2023 Map of Coglan Buttes

USGS Topo · Published 2023

About this map

Upper Chewaucan Marsh dominates this landscape in Lake County, defining a complex hydrologic network of irrigation and drainage infrastructure. This 2023 survey illustrates the heavy modification of the basin, where the Chewaucan River is diverted and managed through an intricate system of canals and ditches. Named features such as the ZX Brattain Ditch, Red House Ditch, and Jones Canal reveal the legacy of ranching and water management in the Oregon high desert. To the east, the elevation rises sharply toward the Coglan Buttes, creating a stark vertical contrast to the marshy lowlands below. The presence of features like Shores Waterhole and local routes like Lovers Ln provide specific points of interest for those tracing the geographic history of this wetland environment.
