The Old River and Coney Island define this complex delta landscape at the junction of Alameda, Contra Costa, and San Joaquin counties. The area reflects a transition from early rail-based settlements like Bethany and Herdlyn along the Southern Pacific tracks to massive mid-century water infrastructure projects. The California Aqueduct and Delta-Mendota Canal dominate the terrain, drawing from the Delta Pumping Plant and feeding the Bethany Reservoir.
