New Bald Eagle Road Swm dam
New Bald Eagle Road Swm
New Bald Eagle Road Swm, located in Prince George's County, Maryland, is a state-regulated flood risk reduction structure designed by KCI Technologies. Completed in 2006, this earth dam stands at a height of 43.5 feet and has a hydraulic height of 15 feet, with a primary purpose of flood risk reduction along the Oxon Creek-TR. The dam has a storage capacity of 18.6 acre-feet and a normal storage volume of 1.28 acre-feet, serving a drainage area of 0.12 square miles.
Despite its critical role in flood risk reduction, New Bald Eagle Road Swm has been assessed as being in poor condition with a high hazard potential. The last inspection in December 2021 revealed its poor condition, and it has been deemed to have a moderate risk level. The emergency action plan for the dam was last revised in May 2021, but further improvements and risk management measures may be necessary to address the existing hazards and ensure the safety and resilience of the structure.
With its location in Forest Heights and its vital function in mitigating flood risks in the area, New Bald Eagle Road Swm is a significant asset that requires ongoing maintenance and monitoring to safeguard the community and surrounding environment. As water resource and climate enthusiasts, it is crucial to stay informed about the condition of such infrastructure and advocate for necessary improvements to enhance resilience and ensure the long-term sustainability of our water resources.

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 New Bald Eagle Road Swm
Where does the data for New Bald Eagle Road Swm 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.
