An overview of regional hydrology is presented for the greater Bristol Bay drainages based on published government information. Localized hydrology for the mine study area is described in detail based on extensive streamflow gauging and snow survey programs. Data on localized hydrology for the transportation-corridor are presented as estimates, with some site-specific input.

Elements

  • Pebble scientists utilized 26 continuous gauging hydrology stations to gather information on stream-flow, supplementing that information with four additional United States Geological Survey administered stations.
