2021 Map of Mendota Dam

About this map

The San Joaquin River meanders through the heart of the Central Valley on the border of Fresno and Madera Counties. This agricultural landscape is defined by its complex irrigation and flood control network, featuring the Mendota Pool and the Eastside Bypass. The city of Mendota serves as a primary hub in the southwest corner of the map, situated near the William Robert Johnston Municipal Airport. The mapping reveals the transition from natural waterways like Lone Willow Slough and Fresno Slough to engineered infrastructure such as Chowchilla Canal Rd and Ridge Ditch. These features illustrate the managed water systems necessary for industrial-scale farming in the San Joaquin Valley during the early twenty-first century.
