1910 Map of Bouldin

About this map

The Sacramento-San Joaquin Delta is rendered in intricate detail during the 1908 survey, revealing a landscape defined by reclaimed islands and a complex network of sloughs. Extensive tracts like Mandeville Island, Venice Island, and Webb Tract dominate the terrain, separated by narrow channels such as Potato Slough and Sevenmile Slough. This survey captures the region's agricultural and industrial infrastructure just before the heavy modernization of the 20th century, noting features like the Old Cannery on the South Fork Mokelumne River and a Pumping Plant on Twitchell Island. Local commerce relies on river access, evidenced by Central Landing and Blakes Landing, which served as critical transit points for goods and people across the San Joaquin River. The map also preserves the specific hydrography of the era, including curious names like Big Brother Slough and Little Brother Slough.
