2012 Map of Prado Dam

About this map

Prado Dam and the sprawling flood basin of the Santa Ana River anchor this 2012 topographic record of the Chino Valley's edge. The landscape transitions from the dense suburban residential patterns of Los Serranos and Chino Hills into a corridor of preserved history and open space. Notable landmarks include the Yorba Slaughter Adobe and the Boys Republic campus, while the Chino Airport marks the eastern industrial margin. The southern half of the map is defined by a network of drainage canyons including Slaughter Canyon, Abacherli Canyon, and Banie Canyon, which cut through the uplift of San Juan Hill. This survey provides a clear view of the intersection between massive regional infrastructure and the legacy of the area's earlier ranching days, evidenced by the McDermont Ranch and Rolling M Ranch.
