2018 Map of Poso Farm

About this map

The San Joaquin River snakes through the heart of the Central Valley on this 2018 survey, defining the agricultural character of western Fresno and Madera counties. The landscape is a complex network of irrigation and drainage infrastructure, dominated by the Poso Canal, Central Canal, and the River Br Columbia Canal. These man-made waterways operate alongside natural features like Poso Slough and Lone Willow Slough, illustrating the century-long effort to manage water in the San Joaquin Valley. The city of Firebaugh anchors the southwest corner, while Poso Farm represents the larger industrial agricultural operations that characterize the region. A rigid grid of rural roads, including Triangle T Rd and W Oxalis Ave, segments the fertile plains, providing access to the vast fields that sustain the local economy.
