The map highlights the intensive water management system required for the region, featuring named canals and drains such as the Central Main Canal, Eucalyptus Canal, and Dahlia Canal. These waterways dictate the layout of the land, with roads like S Clark Rd and Pitzer Rd following the precise geometry of the fields.
