Cienega de Santa Clara; Deltaic Environment; Deltas; Fluvial Environment; Gran Desierto; Gulf of California; Irrigation; Isle Montague; Sea of Cortez; Sierra de Juarez; Water DiversionIn this image of the Colorado River Delta taken on September 8, 2000, irrigation and urban sprawl now prevent the river from reaching its final destination. The Colorado River can be seen in dark blue at the topmost central part of this image. The river comes to an end just south of the multicolored patchwork of farmlands in the northwestern corner of the image and then fans out at the base of the Sierra de Juarez. A hundred years ago the river would have cut through this entire picture and plowed straight through to the Gulf of California, the mouth of which can be seen in solid blue at the lower righthand corner of the image. The bluish purple river that appears to be flowing from the Gulf of California to the north is actually an inlet that formed in the bed of the Colorado River after it receded. The island at the entrance to the Gulf of California is the Isle Montague. The gray areas surrounding this inlet and the gulf itself are mud flats created by sediments once carried by the river. The flat yellow expanse to the east of the farms is the Gran Desierto. Between the farmland and the desert one can see a dark blue pool covered with patches of green. Known as Cienega de Santa Clara, this salt-water marsh formed by return irrigation is home to a huge population of birds.

Arid Environment; Ecology; Fluvial Environment; Fluvial Features; Habitat; Sonoran DesertThis is the Colorado River in the Cibola National Wildlife Refuge on the border between Arizona and California. The Cibola National Wildlife Refuge is located in the floodplain of the lower Colorado River and surrounded by a fringe of desert ridges and washes. The refuge encompasses both the historic Colorado River channel as well as a channelized portion constructed in the late 1960's. Along with these main waterbodies, several important backwaters are home to many wildlife species that reside in this portion of the Sonoran Desert.

Deposition; Floodplains; Fluvial Environment; Fluvial Features; Geomorphology; Hydrology; Irrigation; Surface Water; Water Diversion; Water SupplyNear its delta the Colorado River meanders slowly across its floodplain except where confined. Here deposition is greater than erosion and the waters are still being diverted for irrigation.
