Engineering Software and Spreadsheets

The public can obtain NRCS software from the NRCS Science and Technology Conservation Tools Software Website. The software provided in the table below is for use on NRCS platforms. The public should download the non-NRCS versions at the site listed above.

NRCS employees can access NRCS nationally approved software from the Information Technology Services staff (ITS).  Support for NRCS nationally approved engineering software should be obtained through the State Conservation Engineer.

The Montana Engineering Spreadsheet List table contains the approved list of Montana NRCS Engineering Spreadsheets. This list is dynamic and will be updated as existing Spreadsheets are revised or new Spreadsheets are added. Engineering computer Spreadsheets, developed by Montana NRCS employees not on the approved list should be sent to the State Conservation Engineer for review and approval.

The Montana Engineering Software List table contains the approved list of NRCS engineering software for use in Montana. This list is dynamic and will be updated as existing software is revised and new software is added to the list.
