Annual EAP Update

An Emergency Action Plan (EAP) is a formal document that identifies potential emergency conditions at a dam and specifies preplanned actions to be followed to minimize property damage and loss of life in the event of a dam failure. The dam safety program encourages dam owners of all hazard classification dams to create an EAP. Owners of existing or proposed dams classified as high hazard-potential are required to create and maintain an EAP.

The OWRB Emergency Action Plan Guidelines for High-Hazard Potential Dams fact sheet includes a description of all of the six elements of an EAP. The OWRB Dam Safety Forms & Publications section also includes a fillable EAP form that can be used when updating or creating new EAPs. 

Along with accurate up to-date information, EAPs must also include a concurrences signature page, in order to be filed with the OWRB. These signatures help ensure that the correct law enforcement, engineering, and emergency management offices have received copies of the document, and will be properly prepared in the event of dam failure. 

**All EAP documents are required to be reviewed/updated by the dam owner annually to ensure that the current data, contact information, and signatures are up-to-date and accurate. If you have any EAP related questions please contact the the OWRB Dam Safety Program staff.**


Operation and Maintenance Plan

To ensure safe functioning of dams and to extend their life, the OWRB recommends that dam owners develop dam operations and maintenance plans for their dams.

Operation and maintenance plans should include the routine maintenance practices and expected frequency. For more information on how to prepare an operation and maintenance plan, please refer to the ASDSO video Developing Operation and Maintenance Manuals for Dams-2014  or the OWRB Dam Maintenance Guidelines document.
