3 Characteristics Ownership Reach 1 has fairly even ownership with about 53% private and 47% public (U.S. Bureau of Reclamation, National Park Service, Washington State Department of Natural Resources, U.S. Forest Service,, and local government) with less than 0.01% tribal. Land Use/Current Shoreline Master Program Land Use Designation: Rural and Forest Current zoning designation: NR Forest, RA-10, and RA-20 Current Shoreline Master Program Environment Designation: Rural Parallel (Conservancy for 50 feet from the ordinary high water mark [OHWM], Rural for remaining 150 feet) Existing Land Cover/Development The Kettle River Reach consists of mostly forests and shrubland. Agriculture is prevalent in some areas, especially in SR 1c. Residential and agricultural structures are scattered along the shoreline throughout the reach, and roads are often within the shoreline, especially at crossings. Geomorphic Character Description n its upstream reaches, the Kettle River flows within a wide valley that is flanked by hill slopes that consist of bedrock of metavolcanics of the Rossland Group, Klondike Mountain Formation (continental sedimentary deposits and rocks), high-grade quartzite, marine metasedimentary rocks, and the Sanpoil Volcanic Formation. Channel and floodplain materials consist mostly of continental glacial drift and, to a lesser extent, alluvium. n the downstream reaches, the valley width generally narrows near the river s confluence with the Columbia River. Valley margins consist of a variety of crystalline rocks of igneous and metamorphic origin and, to a lesser extent, sedimentary rocks. Hardened Banks There are none identified. No artificial hardened banks were identified within Reach 1. Channel Migration Zone Along the Kettle River, the channel migration zone (CMZ) varies in width and generally is limited by topography. The CMZ is wider in areas where the valley widens and a broad floodplain exists. The CMZ narrows along segments where the river is adjacent to the valley margins.

4 Flooding and Geological Hazards Flooding Portions of this reach have mapped Federal Emergency Management Agency (FEMA) floodplains. n the areas where floodplains are mapped, floodplains widths are relatively narrow in areas where the river is less sinuous and relatively wide in areas where the river is more sinuous. Floodways are present in the upstream portion of SR 1b and consist of almost all of the floodplain area. Floodways are also present in the downstream portion of SR 1c. Floodplains in SR 1f are relatively wide and are also regulated by water levels in Lake Roosevelt. Geological Hazards Areas of unstable steep slopes (greater than 30%) and erosion-hazard areas exist along channel margins of left bank throughout the reach. Erosion-hazard areas were identified in all subreaches (SR 1a 1f) with the majority in SR 1d and 1e. The majority of the unstable steep slopes are in SR 1b and 1d and are associated with continental glacial drift with a minor amount of outwash and till in SR 1f. No active mines exist within the shoreline jurisdiction along the Kettle River. No known active faults exist along this reach. Existing Public Access Much of the Kettle River shoreline is privately owned, which limits public access. Hedland-Napoleon Road parallels the shoreline providing public access. Napoleon Bridge connects the shoreline to the west bank of the river in Ferry County. One boat launch and a parking area are located at the Napoleon Bridge site. Kettle River campground is located nearby on the west bank in Ferry County. dentified Public Access mprovements Public access improvements identified in the National Park Service s Lake Roosevelt National Recreation Area Shoreline Management Plan (Alternative B) include creating a new shoreline trail using existing linear features to connect Kettle River campground in Ferry County to Napoleon Bridge. Public Access Opportunities Public access opportunities are limited due to private ownership in the reach. Ecological Conditions Water Quantity and Sediment Reach 1 inflows from the side include Deep, Sand, Stevens, and Toulou creeks. Reach 1 inflows from the Ferry County side include Jenny, Little Boulder, Martin, East Deer, Boulder, Doyle, Matsen, and Deadman creeks. There also are numerous unnamed tributary inflows along the river. Flow data are collected in the Kettle River at the upstream extent of this reach near the United States-Canada border (U.S. Geological Survey [USGS] Gage # ), including instantaneous flow data. Based on historical records, peak flows occur during the late spring, and low flows occur during the late summer, early fall, and winter. Runoff from U.S. Route 395, local roadways, and adjacent agricultural lands may contribute flow into the river during the wet season and during periods of snowmelt. Sediment sources include steep, erodible glacial drift banks and soils prone to erosion that exists in SR 1a, 1b, 1c, 1d, and 1e. Additional sediment input sources likely include surface runoff and tributary inflow. Depositional features (mid-channel bars) exist throughout and are primarily present in SR 1c, 1e, and 1f.

