About this map

The high plains of the Carbon and Albany County border are defined by a complex network of water management features designed to sustain this arid Wyoming landscape. Water from Rock Creek and the Rock River is diverted through a series of named irrigation works, including the Bosler Ditch Number 3, Big Harrison Ditch, and the John White Enlargement Ditch. These systems feed crucial local storage sites such as Whiskey Number 1 Reservoir and the namesake Pierce Reservoir.

Evidence of early regional transit remains visible in the alignment of Old State Hwy 13, while secondary routes like Cooper Cove Rd provide access to the terrain's intermittent drainages. The landscape is carved by numerous creeks and draws, from Threemile Creek to Frank Draw, illustrating how ranching and water rights have historically shaped the settlement patterns of this section of the Laramie Plains.
