2011 Map of Lemhi

About this map

Lemhi River valley life in the early 21st century is defined by its water management and transit routes. The small settlement of Lemhi serves as a central point along the path of Old Hwy 28, while the surrounding landscape is marked by the agricultural and conservation needs of the high desert. To the north, the Lemhi River Salmon Trap indicates the ongoing importance of the river's ecological health. The irrigation network is evidenced by the Ellsworth-Lower Dam on Yearian Creek and numerous smaller tributaries like Peterson Creek and Reese Creek. To the west, the terrain rises sharply into the foothills of Ramsey Mountain, carved by deep drainage features such as Struggle Gulch and D C Gulch. Local infrastructure is further detailed by rural ways including Lemhi Back Rd and Zeph Creek Rd, showing how modern ranches and homesteads access the river plains.
