About this map

Wolford Mountain Reservoir dominates the drainage patterns of this high country landscape in Grand County, where human-engineered water management intersects with natural creek systems. The modern topography is defined by significant impoundments including Hinman Reservoir, McElroy Reservoir, and the smaller Heini Reservoir, reflecting the region's historical and ongoing reliance on stored water for agricultural and local use.

A network of creeks, such as Muddy Cr, Antelope Cr, and Pinto Cr, feed into these basins, while the McMahon Ditch indicates the early development of irrigation infrastructure. This 2022 survey captures the character of the terrain just before it descends toward the Colorado River valley, revealing a landscape shaped by both natural features like Hay Gulch and the seasonal fluctuations of Alkali Slough.
