Montana Department of Environmental Quality

Big Dry Creek, Little Dry Creek, and Bullwhacker-Dog Watershed TMDL Watershed Study

  • ERG researched and compiled a characterization for the TMDL on this north central Montana water quality impaired stream for Montana Department of Environmental Quality (MDEQ).
  • The characterization covered all aspects of the watershed from geology, hydrology and vegetation to land use, cultural history and water use.
  • Fifteen thematic maps produced by ERG as part of the characterization used satellite derived coverages of land use, vegetation and other aspects of the watershed.
