2017 Map of Rocky Knoll

About this map

The Sevier River winds through this arid expanse of Millard County, defining a landscape shaped by water management and natural drainage. This modern survey highlights the complex hydrology of the region, where the Old Channel Sevier River remains visible alongside active features like Tamarack Reservoir and Hardpan Reservoir. The terrain is punctuated by the namesake Rocky Knoll and the nearby Rocky Knoll Spring, offering a look at the essential water sources that have long dictated land use in this desert environment. Human infrastructure is represented by a sparse network of roads, including the Highway 257 Cutoff Rd, which cuts across the township and range boundaries. In the south, the presence of Sevier Lake Reservoir Number 4 further illustrates the ongoing efforts to capture and redirect runoff in this dry basin.
