Without gathering any data, a map in ArcGIS would be nothing; so it is very important to find good data. There are various websites that have data to use in ArcGIS, however I will lead you into one particular site for this tutorial: http://www.igsb.uiowa.edu/nrgislibx/ This website was developed by the Iowa Department of Natural Resources, and is a Natural Resource GIS Library with a plethora of GIS data pertaining to the state of Iowa.
Once you are on the website you will be able to download data via a compressed zip folder. For this specific map, there will be various files that you will need to download.
