Description: Underwater photographs were acquired on the Upper Columbia River (UCR) in October-November 2018 and July 2019 in support of the Upper Columbia Remedial Investigation and Feasibility Study (RI/FS). The field survey methods are detailed in the Field Survey Report (FSR). Underwater photographs were acquired at predefined point locations (stations) positioned along predefined river transects. Following data acquisition, the underwater images were processed using Adobe Lightroom and ImageJ software for quantitative, semi-automated sediment grain size analysis. Statistics from each underwater image were calculated to produce a percent composition for each sediment grain size classification, including fine-grained sediment (grain size <2 millimeters (mm) including sand, mud, silt, and clay), gravel (grain size 2 - 64 mm), cobbles and boulders (grain size > 64 mm) and bedrock. The image locations and interpreted sediment composition data were exported to an ESRI shapefile. The data processing methods are detailed in the Data Summary Report (DSR).
