Model Archive Summary (MAS), "382829121351801_LIS_ExtendedMAS.docx", describing the development of a continuous, 15-minute suspended-sediment concentration (SSC) time series regression model for the site: Toe Drain Near Babel Slough Near Freeport, California (U.S. Geological Survey (USGS) site #382829121351801). The SSC time series is computed from instream turbidity data that is managed by the California Department of Water Resources (CDWR) using a YSI 6-series multi-parameter water quality sonde. Complete methods for turbidity data collection and model development are described in the attached methods document (MAS).
