Middle Rogue Sub-basin
The Middle Rogue sub-basin is a watershed covering 881-square miles in the middle of the larger Rogue River watershed. The most densely populated areas of the Rogue basin are within the Middle Rogue sub-basin, both in Jackson County on the western side of the watershed, and Josephine County on the eastern edge. Upstream is the Upper Rogue sub-basin and downstream the watershed drains into the Lower Rogue.
The northern and southern portions of the watershed are higher elevation conifer forests, draining the slopes of the Siskiyou Mountains in the south and the Umpqua divide to the north. There are small parts of the watershed managed by the U.S. Forest Service, predominantly along Evans and Ashland Creeks, with the BLM owning a checkerboard of land parcels in the mid and lower elevation land. The overwhelming majority of property within this sub-basin is privately owned and used for timberlands, agriculture, small industry and urban development.
Major tributaries to the Rogue River in this sub-basin include Bear, Evans, Sams, Sardine, Jackson, Griffin, Foots and Whetstone Creeks. Towns in the watershed contain most of the population of the entire Rogue Basin and include Medford, White City, Central Point, Jacksonville, Phoenix, Talent, Ashland, Gold Hill, Rogue River and Grants Pass.
Various threats to aquatic ecosystems are apparent in and around these population centers. In the Middle Rogue sub-basin, Rogue Riverkeeper works to address industrial pollution, industrial, construction and municipal stormwater and bacteria pollution, while also advocating for better stream flows and water conservation.
