Abstract:
  This dataset contains streams listed in Montana's 2002 305(b) Report of water quality assessment determinations. It lists waters which have been assessed as fully supporting all applicable beneficial uses, waters determined to be water quality impaired for one or more beneficial uses, and waters where the information collected to date is not sufficient to complete beneficial use support determinations. The "On-list" attribute can be used to select streams on the 303(d) List of Impaired and Threatened Waters. The 303(d) List, required by the federal Clean Water Act, focuses on waters in the state which have been assessed as having one or more of their beneficial uses impaired by human-caused pollution.
Purpose:
  To allow users to query and display information from Montana's 305(b) Surface Water Quality Assessment Report. Appropriate for 1:100,000 scale use.

    Type of source media: electronic database
    Source contribution:
      The attributes of the streams and lakes were copied from this source.
    Calendar date: 2002
  Process step:
    USGS's NHD coverages (derived from USGS Digital Line Graphs) were used to identify the reaches composing each waterbody segment included in the 305(b) data set. Assessment information relating to each waterbody is drawn from the 2002 305(b) update of the Montana ADB database.
  Process date: 2002
