Summary
Built in 1926, this earth dam stands at a height of 32 feet and boasts a storage capacity of 70 acre-feet, making it a key player in the local water resource management system. Despite its age, the dam is in fair condition and is regularly inspected and maintained by the Oregon Water Resources Department to ensure its continued functionality and safety.
With a surface area of 4.9 acres and a drainage area of 1.39 square miles, the Strong dam plays a crucial role in managing water flow and ensuring adequate irrigation for the surrounding area. The dam's high hazard potential underscores the importance of effective risk management measures, prompting ongoing assessments and emergency preparedness protocols. Owned and regulated by private entities, the Strong dam exemplifies the collaborative efforts required to sustainably manage water resources in a changing climate.
As a key component of the local water infrastructure, the Strong dam reflects the intersection of natural resource conservation and agricultural needs in Oregon. Its strategic location and purposeful design highlight the importance of balancing human development with environmental stewardship in the face of evolving climate challenges. With its history of service and commitment to operational excellence, the Strong dam stands as a testament to the enduring resilience of water resource management in the Pacific Northwest.

Dam Data Reference
Condition Assessment
SatisfactoryNo existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
