Pohick Creek Dam #8 dam
Pohick Creek Dam #8
Pohick Creek Dam #8, also known as Lake Huntsman, is owned by the local government in Fairfax, Virginia. This earth dam on Middle Run serves the primary purpose of flood risk reduction, with a height of 45.4 feet and a storage capacity of 1740 acre-feet. The dam, with a length of 700 feet, plays a crucial role in protecting the surrounding area from potential flooding events.
Located in the Baltimore District, Pohick Creek Dam #8 is regulated by the Department of Conservation and Recreation in Virginia. Despite being classified with a high hazard potential, the dam's condition assessment in October 2020 reported it as satisfactory. Regular inspections ensure its safety and functionality, with an inspection frequency of one year. The dam's emergency action plan was last revised in March 2014, indicating proactive measures in place for potential emergencies.
With its significant role in flood risk reduction and the protection of the local community, Pohick Creek Dam #8 stands as a vital infrastructure in Fairfax County, Virginia. Its strategic location, design, and maintenance highlight the importance of water resource management and climate resilience in safeguarding communities from natural disasters. As water resource and climate enthusiasts, understanding and appreciating the role of dams like Pohick Creek Dam #8 is crucial in promoting sustainable practices for a safer and more resilient future.

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 Pohick Creek Dam #8
Where does the data for Pohick Creek Dam #8 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.
