The low-lying reclaimed lands of the Contra Costa and San Joaquin County border define this 1952 study. This complex aquatic landscape is characterized by its numerous tracts and islands, including the Orwood Tract, Woodward Island, and Victoria Island, all separated by a network of waterways like the Old River and Middle River. Human engineering is pervasive throughout the delta, shown through the massive Mokelumne Aqueduct, numerous siphons, and an intricate system of levees and pump houses that protect the agricultural tracts.
