2010 Map of Big Fill Reservoir

About this map

Grandview sits at the heart of this high-desert agricultural landscape, where an intricate network of irrigation systems defines the local economy and geography. The Highline Canal and Low Line Canal snake across the terrain, supplemented by numerous numbered laterals like Lateral E and Lateral F 1 that distribute water to the surrounding fields. This system of water management is anchored by the Big Fill Reservoir, a crucial piece of infrastructure that allows for farming in the arid region near Ryegrass Flat. The map reveals a rigid section-line road grid, including S 2600 W and W 1000 S, which dictates the layout of homesteads and acreage. This layout illustrates the early 21st-century state of Idaho's managed water landscapes, showing how essential these engineered waterways are to the survival and organization of the community.
