Willow Creek Valley dominates the western portion of this Lassen County landscape, characterized by its wide wetland basins and seasonal water storage. The 2021 topography reveals a specialized network of high-elevation water management, where Streshley Reservoir and Hagata Reservoir collect runoff from the surrounding peaks. This area serves as a critical catchment for the local watershed, with the narrow Hagata Canyon and Long Canyon channeling water from the steep slopes of Horse Lake Mtn and Tunnison Mtn.
