About this map

The low-lying islands of the California Delta dominate this 1910 survey, showcasing a complex network of waterways that defined early Sacramento Valley commerce. Isleton and Walnut Grove appear as vital riverfront hubs during a period when the delta was being aggressively reclaimed for agriculture. The map illustrates the intensive levee and drainage systems required to transform places like Andrus Island, Grand Island, and Staten Island into productive farmland.

Along the Sacramento River, industrial activity is anchored by the Golden State Cannery at the southern edge of the quadrangle. Transport and trade patterns are visible through numerous landings and waterway junctions, including Georgiana Slough and Steamboat Slough, which bypass the main river channel. The interface of the Mokelumne River and its various forks highlights the intricate hydrology that necessitated early riverboat stops like Ryde and Walker Landing.
