O'Connor, Jim E. Keith, Mackenzie K. Mangano, Joseph F. Wallick, J. Rose 2012 U.S. Geological Survey Open-File Report 2012-1064 Reston, Virginia U.S. Geological Survey 84 p. http://pubs.usgs.gov/of/2012/1064/ The Coquille River system is an unregulated system that encompasses 2,745 square kilometers of southwestern Oregon and flows into the Pacific Ocean near the town of Bandon, Oregon. Beginning in the Rogue River-Siskiyou National Forest, the South Fork Coquille River gains the Middle Fork Coquille River (drainage area 798 square kilometers) and shortly thereafter the North Fork Coquille River (749 square kilometers). In cooperation with the U.S. Army Corps of Engineers, the U.S. Geological Survey completed a reconnaissance-level assessment of channel condition and bed-material transport relevant to the permitting of in-stream gravel extraction along the the South Fork Coquille River from river kilometer (RKM) 115.4 near its confluence with Upper Land Creek to RKM 58.5 at its confluence with the North Fork Coquille River, the mainstem Coquille River from RKM 58.5 at the confluence of the South and North Forks of the Coquille River to its mouth, the Middle Fork Coquille River from RKM 15.4 to its confluence with the South Fork Coquille River, and the North Fork Coquille River from RKM 14.6 to its confluence with the South Fork Coquille River. To support these analyses, digital channel maps were produced to depict channel and floodplain conditions in the Coquille River basin from different time periods. GIS layers defining the wetted channel and bar features and channel centerline of Hunter Creek were developed for four time periods: 1939, 1967, 2005, and 2009. For this project, the active channel was defined as area typically inundated during annual high flows, and includes the low-flow channel as well as side channels, islands, and channel-flanking gravel bars. The wetted channel and bar feature datasets were developed by digitizing from aerial photographs. Aerial photographs from 1939 and 1967 were scanned, rectified, and mosaicked for this project (See metadata for each photograph set for more information on the rectification process and resolution of each dataset). Digital orthophotographs from 2005 and 2009 are publicly available. These data were created to support preliminary assessment of channel stability and bed-material transport on Coquille, Middle Fork Coquille, and North Fork Coquille Rivers, southwest Oregon. This mapping was used to track changes in channel morphology and planform over time. 1967 ground condition Complete None planned -124.433052 -123.991531 43.204364 42.831921 None sediment transport fluvial geomorphology historical channel change channel stability ISO 19115 Topic Categories inlandWaters Geographic Names Information System (GNIS) Coquille River North Fork Coquille River Oregon Coast Range Curry County South Fork Coquille River Coos County Middle Fork Coquille River None The U.S. Geological Survey should be acknowledged as the data source in products derived from these data.

Data are topologically correct in ArcGIS. Topolgy rules were used to edit features and verify that polygons were completely enclosed or did not overlap. Data are complete. Wetted channel and bar feature mapping was reviewed by a minimum of three other team members to ensure protocol was followed and that mapping was consistent between time periods. Digitizing was done at a scale of 1:3,000 on the South, Middle, and North Fork Coquille Rivers and upstream of river kilometer 24.8 on on the Coquille River. Downstream of river kilometer 24.8 on the Coquille River, digitizing was completed at a scale of 1:10,000. All bar and wetted channel features greater than 300 square meters were digitized. Because polygons were split for assignment to study reaches, some may represent areas less than 300 square meters. Best judgment was used to delineate feature boundaries where obscured by vegetation or shadows. The 1939 and 1967 photographs were georectified with a minimum of eight ground-control points concentrated near the main channel and rectified with a second-order polynomial transformation. The total root mean square error values of the rectified photographs from 1939 and 1967 indicated that horizontal-position uncertainties associated with the georectification process ranged from 1.4 to 6.4 meters for individual photographs, but averaged 3.2 meters for the 1939 photographs and 3.4 meters for the 1967 photographs. Because control points were concentrated near the channel, error associated with mapped features along channel corridor should be lower than the total root mean square error values for the entire photograph. Digitizing was done at a scale of 1:3,000 on the South, Middle, and North Fork Coquille Rivers and upstream of river kilometer 24.8 on on the Coquille River. Downstream of river kilometer 24.8 on the Coquille River, digitizing was completed at a scale of 1:10,000. Wallick, J. Rose Jim E.

