About this map

The San Joaquin River and a complex network of man-made waterways define this Central Valley landscape in the early 1980s. Major agricultural and transit hubs like Mendota, Firebaugh, and Madera anchor a grid of irrigation infrastructure, including the Delta-Mendota Canal, California Aqueduct, and Eastside Bypass. This map captures the region's total transformation into a hydraulic powerhouse, where natural flows like Fresno Slough and Cottonwood Creek meet the engineering of the Main Canal and Outside Canal.

To the west, the flat valley floor gives way to the stark topography of the Panoche Hills and Ciervo Hills, separated by the broad drainage of Panoche Creek. For local historians and genealogists, the map preserves the locations of smaller rural settlements such as Tranquillity, Ripperdan, and Oro Loma. Notable landmarks include the Mendota Waterfowl Management Area and aviation sites like Eagle Field Airport, tracing the intersection of land management, rail transport via the Southern Pacific, and aviation in this productive interior.
