  • Bank and Flowline GIS Data for 1950 (entire length of river corridor, MT), 1976 (Sweet Grass County to confluence with Missourri River), 1995 (Sweet Grass County to confluence with Missourri River), 2001 (entire length of river corridor, MT). and 2015 (Reed Point to Custer, MT)
  • 100-year Inundation Boundary GIS Data (2007)
• Geomorphic Parameters and GIS Development
  These two reports document the results of a GIS analysis performed in support of the geomorphic scope of work associated with the Yellowstone River Cumulative Effects Assessment. The work consists of a GIS-based summary of geomorphic planform parameters of the Yellowstone River corridor from Gardiner to the Missouri River confluence.  Primary reach breaks and reach classification data reflect those presented in the Geomorphic Reconnaissance and GIS Development for the Yellowstone River.

• Yellowstone River Geomorphic Analysis for Yellowstone County (2000)
  Prepared for the Yellowstone Conservation District by Womack and Associates, Inc. and Aquoneering, Inc., this report assesses the effects of erosion and flood control structures on the Yellowstone River’s geomorphology from the Carbon County line to the eastern edge of the Billings East USGS Quadrangle. Principal sources of data include historic aerial photography (1957 and 1999) and survey data obtained by the report authors (1999) and the US Army Corps of Engineers (1968).
