This data release summarizes suspended sediment monitoring results on the Bogachiel (USGS 12042800) and Calawah (USGS 12043000) Rivers between water years 2019 and 2021, based on a combination of continuous turbidity monitoring and discrete suspended-sediment concentration (SSC) measurements. Data and results for each monitoring station were combined into zip files. Each zip file contains 1) summarized SSC measurements used in model calibration, 2) a detailed model archive summary documenting the process used to estimate SSC at 15-minute intervals, and 3) full 15-minute estimates of SSC and suspended loads between Oct. 1, 2018 and Sept 30, 2021. Metadata files within the zip files provide additional details on the file structure.
