    • Model Archive Summary for a Suspended-Sediment Concentration Surrogate Regression Model for Station 405219124085601; Mad River Slough near Arcata, CA

    Metadata Updated: January 21, 2026

    Model archive summary (MAS) describing the development of a suspended-sediment concentration (SSC) surrogate regression model for the Mad River Slough near Arcata, CA water quality station (USGS site ID# 405219124085601). A 15-minute SSC record was computed using this regression model for the period of record (03-04-2016 to 09-10-2019). The computed SSC record can be found on NWIS Web at https://waterdata.usgs.gov/nwis/inventory/?site_no=405219124085601&agency_cd=USGS. The SSC record was used to assess ambient SSC conditions, the availability of suspended sediment to support surface deposition and elevation gain in adjacent salt marshes, and to characterize salt marsh resiliency to climate change impacts in Humboldt Bay, CA.
