2023 Map of Poison Creek

About this map

The Silvies River and its complex network of seasonal waterways define this high desert landscape in Harney County. The river meanders through the western portion of the map, flanked by Foley Slough and Fivemile Slough, which suggest a floodplain subject to significant seasonal shifts. These water features are vital landmarks in an otherwise arid region, where ranching and resource management are evident in the presence of Arntz Reservoir and various water improvements like Coal Pit Spring and Black Spring.
