2018 Map of Thornton

About this map

The settlement of Thornton sits at the junction of the Mokelumne River and a complex network of sloughs and canals that define the fertile border between the Sacramento Valley and the San Joaquin Valley. This landscape is characterized by the intricate waterways of the California Delta, including the expansive Staten Island and various drainage features like Beaver Slough, Hog Slough, and Sycamore Slough. The rural economy is visible through the grid of local roads such as W Woodbridge Rd and Jacob Brack Rd, which support the extensive irrigation infrastructure of the Northwest Main Canal and W Main Canal. This 2018 survey highlights the continued reliance on levees and managed water systems, notably along Levee Rd, to maintain the agricultural productivity of this low-lying region.