5 Water Quality n SR 1b, recreational use from Matney Park may cause minor impacts to water quality. SR 1c has a tributary (Martin Creek) listed as a water of concern for bacteria on the Washington State Department of Ecology s (Ecology s) 305b list. SR 1d has a tributary (Deer Creek) that requires a Total Maximum Daily Load (TMDL) for dissolved oxygen. n SR 1e, TMDLs are required for ph and dissolved oxygen. These requirements are based on samples collected from Ecology Station #60A070, a long-term water quality station that has collected water quality data since At this station, Ecology states that overall water quality is of moderate concern (based on Water Year 2013 summaries). Water quality in all subreaches may be impacted by wildlife and agricultural, residential, and roadway runoff. Habitat Characteristics and Priority Habitat Species Presence SR 1a This subreach is adjacent to agricultural lands with crop or livestock areas extending almost to the river edge in many areas. Laurier-Lit Deep Creek Road crosses the Kettle River in the north end via a bridge and runs adjacent to the river for part of the center portion of the subreach. Riparian vegetation is limited or absent in areas adjacent to agriculture. There is a 1,000-foot-long island in the northern end with forest and sand. At the third river bend, near Laurier-Lit Deep Creek Road, the shoreline is steeper and the riparian and upland portion is forested. Northwest white-tailed deer use this area, particularly for severe winter habitat. SR 1b The shoreline along this subreach is mostly undeveloped and runs through predominately forested areas with scattered residential properties throughout the subreach and a few agricultural properties at the northern end most situated within 200 feet of the shoreline. Many of the residential properties are situated on bluffs, approximately 70 to 100 feet above the river, which limits access to the shoreline. At the southern end of the subreach, there is a bridge crossing of Rock Cut Road. Most of the riparian area is forested and connected with upland forest. The area immediately adjacent to the shoreline consists of sand with scattered grasses and shrubs. Northwest white-tailed deer use this area, particularly for severe winter habitat. SR 1c This subreach is adjacent to lands in agricultural use, as well as a segment that is partially forested with residential properties. Much of this development occurs within 200 feet of the shoreline. The Town of Orient is located on the west side of the river in this reach in Ferry County. There is a bridge crossing of Main Street (adjacent to the Town of Orient) that connects with Rock Cut Road, which parallels the river for approximately 1,200 feet near this intersection. Riparian vegetation in the subreach is varied with little to no riparian vegetation associated with agricultural areas and forested riparian in residential and non-developed areas. Additionally, in the bend just north of Orient, Washington, there is a 300-foot-wide sand bar with scattered shrubs. Another sand bar and moderately sized beach with scatted grasses and shrubs is located at the southern end. Northwest white-tailed deer use this area, particularly for severe winter habitat. SR 1d This subreach is mostly undeveloped with a few residential properties located in the north and south ends of the subreach, most set back from the shoreline more than 200 feet. The middle portion of the subreach is forested and associated with steep banks and a faster-flowing river. At the southern end, there appears to be a campground; however, this may be more an informal camping area. The riparian vegetation along the reach is mostly forest, which extends upland with some areas of sandy beach with grass and small shrubs.

6 Northwest white-tailed deer use this area, particularly for severe winter habitat. SR 1e This subreach has a medium-density winter habitat for Northwest white-tailed deer. Land use along this reach is a mixture of agriculture, residential, and undeveloped. Pierre Lake and Napoleon-Barstow roads parallel the river in the center of the subreach along the eastern end of the bend. There is a bridge crossing of Barstow Bridge Road in the center portion of the subreach. Riparian vegetation in this reach is varied with little to none associated with residential and agricultural areas. Undeveloped areas are associated with forest extending from the riparian into the upland. There is one large wetland with off-channel habitat in the center portion of the subreach and adjacent to agricultural land. This wetland contains forest, shrubs, and grasslands and appears to be periodically flooded. SR 1f The Kettle River converges with the Columbia River at the southern end of this subreach. The shorelines along this subreach are relatively undeveloped with a number of wetland complexes. The small amount of development in this reach is concentrated along Napoleon Barstow Road and occurs in the shoreline when the road also occurs in the shoreline. There are two bridge crossings on this reach one associated with Napoleon Road and the other is a railroad crossing. After the railroad crosses, the road the travels parallel to river, very close at portions, until the river converges with the Columbia River. Wetlands in this reach range from forested, shrubs, and emergent that may provide off-channel habitat. Northwest white-tailed deer use this are as winter habitat and can be found in medium density. Bald eagles and waterfowl also use this area in the winter for foraging, and waterfowl are can also be present in the fall.
