1990 Map of Malheur Lake East

USGS Topo · Published 1990

About this map

Malheur National Wildlife Refuge dominates this high-desert landscape in southeastern Oregon, where the fluctuating waters of Malheur Lake meet the eastern edge of the Harney Valley. The map details a transition from the marshy expanses and islands like Pelican Island and Cole Island to the elevated terrain of Black Butte and Black Butte Ridge. This 1990 provisional survey records a landscape defined by water management and ranching, evidenced by the scattered Stock Pond and Stock Tank locations across the flats. The shoreline data, sourced from mid-1970s and early-1980s aerial photography, captures the variable nature of the lake's boundaries, providing an important record for those studying the hydrologic history and land use of this protected habitat south of the South of Malheur Lake region.
