2017 Map of Poison Creek Slough

About this map

The E Fork Silvies River and its complex network of seasonal waterways dominate this portion of the High Desert landscape in Harney County. The area is characterized by an intricate drainage system of sloughs, including Poison Creek Slough, Embrace Slough, and Foleys Slough, which weave through the flat terrain south of Sand Hill. This drainage pattern reflects the region's hydrologic dependency on the Silvies River system for agriculture and ranching, evidenced by the presence of the Upper Hanley Canal. Cultural developments are concentrated near the regional hub, with the Burns Municipal Airport serving as a prominent landmark. The road network, featuring routes like Crane Blvd and Hwy 20, cuts across the lowlands, while named paths such as Old Experiment Rd and Rye Grass Ln provide access to the rural sections of the Harney Basin.
