Paul Chobin Dam dam
Paul Chobin Dam
The Paul Chobin Dam, located in Oregon, stands at a height of 16 feet and serves as a significant water resource structure in the region. 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.

Condition Assessment
- Satisfactory
- No 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.
- 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.
- 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.
Hazard Potential Classification
- High
- Dams 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, environmental 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.

About Paul Chobin Dam
Where does the data for Paul Chobin Dam come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Significant hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
