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. 2009 ground condition Complete None planned -124.432591 -123.991559 43.203946 42.831951 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.

The channel centerline was reviewed and manually edited by team members to ensure that linework did not intersect bar features. Data are complete. Channel centerline 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. Centerlines were digitized along the center of the wetted channel. 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.

Channel centerlines were digitized along the center of the wetted channel through the study area using a polyline feature class. 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 polylines were intersected with a polygon feature class of the study reaches to limit mapping extent and assign reach names using the "Intersect" tool in ArcToolbox. 2011 Vector String 7 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_Centerline_2009 Mainstem, South Fork, Middle Fork, and North Fork Coquille River channel centerline 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 SHAPE_Length Length of feature in meters ESRI Positive real numbers that are automatically generated U.S. Geological Survey Ask USGS -- Water Webserver Team mailing
