1978 Map of Holt

About this map

The San Joaquin River and the Stockton Deep Water Channel define the low-lying agricultural landscape of the San Joaquin Delta in this 1978 survey. This region is a complex network of reclaimed tracts and islands, including the Rindge Tract, Lower Jones Tract, and Roberts Island. Transportation and infrastructure are vital to these islands, evidenced by the Atchison Topeka and Santa Fe railroad cutting through the center and the McDonald Island Fy providing a river crossing. Small communities like Holt and Union Point serve as local hubs, while educational needs are met by the Holt Union Sch and Kingston School. The presence of the Mokelumne Aqueduct and numerous pumping stations underscores the intensive water management required to maintain these fertile tracts. Industrial activity is noted by a Gas Field and the U S Naval Reservation Rough and Ready on the eastern edge.
