Harney Valley is defined by a complex hydrology of braided waterways and low-lying land in this southeastern Oregon survey. The East Fork Silvies River and West Fork Silvies River dominate the drainage pattern, supplemented by seasonal or stagnant water features like Black Slough and Square Well Slough. This network of forks and sloughs creates a distinctively fluid landscape where the water is often as prominent as the land itself.
