Niobrara River suspended-sediment and bed-sediment data collected during hydroelectric dam flush near Spencer, Nebr., October through November, 2014 In the fall of 2014 (October-November) the U.S. Geological Survey in cooperation with the U.S. Army Corps of Engineers collected sediment samples (suspended and bed material) at several sites on the Niobrara River in Nebraska near the Spencer Dam prior to, during, and immediately after a sediment-flushing event. Suspended-sediment samples were analyzed for sediment concentration and percent finer than sand. Bed sediment samples were analyzed for particle-size distribution using standard classes by sieve analysis. In addition, a Sequoia LISST Streamside particle-size analyzer (PSA) was deployed during the first week of the flush; this unit collected suspended-sediment concentration and grain-size data. Sampled sites...

Reflectance measurements were made by wading the Niobrara River near Norden Notch using an Analytical Spectral Devices FieldSpec3 spectroradiometer operated in reflectance mode.
