1966 Map of Eightmile Lake

About this map

The Continental Divide winds through this high desert landscape, marking the hydrological split between the Sweetwater and Carbon county lines. The area is defined by a series of significant basins and water features, including the prominent Eightmile Lake, Fivemile Lake, and the sprawling Coal Bank Lake to the south. The terrain is dominated by the long ridge of Big Hill, which dictates the flow of numerous seasonal drainages like Echo Springs Draw, Horse Pasture Draw, and Coal Bank Draw. Evidence of the region's resource-based activity is scattered across the sheet, from the Storage Bins near Echo Springs to a Drill Hole located further south. This 1960s survey documents a transitional era of land use where natural springs like the simple Spring and Echo Springs provided vital water in an otherwise arid expanse, complemented by man-made infrastructure like the Government Reservoir.
