2021 Map of Poston
USGS Topo · Published 2021About this map
The Poston settlement and its surrounding agricultural infrastructure dominate this 2021 study of the Parker Valley. Located along the border between La Paz County, Arizona and Riverside County, California, the landscape is defined by the Colorado River and an extensive network of irrigation features. Canals and drains such as Lateral Number Seventy-nine, Leupp Lateral, and the Mesa Drain illustrate the engineered nature of this desert river valley, which relies on complex water management for its survival.
