Canonie Environmental 19940330 Helena, Montana Montana State Library The former name of this data set on the NRIS web site was "hd50" http://mslapps.mt.gov/Geographic_Information/Data/DataList/datalist_Details.aspx?did={33b14155-3366-42a0-b50c-1e21d5224fe0} 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data were formerly available from the Montana State Library web site but were removed because they are potentially out of date.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. 19930722 Publication Date Complete -112.806198 -112.568604 46.1325989 45.9892998 -112.794,46.1244,-112.7664,46.0181,-112.5583,46.0048,-112.5594,45.9922,-112.8133,46.0026,-112.8162,46.125,-112.794,46.1244 ISO 19115 Topic Category geoscientificInformation inlandWaters groundwater water elevation Montana MT Silver Bow None The Montana State Library provides this product/service for informational purposes only.
