Summary
Despite being privately owned and not regulated by the state, the dam has a high hazard potential and is considered to be in "significant" condition. The last inspection in December 2018 revealed that the dam is not currently rated, highlighting the need for further assessment and potential risk management measures to ensure the safety and stability of the structure.
Situated in Washington County, Oregon, the Paul Chobin Dam plays a crucial role in managing water resources in the area, although specific details regarding its purposes and design remain unknown. The dam's location in the Portland District contributes to its importance in the region's water infrastructure, with an inspection frequency of every three years to monitor its condition and assess any potential risks. The dam's association with emergency preparedness, such as the existence of an Emergency Action Plan (EAP), has not been disclosed, indicating a potential area for improvement in terms of risk management and response protocols.
As a key feature in the local water system, the Paul Chobin Dam warrants ongoing attention and evaluation to ensure its continued safe operation and effectiveness in water resource management. With its significant hazard potential and lack of state regulation, the dam presents a unique challenge in balancing the need for water storage and flood control with the safety and protection of surrounding communities. Continued monitoring, assessment, and potential risk management measures will be essential to safeguard the integrity and functionality of this vital water infrastructure asset.

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.
