2020 Map of Nichols Reservoir

About this map

Craters Of The Moon National Preserve occupies the southern half of this landscape, marking a stark volcanic interface with the agricultural and riparian systems to the north. Located in the Big Lost River Valley, the area is defined by its water management and drainage patterns. The northern reaches show an organized grid of section lines and water infrastructure, including the Blaine Canal and Moore Canal, which draw from the regional watershed to support the valley floor. To the west, the terrain rises toward several seasonal watercourses and local landmarks like Tephick Spring. The map documents the specific boundary where the protected volcanic wilderness meets the human-managed landscape of Butte County, Idaho. Minor drainages such as Timbered Dome Cr and Champagne Cr provide essential topographical detail for understanding the local hydrology and its relation to the highway corridors that traverse the valley.
