2014 Map of Preston Reservoir

About this map

The White River Valley defines the landscape of this high-desert basin, where drainage patterns and water management are the primary markers of human presence. In the southern reach, the Preston Reservoir sits as a vital water source, while further north the Giroux Wash Reservoir provides another point of surface water accumulation. The terrain is marked by seasonal and ephemeral watercourses including Giroux Wash, Jakes Wash, and Holt Cr, which channel runoff from the surrounding uplands toward the valley floor. Dark Peak rises as a prominent landmark in the northeast, overlooking the intersection of these drainages. This survey captures the arid character of eastern Nevada, highlighting the essential role of localized reservoirs and creek systems in a region defined by its hydrography and high-altitude valleys.
