About this map

The Snake River defines the northeastern boundary of this Idaho landscape, where the river's path is punctuated by Fruit Island, Dilley Island, and Cottontail Island. This contemporary survey illustrates the complex water management systems vital to the region, including the Deer Flat Low Line Canal, Conroy Lateral, and Opalene Ditch. These man-made features contrast with the natural drainages of Opalene Gulch and Rats Nest Gulch.

Protection of the riverine habitat is evident through the Deer Flat National Wildlife Refuge, while the interior terrain rises toward prominent landmarks like Elephant Butte and the distinctively named Shares Snout in the Shares Basin. Isolated water sources such as Alkali Spring and Coyote Spring are marked across the arid high ground, providing essential reference points for those tracking the historical land use and natural history of the Canyon and Owyhee county border.
