2012 Map of Pierce Reservoir

About this map

Diamond Dome Gas Field defines the northern reaches of this Wyoming landscape, illustrating the intersection of energy extraction and high-plains ranching. The territory is a network of water management systems essential for agricultural survival, featuring an extensive array of irrigation works like the Big Heart Ditch, Whites Rock Creek Ditch, and Bosler Ditch Number 3. These man-made channels support a series of family-named holdings, including Diamond Ranch, Banzhof Ranch, and Double K Ranch, which are situated near the seasonal flows of Threemile Cr and Coalbank Cr. The central basin is dominated by Pierce Reservoir and Little Pierce Reservoir, critical landmarks in an area where water rights and access dictate the layout of roads such as Old State Hwy 13. The map offers a precise view of early 21st-century land use, where natural drainages like Frank Draw are heavily modified by historic water claims.
