Ryer Island, Grand Island, and Staten Island dominate this 1952 topographic study of the Sacramento-San Joaquin River Delta. This era captures the intricate relationship between agricultural reclamation and the massive water engineering projects of the mid-20th century. The Delta Cross Channel is shown north of Walnut Grove, a critical component for diverting water from the Sacramento River toward the pumps of the south. Settlements such as Locke and Ryde line the levees, reflecting the river-oriented development of the region.
