2020 Map of Flagstaff Lake

About this map

Flagstaff Lake and the interconnected wetlands of the Warner Valley dominate this high desert basin in southeastern Oregon. This remote landscape is characterized by a series of shallow alkali basins, including Mugwump Lake, Swamp Lake, and Anderson Lake, which shift in size and presence based on seasonal runoff. To the east, the dramatic rising slopes of Hart Mtn provide a stark vertical contrast to the valley floor, while the Rabbit Hills anchor the northwestern corner of the quadrangle. The sparse road network, consisting of Hart Mountain Rd and Flagstaff Lake Rd, highlights the isolation of this region. The map reveals the intricate drainage patterns of Mulkey Canyon and the surrounding plateau, offering a detailed record of the hydrography and terrain of Lake County in the early 21st century.
