Ennis Lake dominates the upper reach of the Madison River valley, serving as a focal point for both industry and early tourism in the Madison Range foothills. The presence of the Old Madison Powerhouse and the newer Madison Powerhouse downstream from the dam highlights the region's role in early hydroelectric development. The valley floor is defined by an expansive Alluvial Fan and a complex irrigation network of ditches, such as Moores Ditch and West Fork Ditch, which support several family-named ranching operations including the Shelhamer Ranch and the H Lazy B Ranch.
