About this dam

New Germany State Park Dam

New Germany State Park Dam, also known as Swaugers Mill Dam, is a picturesque earth dam located in Garrett County, Maryland. Built in 1930 by the US WPA/CCC, this dam is primarily used for recreation purposes and stands at a height of 12 feet with a length of 164 feet. Situated on the Poplar Lick Run, the dam has a normal storage capacity of 52 acre-feet and a maximum discharge of 380 cubic feet per second.

Managed by the Maryland Dam Safety agency, the New Germany State Park Dam has undergone modifications in 2008 for both hydraulic and structural improvements. Despite its low hazard potential, the dam is regularly inspected with a satisfactory condition assessment as of April 2021. With its serene surroundings and ample recreational opportunities, this dam serves as a vital water resource for the community while also ensuring public safety and enjoyment.

For water resource and climate enthusiasts, the New Germany State Park Dam presents a unique blend of history, engineering, and environmental stewardship. From its humble origins as a CCC project to its modern-day management by the Maryland authorities, this dam exemplifies the importance of sustainable water infrastructure in balancing the needs of recreation, conservation, and safety. Whether exploring the surrounding trails or observing the uncontrolled spillway in action, visitors to this dam can appreciate the beauty and resilience of our natural water systems in the face of changing climate conditions.

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.

FAQ

About New Germany State Park Dam

Where does the data for New Germany State Park 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 Low 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.
