Large-scale agriculture and intricate irrigation define the Merced County landscape south of the San Joaquin River. Following a 1946 revision of earlier 1916 mapping, the terrain reveals a transition from natural watercourses like the Pick Anderson Slough and Arroyo Slough to an engineered network of waterways, including the Colony Main Canal and Toscano Ditch. This infrastructure supported named operations such as Delta Ranch, San Juan Ranch, and No 1 Devon Farm.
