2015 Map of Poso Farm

About this map

The San Joaquin River winds through the heart of the San Joaquin Valley on this 2015 survey, defining the boundary between Fresno and Madera Counties. The landscape is dominated by a complex network of irrigation and drainage infrastructure essential to the region's agricultural productivity, including the Poso Canal, Central Canal, and the River Br-Columbia Canal. This hydraulic engineering is juxtaposed with natural watercourses like Berenda Slough and Lone Willow Slough, which meander across the flat terrain. The city of Firebaugh occupies the southwestern corner of the sheet, serving as a primary hub for the surrounding farmlands. Smaller agricultural outposts like Poso Farm are connected by a rigid grid of rural roads, such as Avenue 17 and Road 9, which facilitate the movement of goods and equipment through these productive fields.
