Methods

The methods followed in the creation of the dataset, including description of field, laboratory and processing steps, and quality control procedures

Current Methods

  • Sampling in streams and lakes
    Started: 1982-03-01

    Sampling in streams using dip method. Sampling in lakes using center flow method, using kemmerer bottle at 1m depth and 1m from bottom.

  • Seasonal sampling
    Started: 1982-03-01

    Spring, summer and fall sampling of lakes and streams.

  • Measurements
    Started: 1982-03-01

    Measurements include: field pH, Lab pH, gran alkalinity, specific conductance, calcium, magnesium, soldium, potassium, aluminum (both speciated organic and monmeric, and total dissolved), nitrate, sulfate, chloride.

  • Secchi disk readings
    Started: 1982-03-01

    Lakes sampled for secchi disk readings.
