Published Soil Surveys for Idaho

Soil surveys issued prior to 2008 are archive copies that are not compatible with the screen-reader software used by the visually impaired. For accessibility assistance, email nrcs-spsd-508@usda.gov or call (402) 437-5499.

Current, official soil survey information is on the Web Soil Survey. The Web Soil Survey allows you to create custom reports by selecting a specific area of interest, such as a county, national park, or your property. In the table below, clicking on a survey area that is listed as “current” takes you to the Web Soil Survey.

Historical and supplemental documents are also available below. Printed soil survey reports were the main source of soils information from 1899 to 2005. Most of these reports are county-based, have been converted to PDF, and are available from links below. The reports are also available at Federal depository libraries. USDA phased out the printing of reports after making Web Soil Survey the official source for information in 2005.

To view the soil maps of archived soil survey reports, use the Firefox browser. Chrome, Edge, and other browsers do not support the links. For help accessing these historical maps, click here.

In some cases, the published reports are available at local USDA offices. For information about reference copies of a publication or for information about publications that are not on the following list, contact the State Conservationist.
