The Iowa DNR is responsible for the state's dam safety program. The program involves the review and approval for the construction of new dams, maintaining an inventory of existing dams that meet minimum size criteria and the periodic inspection of certain dams. Currently there are approximately 3800 dams on the state's dam inventory. Dams that have the potential to create extensive damage to downstream houses or buildings, or to cause loss of life should they fail and release their impounded water are required to be regularly inspected. There are currently 321 dams that require regular inspections either on a 2 or 5 year inspection frequency. Permits may be required to construct a dam, modify an existing dam, drawdown the water level, or remove a dam. In these cases, please review the Permit Application Process. For more information, please contact: Jon Garton (515-725-8360; Jonathan.Garton@dnr.iowa.gov OR Casey Welty (515-725-8330; Casey.Welty@dnr.iowa.gov
Dam Inspection Guidance
Dam Inspection Checklist
Being prepared in the event of an emergency is one of the most important responsibilities of a dam owner. The Federal Dam Safety Guidelines and the National Dam Safety Program Act, passed by Congress in 1996, and reauthorized in 2006, both consider a well planned and coordinated EAP to be an essential responsibility of the owner.
It has long been established that having an EAP reduces the potential for loss of life downstream of dams. The dam owner can be held responsible and liable for loss of life caused by failure of the dam. Compliance with government or professional standards does not necessarily absolve an owner from liability, but it does establish a standard of care to be used by owners.
The EAP accomplishes three important objectives:
As the dam owner, you are responsible for developing and maintaining the EAP and for updating it on annual basis. The importance of meeting with your local emergency management agencies at least once a year cannot be overstated. This meeting ensures that everyone understands the EAP, including pre-planned emergency procedures and inundation maps. Once completed, the EAP should be submitted to this office for review and approval.
