Dam Design: Plans and Specifications

Oregon Statute 540.400 provides specific exemption for state design review of hydraulic structures with height less than 10 feet or storage less than 3 million gallons (9.2 acre-feet).  All other hydraulic structures that exceed both of these height and storage dimensions require design review and approval by the state dam safety program prior to construction.
 
Oregon does not have prescriptive standards for the design of dams, reservoirs or other hydraulic structures.  Oregon does require that the design must be prepared by a professional engineer who is registered with the state licensing board (OSBEELS) or designed by any other licensed professional engineer in the employment of the federal government.  The following items constitute the minimum design requirements for examination of design plans and technical specifications for construction of hydraulic structures:  This portion of the page is currently under revision.  If you have questions please email us damsafety@wrd.state.or.us
