2020 Map of Poison Creek Slough

About this map

Burns Municipal Airport anchors the north-central portion of this Harney County landscape, a region defined by the complex hydrology of the Silvies River delta system. The terrain is characterized by a network of seasonal waterways and irrigation works, including Poison Cr Slough, Foley Slough, and the Upper Hanley Canal. To the north, the topographic relief of Sand Hill provides a rare point of elevation above the surrounding marshes and meadows. The road network, featuring names like Old Experiment Station Rd and Substation Rd, reflects the area's agricultural infrastructure and land management history. Tracing the path of the E Fork Silvies River and Embree Slough reveals the intricate water management essential to this high-desert environment in the modern era.
