1997 Map of Lima Dam

About this map

Lima Reservoir dominates the southern reaches of this landscape, its expansive waters contained by the Lima Dam Spillway 6577. Situated within the Centennial Valley of Beaverhead County, this 1997 revision highlights a transition from high-altitude desert basin to the steep elevations of the Clover Divide. The hydrologic network here is central to the area's utility, with the Red Rock River feeding the reservoir and a Gaging Sta monitoring the flows essential for downstream ranching. To the north, the terrain rises into the Beaverhead National Forest, where numerous drainages like Blacktail Deer Creek and Clover Creek carve through the high country. This document serves as a critical record of water management and forest boundaries in the Montana backcountry, detailing the remote Trail systems and spring-fed creeks that define the region's geography.
