The shape and depth of Iliamna and Iniskin bays, tidal range and currents, wave and ice-scour action in the vicinity, and a brief analysis of some of the inputs to and outputs from the bays are addressed through literature searches of previous study results and through field investigations. Marine water quality data for physical and chemical parameters sampled in the field from 2004 through 2008 are presented, and the results for the inorganic chemical parameters are compared to the Environmental Protection Agency’s National Recommended Water Quality Criteria to give context.


  • 327 physical water quality measurements were recorded in the Cook Inlet study area between 2004 and 2008
