Playa Wetlands of the Southern Great Plains

The Southern Great Plains playa lake and wetland region covers the semiarid Llano Panhandle Estacado (Southern High Plains) of the Texas Panhandle and adjacent eastern New Mexico. It extends north of the Canadian River through the Oklahoma Panhandle into southwest Kansas and southeast Colorado. The main geologic feature of the playa region is the underlying Ogallala Aquifer, which supplies irrigation water often collected in playas as runoff from irrigated fields.
