    • Sediment inorganic chemistry data and sediment descriptions

    Metadata Updated: November 13, 2025

    Four sediment cores were collected from the San Juan Generation Station reservoir. The sediments from each of these cores were described for physical properties and analyzed for inorganic elements. These data provide the initial field observations of reservoir sediments including grain size, color, and reaction with hydrogen peroxide and hydrochloric acid. Sediment inorganic chemistry data are also provided.
