2021 Map of Two Buttes Reservoir

About this map

The New Fork River winds through this section of Sublette County, defining a complex riparian landscape marked by Mack Island and a network of agricultural water management features. Irrigation infrastructure is central to the area's development, evidenced by the Bertram Ditch and Paradise Ditch which draw from the river system to support local ranching. The elevation rises toward the northwest at The Mesa, while the northern edge of the sheet is anchored by the Two Buttes Reservoir. This survey illustrates the modern intersection of natural drainage and human engineering, where roads like New Fork River Rd and Boulder South Rd navigate the contours of Sand Springs Draw and Alkali Cr.
