Suspended-Sediment Data for the Chehalis, Satsop and Wynoochee Rivers in Washington State, Water Years 2019-2022

This data release summarizes suspended sediment monitoring results on the Chehalis (USGS 12031000), Satsop (USGS 12035000) and Wynoochee (USGS 12037400) Rivers between water years 2019 and 2022. Sediment monitoring was based on a combination of continuous turbidity records 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, 2022. Metadata files within the zip files provide additional details on the file structure.
