About this map

Agricultural lifelines dominate this portion of the San Joaquin Central Valley, where an intricate network of irrigation infrastructure supports the regional economy. The landscape is defined by the massive Delta-Mendota Canal and the Colony Main Canal, which feed a grid of smaller waterways including Poso Slough and Laguna Canal. These systems facilitate the industrial-scale farming that spans the Merced and Fresno county line.

Small settlements like Dos Palos and Oxalis serve as local anchors within this highly engineered environment. The map details the transition from residential streets to long, straight rural routes such as Merrill Ave and Fairfax Ave. This 2021 survey provides a clear view of the modern water management system, tracing the flow of the First Lift Canal and various drainage features like the Holland Drain and Silaxo Drain that maintain the valley's productivity.
