The Southeast Alaska Network (SEAN) long-term streamflow monitoring program is implemented in collaboration with a suite of partners including the U.S. Geological Survey (USGS), the City and Borough of Skagway, the City and Borough of Sitka, the Alaska Department of Natural Resources, the National Weather Service, and the Central Office of the NPS Inventory and Monitoring Program. The SEAN contributes funds for USGS operation of gages on the Taiya (Klondike Gold Rush NHP) and Indian Rivers (Sitka NHP). The USGS sustains two other gages within Glacier Bay NP&P on the Alsek and Salmon Rivers. The objectives of the SEAN program include:

  • Quantify long-term changes or trends in annual and seasonal patterns of streamflow in the Indian, Taiya, and Salmon Rivers.
  • Monitor streamflow relative to existing water rights and reservations (Indian River).
  • Contribute critical information for flood forecasting and other public uses.
  • Relate streamflow to patterns of water quality to help interpret results and to enable computation of chemical loads (Indian, Taiya, and Salmon Rivers; also see the SEAN Freshwater Water Quality Vital Sign).
