Data for Turbidity, Discharge, and Suspended-Sediment Concentrations and Loads, Duwamish River, Tukwila, Washington This data release includes turbidity, discharge, suspended-sediment concentration (SSC) and particle-size data that were collected by the U.S. Geological Survey (USGS) between February 2013 and January 2017 at the Duwamish River, Washington, within the tidal influence at river kilometer 16.7 (USGS site 12113390; Duwamish River at Golf Course at Tukwila, WA). Additionally included in this release are the regression model archive summaries (MAS) that were developed between SSC and turbidity as well as SSC and discharge to estimate 15-minute SSC. Suspended-sediment loads were calculated from the computed SSC and time-series discharge data for every 15-minute interval during the study period.

Although there is an adequate supply of freshwater in the reservoir, there are taste-and-odor water-quality concerns. The U.S. Geological Survey (USGS) worked in cooperation with the Charleston Water System to study the hydrology and water-quality of the Bushy Park Reservoir to identify factors affecting water-quality conditions.

The measurement period was 10 March, 2017 to 1 March, 2019. The USGS sensors were co-located with sensors for nitrate and specific conductance operated by University of New Hampshire (UNH), and these datasets are all used in the accompanying publication. A 4-month gap in turbidity in 2018 was mostly filled by UNH data, using a relation between USGS turbidity and co-located UNH turbidity when both sensors were operating.

A DTS-12 turbidity sensor (Forest Technology Systems) at the streamgage measured turbidity at 15-minute intervals. Suspended-sediment samples were collected at the streamgage over a range of discharge and turbidity conditions. Regression equations were developed to estimate the suspended-sediment concentration (SSC) and the concentration of fine suspended-sediment (fSSC; <0.0625 mm) using turbidity as an explanatory variable. A 15-minute time series of SSC, fSSC, and the uncertainty of individual estimates (prediction intervals with 90 percent confidence) was...
