feeds the pozos. Before infiltration, Colorado River water was partially evaporated in an arid wetland environment. Groundwater followed flow paths, created by the Altar Fault, into the current location of the pozos at Bahía Adair. Mixing with seawater is observed at the pozos located near the coast of the Gulf of California. The wetlands or other natural settings that allowed recharge to the aquifer feeding the pozos no longer exist. This leaves the pozos vulnerable to major groundwater pumping and development in the area.
