2021 Map of Poso Farm

About this map

The San Joaquin River snakes through this agricultural landscape, forming the natural boundary between Fresno and Madera Counties. This section of the Central San Joaquin Valley is defined by a sophisticated network of water management, where natural features like Berenda Slough, Lone Willow Slough, and Buttonwillow Slough interface with engineered systems. To the west, the Poso Canal, Central Canal, and numerous drainage channels such as Poso Drain One support the intense cultivation of the valley floor. In the southwest corner, the map reaches the outskirts of Firebaugh, showing the intersection of Main St and N Dos Palos Rd near the River Br Columbia Canal. The grid of rural roads, including Triangle T Rd and Hemlock Rd, illustrates the organized expansion of ranching and farming operations across this fertile alluvial plain.
