1990 Map of Little Valley

USGS Topo · Published 1990

About this map

Harper and the surrounding high desert terrain of Malheur County are documented in this late 20th-century survey, which details the complex water management systems essential to life in Little Valley. The Malheur River and Bully Creek serve as the primary hydrologic features, supported by an intricate network of canals, siphons, and a levee designed to direct water across the arid landscape. Evidence of earlier infrastructure is visible in the north with an Abandoned Canal winding through the hills near Jordan Ranch.
