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.

The area dealt with in this report is that portion of northwestern Sonora and southwestern Arizona bounded on the southwest by the Gulf of California, on the west by the Colorado River valley below the junction of the Gila River, on the north by the Gila River valley, and on the east by an imaginary line from the vicinity of Gila Bend south along the western edge of the Papago Reservation and thence southwest to the mouth of the Sonoyta River on the Gulf of California (Fig. 106). Within this area Sauer has suggested a boundary between the Piman-speaking people of southern Arizona and northern Sonora, and the Yuman-speaking tribes of the lower Colorado and Gila River valleys, based on linguistic affiliations described in early historical sources (Sauer 1934, map). On archaeological evidence Gifford has suggested that the locality between Punta La Cholla and the mouth of the Sonoyta River represented a point on an ethnic boundary (Gifford 1946: 221).

AbstractFreshwater lakes existed intermittently in the Salton Trough of southern California during the late Holocene. The lakes formed north of the subaerial Colorado River Delta whenever the Colorado River flowed west into the trough instead of south to the Gulf of California. Water filled the trough to a maximum altitude of 12 m. Stratigraphy, radiocarbon dates, and supplementary evidence document four lacustral intervals of Lake Cahuilla between A.D. 700 and 1580. Archaeological sites are associated with the 12-m shoreline and their occupation correlates with these lacustral intervals.
