2013 Map of Swan Lake

About this map

Swan Lake sits at the base of the Portneuf Range along the border of Bannock and Franklin counties, marking a significant hydrologic and transit corridor. The terrain is defined by dramatic elevation shifts, from the high peaks of Dry Hollow Mtn and Heart Mtn down through Hutchins Canyon to the valley floor. Irrigation infrastructure, including the Treasureton Canal, snakes across the eastern slopes, supporting the agricultural life of the region. The map details the scattered settlement patterns near Coulam and the open expanses of Poverty Flats to the south. Historically significant transport routes like Us 91 N and the surrounding network of local connectors like Stockton Rd follow the natural contours of the land, linking these small communities through the rugged Idaho landscape. Natural water features such as Swan Lake Slough and various mountain springs like Heart Mountain Spring provide essential water sources in this high-altitude environment.
