Boman Reservoir Dam dam
Boman Reservoir Dam
Boman Reservoir Dam, located in Ferry County, Washington, was completed in 1977 for the primary purpose of irrigation. This earth dam stands at a hydraulic height of 23 feet and a structural height of 18 feet, with a length of 500 feet and a storage capacity of 104 acre-feet. The reservoir covers 7.3 surface acres and serves a drainage area of 0.45 square miles. Managed by a private owner, the dam is regulated by the Washington Department of Ecology, ensuring state jurisdiction, permitting, inspection, and enforcement.
Despite its fair condition assessment and high hazard potential, Boman Reservoir Dam has not undergone recent modifications or emergency action plan updates. The last inspection in August 2018 revealed a need for further risk assessment and management measures to address potential vulnerabilities. With a designated inspection frequency of 5 years, the dam's emergency preparedness and inundation mapping readiness remain unclear, highlighting the importance of proactive measures to safeguard the surrounding community and environment in case of a catastrophic event.
For water resource and climate enthusiasts, Boman Reservoir Dam offers a fascinating case study in dam infrastructure and management. The dam's role in supporting local irrigation needs underscores the critical balance between water resource utilization and safety considerations. As climate change impacts continue to influence water availability and infrastructure resilience, the ongoing monitoring and maintenance of Boman Reservoir Dam serve as a crucial example of the challenges and opportunities in sustainable water management practices in the Pacific Northwest region.

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 Boman Reservoir Dam
Where does the data for Boman Reservoir 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.
