2010 Map of Rocky Knoll

About this map

Sevier River hydraulics dominate this high-desert landscape in Millard County, where the modern river course winds alongside the visible remnants of the Old Channel Sevier River. The intricate water management system is evidenced by numerous catchments including Hardpan Reservoir, Tamarack Reservoir, and Sevier Lake Reservoir Number 4, illustrating the region's reliance on irrigation and seasonal runoff. The topography is largely defined by the Old River Bed to the northeast and the intermittent drainage of Soap Wash, which cuts across the central flats. Human presence is concentrated along a sparse grid of rural roads such as S 18000 W and Squire Ln, providing access to the namesake Rocky Knoll and the nearby Rocky Knoll Springs. This 2010 survey documents the intersection of natural hydrology and man-made reservoirs in a remote section of the Sevier Desert.
