Free Low Hazard Dam Inspections

Registration is now open for free low hazard-potential dam inspections. The OWRB's free low hazard dam inspection offer includes an on-site inspection, full inspection report, and a breach inundation map. Dam owners benefit from this program because state law requires them to complete a dam inspection every five years. Dam owners can also take advantage of this opportunity to learn more about the inspection and maintenance techniques in order to prolong the life of their dam and manage their liabilities as dam owners. Contact Emma Moradi at (405) 530-8800 or for more information.
