2023 Map of Guano Reservoir
USGS Topo · Published 2023About this map
Guano Reservoir sits at the heart of this high desert landscape, serving as a critical hydrological focal point within the broader Catlow Valley. The drainage patterns are defined by the winding course of Guano Slough, which meanders across the basin toward the reservoir, and the steep descent of Black Canyon to the southwest. This 2023 survey illustrates the remote character of the Harney County interior, where the terrain transitions from the prominent heights of Cox Butte down to the expansive valley floor.
