Serenity Lake Dam dam
Serenity Lake Dam
Serenity Lake Dam, also known as Jumpoff Jim Lake Dam, is a privately owned structure located in Valley, Washington. Completed in 1972, this earth dam stands at 17 feet high with a hydraulic height of 17 feet and a structural height of 12 feet. The dam serves primarily for recreational purposes, providing a storage capacity of 270 acre-feet and covering a surface area of 61 acres. Situated on the Tr-Colville River, it plays a vital role in managing the water resources in Stevens County.
Despite its fair condition assessment in 2016, Serenity Lake Dam is classified with a high hazard potential due to its location and the volume of water it holds. The dam is regulated by the Washington Department of Ecology, ensuring that it undergoes regular inspections and meets safety standards. The surrounding area is at risk of inundation in the event of a breach, highlighting the importance of emergency preparedness and risk management measures for this critical infrastructure.
With its picturesque location and significant role in providing recreational opportunities and regulating water flow, Serenity Lake Dam is a notable feature in the landscape of Washington. Climate and water resource enthusiasts can appreciate the engineering and environmental considerations that go into maintaining and managing this essential structure to ensure the safety and well-being of the surrounding community and ecosystem.
Dam data reference
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 Serenity Lake Dam
Where does the data for Serenity Lake 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 High 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.
