Abstract:

These data are isolines of groundwater elevation along Silver Bow Creek. The lines were interpolated by hand by Canonie Environmental based on data from monitoring wells. The data was edited at the State Library based on instructions from Canonie. The original data imported from the Canonie DXF files is distributed with the final data in a shapefile called "Old_Version".

These data were formerly available from the Montana State Library web site but were removed because they are potentially out of date. Please contact the Federal Superfund Bureau of the Montana Department of Environmental Quality if you want these data so they may tell you if newer or better data are available. If the data are not available from the Department of Environmental Quality, you may request a copy from the Montana State Library data archive.
