Vermont Dam Inventory

The Vermont Dam Inventory (VDI) is a database containing spatial, structural, historic, and regulatory information on most dams in Vermont.

*Data from VDI is managed by the VT Dam Safety Program. It is important to note that select fields in the VDI are linked to the ANR Atlas - Dams Layer. This is updated near-real time when updates are made to the VDI database.  

The Dam Safety Program uses the VDI to keep record of pertinent information for each structure in the database. The program is continuously striving to make the data as comprehensive and accurate as possible. 

If you are navigating the VDI and happen to find something that isn't accurate or contains outdated information, please send an e-mail to our general mailbox - This e-mail is regularly monitored by the Dam Safety Program, and we will respond in a timely manner.
