Silvies Valley dominates the northern landscape of this Oregon interior, where the Silvies River and its accompanying West Side Ditch define the local water management. The terrain transitions from the valley floor into the timbered slopes of Malheur National Forest to the south. Numerous natural water sources, such as Buffalo Lake, Owen Spring, and Smith Spring, are vital markers in this high-elevation environment.
