Port Townsend Paper Asb Pond dam
Port Townsend Paper Asb Pond
Located in Jefferson, Washington, the Port Townsend Paper Asb Pond is a privately owned offstream dam completed in 1978 with a primary purpose of "Other." Standing at a hydraulic height of 28 feet and a structural height of 17 feet, this earth dam with a stone core sits on a soil foundation. With a normal storage capacity of 550 acre-feet and a maximum storage capacity of 615 acre-feet, the dam covers a surface area of 31 acres and serves a drainage area of 0.05 square miles.
Managed by the Washington Department of Ecology, this dam is state regulated, inspected, and enforced, ensuring compliance with safety and environmental standards. The last inspection in 2016 deemed the dam's condition satisfactory with a significant hazard potential. Although the dam has not undergone any modifications in recent years, an emergency action plan (EAP) was last revised in 2017. The dam's risk assessment, inundation maps, and risk management measures are yet to be fully documented.
Overall, the Port Townsend Paper Asb Pond serves as a crucial water resource in the region, contributing to water storage and management efforts. With its significant hazard potential, it is essential for stakeholders to prioritize safety measures and regularly update the emergency action plan to mitigate risks associated with the dam's operation. For water resource and climate enthusiasts, monitoring the condition and management of this dam provides valuable insights into sustainable water infrastructure practices in Washington state.

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 Port Townsend Paper Asb Pond
Where does the data for Port Townsend Paper Asb Pond 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.
