USGS Topo · Published 1936About this map
The San Joaquin River meanders through this Central Valley landscape, creating a complex network of sloughs and cutoffs like the Finigan Cutoff and Baird Slough. Surveyed just before the mid-century water projects reshaped the region, the map shows the confluence where the Tuolumne River joins the main channel near Tuolumne City. The importance of water management in this agricultural era is evident at the Vanormer Pumping Sta and the irrigation patterns appearing near Rancho Del Puerto.