U.S. Deparment of Agriculutre unknown remote sensing image 20000 aerial photograph 19670508 19670525 ground condition USDA 1967 The aerial photographs provided a base layer from which channel features were delineated. The 1939 and 1967 photographs were georectified with a minimum of eight ground-control points concentrated near the main channel and rectified with a second-order polynomial transformation. The total root mean square error values of the rectified photographs from 1939 and 1967 indicated that horizontal-position uncertainties associated with the georectification process ranged from 1.4 to 6.4 meters for individual photographs, but averaged 3.2 meters for the 1939 photographs and 3.4 meters for the 1967 photographs. Because control points were concentrated near the channel, error associated with mapped features along channel corridor should be lower than the total root mean square error values for the entire photograph. 2011 An ESRI geodatabase topology rule of “must not overlap" was used for editing. This required that no bar feauture polygons encountered the same space. 2011 Bars visible in aerial photographs were outlined using a polygon feature class. The outline was drawn to represent the feature as seen at a scale of 1:3,000 in fluvial reaches and 1:10,000 in tidal reaches. All bar features within the study area greater than 300 square meters were digitzed. 2011 Wetted channel edges visible in aerial photographs were outlined using a polyline feature class. Line ends were snapped to existing bar polygons. 2011 Delineation of bars, channel centerlines, and wetted-channel edges was verified by project team members to ensure consistent delineation of features among years and throughout the study area and consistency with the delineation protocol of Wallick and others (2011). 2011 The bar polygon feature class was converted to points using the “Feature To Point” tool in ArcToolbox. 2011 The bar polygon and wetted channel polyline feature classes were converted to polygons using the “Features To Polygon” tool in ArcToolbox. The bar point feature class was used to label those polygons with the correct attribute information. 2011 The polygons were intersected with a polygon feature class of the study reaches to limit mapping extent and assign reach names to the polygons using the "Intersect" tool in ArcToolbox. 2011 The wetted channel feature polygons were manually labeled in the attribute table. 2011 Vector GT-polygon composed of chains 281 Transverse Mercator 0.9996 -123.0 0.0 500000.0 0.0 coordinate pair 0.0001 0.0001 Meter D North American 1983 GRS 1980 6378137.0 298.257222101 ofr2012_1064_Coquille_River_Wetted_Channel_and_Bar_Features_1967 Mainstem, South Fork, Middle Fork, and North Fork Coquille River bars and wetted channel U.S. Geological Survey OBJECTID Internal feature number ESRI Sequential unique whole numbers that are automatically generated SHAPE Feature geometry ESRI Coordinates defining the features River Mainstem channel that contains the feature object U.S. Geological Survey Coquille Mainstem Coquille River between river kilometer 58.5 and 0.0 U.S. Geological Survey South Fork Coquille South Fork Coquille River between river kilometer 115.4 and 58.5 U.S. Geological Survey Middle Fork Coquille Middle Fork Coquille River between river kilometer 15.4 and 0.0 U.S. Geological Survey North Fork Coquille Mainstem Illinois River between river kilometer 6.5 and 0.0 U.S. Geological Survey Reach_ID Study reach that contains the feature object U.S. Geological Survey Powers South Fork Coquille River between river kilometer 115.4 and 96.9 U.S. Geological Survey Broadbent South Fork Coquille River between river kilometer 96.9 and 66.2 U.S. Geological Survey Myrtle Point South Fork Coquille River between river kilometer 66.2 and 58.5 U.S. Geological Survey Bandon Coquille River between river kilometer 58.5 and 0.0 U.S. Geological Survey Bridge Middle Fork Coquille River between river kilometer 15.4 and 0.0 U.S. Geological Survey Gravelford North Fork Coquille River between river kilometer 14.6 and 0.0 U.S. Geological Survey Feature Geomorphic classification of channel features U.S. Geological Survey Bar Lateral and medial bars composed of gravel and finer sediment within the active channel and possibly mudflats and marshes in tidal reaches that were exposed and above the water surface during aerial photograph acquisition.
