Sprague River Oregon Centerline Sycan circa 1870

Dataset Identification:

Resource Abstract:
The Sprague River drains 4090 square kilometers in south-central Oregon before flowing into the Williamson River and upper Klamath Lake. In cooperation with the U.S. Fish and Wildlife Service, the USGS and University of Oregon conducted a study to evaluate channel and floodplain processes for the 131 km of the Sprague River and its major tributaries, including the lower 20 km of the South Fork Sprague River, the lower 16 km of the North Fork Sprague River, and the lower 62 km of the Sycan River. The study involved multiple analyses, including assessments of historical channel change, riparian and floodplain vegetation, and surficial geology. To support these analyses, digital floodplain and channel maps were prepared from historic notes, maps, and aerial photos to depict channel and floodplain conditions at different times between 1866 and 2005. The geospatial database of current and historic channel and floodplain conditions will also enable evaluation of long-term trends pertaining to aquatic and riparian habitat conditions.

purpose:
These data were created to support understanding of geomorphic conditions and historical changes to channel and floodplain conditions for the Sprague River and the lower portions of its major tributaries. GIS layers depicting channel centerlines, water features, fluvial bars, floodplain vegetation, and floodplain features such as irrigation canals, levees and dikes, and roads were created from aerial photographs dating from 1940, 1968, and 2000. The purpose of this mapping was to track changes in channel and floodplain morphology and vegetation over time and to measure changes in channel position. Historical aerial photographs from 1940 and 1968 were acquired, scanned, and rectified for this project, while digital orthophotographs from 2000 are publicly available. (See metadata for each photograph set for more information on the rectification process and resolution of each dataset). In addition, channel centerlines were mapped from publicly available coverages for 1975 (Natural Resources Conservation Service Soil Survey of Klamath County) and 2005 (U.S. Department of Agriculture NAIP imagery). The surficial geologic mapping was done to support understanding of the geologic context of the modern floodplain, and encompasses the alluvial valleys of the Sprague River and the lower portions of the Sycan, North Fork, and South Fork Sprague Rivers.

evaluation Method Description  A goal of an RMSE less than 5 meters was established for the georectification process. Photo scanning and DPI were calculated to ensure that 2000, 1968, and 1940 photo sets all had the same 1 meter pixel resolution.

Completeness Commission
evaluation Method Description  Data are complete. River centerline is defined as a line digitized by eye that approximates the centerline of the Primary Channel for the Sprague, North Fork Sprague, South Fork Sprague and Sycan Rivers. Five different river centerlines were digitized from five year sets (1940s, 1968, 1975, 2000, 2005). For digitized year sets 1940s, 1968 & 2000, mid-channel bar features were ignored when delineating the centerline. Centerline was established as the point between the channel edges.

ConceptualConsistency
measure Description  Topology rules were used to clean and edit features digitized within the floodplain boundary data set for overlap and boundary accuracy. A separate topology was run to edit digitizing overlap with the floodplain boundary data set and the features digitized within it to ensure all features were enclosed within the final floodplain boundary.
