Most of this area is cropland or improved pasture that is extensively irrigated, but large acreages are in range.
Major crops are cotton, grain sorghum, citrus, onions, cabbage, and other truck crops.
The range is mainly grazed by beef cattle and wildlife. Hunting leases for quail, white-winged dove, and mourning dove are an important source of income. Major land use problems are saline soils and inadequate subsurface drainage on cropland. Much of the area is nearly level. Drainageways are shallow and have low gradients.
