Iowa City Iowa 52240 319-335-1353 319- gis_library@igsb.uiowa.edu This digital, geographically referenced data set was developed by the Iowa Department of Natural Resources to carry out agency responsibilities related to management, protection, and development of Iowa's natural resources. It resides in the Natural Resources Geographic Information System library. Although efforts have been made to make it useful to the Department, the Department assumes no responsibility for errors in the information. Similarly the Department assumes no responsibility for the consequences of inappropriate uses or interpretations of the data made by anyone to whom this data has been made available. The Department bears no responsibility to inform users of any changes made to this data. Anyone using this data is advised that precision implied by the coverage may far exceed actual precision. Comments on this data are invited and the Department would appreciate that documented errors be brought to staff attention. The development of the coverages in the NRGIS Library represents a major investment of staff time and effort. As a professional responsibility, we expect that the Iowa DNR will receive proper credit when you utilize these GIS coverages and that the original documentation will remain with any redistribution of these coverages.
