2015 Map of Oxalis

About this map

Agricultural infrastructure dominates the landscape of the San Joaquin Valley south of Dos Palos, where a complex network of irrigation and drainage systems supports the region's farms. This 2015 survey reveals the engineered hydrology necessary for large-scale cultivation, featuring the prominent Delta-Mendota Canal and numerous secondary waterways like the Colony Main Canal and Laguna Canal. The small settlement of Oxalis sits along a primary road artery, serving as a landmark in a terrain defined by a precise grid of rural roads such as Merrill Ave and Brannon Rd. The boundary between Merced Co and Fresno Co bisects the northern sections, cutting through fields drained by the Poso Slough and Holland Drain. This map illustrates the intersection of administrative lines and water management that has shaped the modern development of the Central Valley.
