The South Platte River corridor defines the geography of this Weld County region, where a complex network of irrigation infrastructure supports the agricultural valley. The town of Fort Lupton serves as the central hub, surrounded by an intricate system of water management including the Fulton Ditch, Brantner Ditch, and Brighton Ditch. These waterways, alongside several smaller laterals and canals, illustrate the intensive land use required for high-plains farming.
