Agricultural and water management infrastructure dominates this Central Valley landscape near Ingomar. The settlement pattern is defined by large-scale ranching and dairy operations, including Ingomar Ranch, M and C Dairy, and D and D Holsteins Dairy. A complex network of irrigation and drainage channels, such as the Santa Fe Canal, Rubino Ditch, and Kesterson Ditch, crisscrosses the low-lying terrain, highlighting the engineered nature of the region's hydrology. Natural and man-made water features converge here, with Mud Slough and San Luis Creek flowing toward the San Luis Holding Reservoir. The grid of rural roads, including Ingomar Road and Pfizer Road, provides access to these isolated agricultural sites, while the San Luis Wasteway and San Luis Spillway Ditch manage the essential flow of water through the Merced County plains.
