The low-lying wetland landscape of Harney County is defined by the diverging channels of the E Fork Silvies River and W Fork Silvies River. This 2020 survey illustrates a complex hydrologic network where the river system spreads into features like Square Well Slough and Black Slough. The small settlement of Lawen serves as the central hub for the area's rural road network, which includes Crane Blvd and S Harney Rd. Man-made water management is evident through the Ausmus Canal, reflecting the ongoing efforts to direct water across this flat, seasonally inundated basin. The map reveals how local infrastructure, such as Embree Bridge Rd and Lawen Dump Rd, navigates the intricate balance between usable land and the expansive drainage of the Silvies River delta.
