2015 Map of Mendota Dam

About this map

The San Joaquin River carves a winding path across this portion of the San Joaquin Valley, where the hydrological management of the Central Valley is on clear display. At the heart of this irrigation network sits the Mendota Dam, a critical point where the river meets the Fresno Slough. This intersection reflects the intensive agricultural engineering of the region, supported by a grid of named water works including Helm Ditch, Ridge Ditch, and the Lone Willow Slough. To the south, the city of Mendota serves as a local hub, anchored by the William Robert Johnston Municipal Airport. The map also captures the administrative boundary between Madera Co and Fresno Co, while the local transit network is defined by long, straight thoroughfares such as Firebaugh Blvd and Belmont Ave.
