Freshwater Quality

Hourly measurements of water parameters are recorded during ice-free periods in selected park rivers. Parameters include temperature, pH, conductance, and dissolved oxygen. Any glacially-affected rivers also have turbidity measured. All original data, reports, and related materials are available for download here. Monitoring coverage began in spring 2010.

SEAN designed its long-term freshwater water quality monitoring program to fulfill these objectives:

  • Track the status and trends of each core water quality parameter.
  • Describe the timing and magnitude of seasonal and annual variation of each core water quality parameter.
  • Evaluate whether state and/or federal water quality standards are met or exceeded.
