For statewide map above and zoom maps below:
 

  • Modified from the ERDAS data set of the Michigan State University Center for Remote Sensing.
  • Base from U.S. Geological Survey 1:500,000 Lambert conformal conic projection provided by the Midcontinent Mapping Center of the Earth Science Information Center.
  • Base digitized by David Westjohn and Tom Weaver.
  • 17,921 1-km-squared pixels define drainage based on the Michigan Hydrologic Unit Map (1974) of the U.S. Geological Survey.
  • Pixels reduced from ERDAS set by Gary Huffman to minimally define confluences and headlands.
  • Pixels downstream and Horton ordered using CANOE.FOR by John Hoaglund.


  • Northern Michigan Rivers
    1st Order = Blue
    2nd Order = Green
    3rd Order = Yellow
    4th Order = Orange
    5th Order = Red
