Summary

These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. Geomorphic mapping establishes the basic context for understanding modern channel conditions by (1) defining major elements of the late Cenozoic geologic history shaping the geomorphology of the study area; and (2) outlining the active geomorphic floodplain, which is the domain for assessing channel change and floodplain vegetation conditions. The mapping domain broadly corresponds with the extent of Light Detection and Ranging (LiDAR) topography acquired [...]

Purpose

The overall objective of this study of the Sprague River basin is to provide understanding on (1) recent changes to the fluvial systems of the basin, (2) important geomorphic processes and conditions, and (3) their spatial variability and controls. The primary focus of our analysis was the 139 kilometers (km) of the mainstem Sprague River, the lower 16 km of the North Fork Sprague River, the lower 20 km of the South Fork Sprague River, and the lower 20 km of the Sycan River. Collectively, this part of the river network encompasses most of the low gradient reaches historically subject to agriculture and livestock grazing, as well as more recent channel restoration activities. Our analyses and findings were supported by (1) mapping and measurement of channel and floodplain features from historical maps and aerial photographs, and by high resolution LiDAR topography acquired in 2004, (2) stratigraphic measurements and analyses of floodplain deposits, (3) surveying the effects of 2006 high flows, and (4) geomorphic mapping based on soils, sedimentology and topography.
