Open-file Reports are available as free downloads or on CD/DVD-ROM (see below).

Most of the reports are PDF files and require the free Adobe Acrobat Reader software to view. These reports may also contain GIS data or other file types, and some are collections of files that are intended to run from a CD-ROM or local hard drive.


These reports are subject to frequent revisions and may be unavailable when being modified. The Last Modified date listed here reflects when a file was last saved and may not be the date this report was last revised.

All files listed in the CDROM directory below are necessary for an interactive report on CD or local hard disk to run as intended. Note that all features of some Open-file Reports intended to run from a CD-ROM will function on Mac or Linux systems.
