Soil logs, grain size analysis, and Pebble Count at West Fork Hoquiam River Dam Removal and Groundwater Replacement Preliminary Design and Permitting project from 2023-09-24 to 2023-09-30 (NCEI Accession 0306764)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Metadata Last Checked: October 04, 2025 | Last Modified: 2025-08-12T00:00:00.000+00:00

The data set contains pebble count data for transects located directly downstream of the Hoquiam Dam. The dataset was used to inform hydraulic design (channel restoration, erosion rates, and other key parameters). Additionally, the data set includes sediment coring and grain size analyses for transects upstream of the dam to verify estimates of sediment thickness and characterize the grain-size of sediment impounded by the Dam.
