2023 Map of Guano Lake

USGS Topo · Published 2023

About this map

Guano Valley and the prominent escarpment of Shirk Rim dominate this high-desert landscape in Lake County. The drainage patterns of Jack Creek and Guano Creek define the low-lying basins, which are dotted with seasonal water bodies such as Jack Lake, Egg Lake, and Corral Lake. This terrain reflects a classic Great Basin hydrology where water collects in shallow depressions like Shirk Lake and Round Lake rather than reaching the sea. Access is limited to Bureau of Land Management routes, including BLM RD 7136-0-00 and BLM RD 6106-0-00, which navigate the elevation changes between the valley floor and the surrounding plateaus. The inclusion of Little Reservoir suggests historical efforts to manage water resources for livestock in this arid environment.
