    • Water quality data - North Puget Sound Chinook salmon captive propagation

    Metadata Updated: May 24, 2025

    NOAA Fisheries is a cooperator with the Washington Department of Fish and Wildlife and the Lummi, Nooksack, and Stillaguamish Tribes in a 10-year program to rebuild the South Fork Nooksack River spring Chinook and Stillaguamish River fall Chinook stocks through a captive broodstock program. Nitrate(mg/l), nitrite (mg/l), ammonia (mg/l), pH, temperature (Celsius), and dissolved oxygen (mg/l) are routinely measured for tanks used to culture Nooksack and Stilliquamh Chinook, Redfish Lake Sockeye, and Elwha Pink salmon. Water flow (gpm), water clarity, oxygen (on/off), feeding behavior, and cleaning comments are also noted. Measurements are taken weekly at random, except when scheduling conflicts arise. There can be up to 12 dissolved oxygen samples from Building 22 and up to 17 from Building 13. Additional data collected from 4 liter water samples includes classifying invertebrate content down to order. Fish sloughage, spicules, organic matter, ciliates and crustaceans are qualitatively assessed. Spicule types(s), crustacean type(s) and ciliate type(s) are recorded. A text box for microscope comments is present.
