About this map

Poso Farm and the surrounding agricultural lands straddle the boundary of Madera and Fresno counties, defined by the winding course of the San Joaquin River. This 1962 survey, updated in the early 1980s, reveals a complex irrigation and drainage network essential to Central Valley farming, featuring the Columbia Canal, Central Canal, and numerous sloughs like Berenda Slough and Lone Willow Slough. The landscape is a grid of section lines and access roads such as Oxalis Ave and Silaxo Ave, punctuated by storage bins and isolated wells.

The Southern Pacific railroad cuts through the southwestern corner, paralleling the Main Canal near the Silaxo Drain. In the southern reaches of the map, the Raisin City Gun Club sits near the confluence of the Buttonwillow Slough and the Branch Columbia Canal, highlighting the area's use for both industrial agriculture and seasonal recreation. This document preserves the precise hydraulic and transport footprints of the region before further modern expansion altered these rural townships.
