About this map

The Imperial Valley landscape dominates this 2021 study, revealing the intricate water management infrastructure essential to this arid agricultural region. A complex network of irrigation arteries, including the Westside Main Canal and Fillaree Canal, crisscrosses the terrain, branching into numerous laterals and drains. The presence of the New River at the southern edge of the sheet provides a natural contrast to the engineered grid of canals like the Thistle Canal and Riley Canal.

This grid-based system is defined by a dense array of rural roads such as Imler Rd, Edgar Rd, and Wheeler Rd, which facilitate access to the surrounding fields. The sheer density of labeled drainage and lateral lines, such as Tokay Drain One and Thistle Lateral Eight, illustrates the massive scale of human intervention required to sustain the valley's productivity. Local family-named routes like Pellett Rd and Hoskins Rd further define the land divisions in this intensely cultivated corner of Imperial County.
