Persons who construct, alter, remove or operate a non-federal dam must obtain approval from the Tennessee Division of Water Resources, Dams Section. A dam is defined as a structure at least 20 feet high or holds 30 acre-feet or more of water at maximum pool.
Any dam that meets the size requirements above and is used exclusively as a farm pond (not used by the public) is not regulated by the Division and is not required to have approval.
Non-federal dams may also require other environmental permits. Specifically, non-federal dams may require an ARAP (Aquatic Resource Alteration Permit), Stormwater Runoff Permit, and/or a Corps of Engineers' 404 Permit even though the dam may not be subject to the Safe Dams Act. The permits listed on this web-site are not intended to be an all-inclusive list. If you have any question about whether or not an activity you wish to pursue requires a permit, contact the Environmental Permit Program that you think may have permitting authority over the activity you wish to do or contact your Environmental Field Office for further assistance.
