Wyndemere Swm Pond dam
Wyndemere Swm Pond
Wyndemere Swm Pond, also known as Old Scaggsville Road, is a privately owned water resource in Howard County, Maryland. Constructed in 1995 by TSA Group & E2Si, this earth-type dam serves primarily for flood risk reduction along the Patuxent River-TR. Standing at a height of 13.2 feet and stretching 380 feet in length, it has a storage capacity of 8 acre-feet and a maximum discharge rate of 1443 cubic feet per second.
Managed by the Maryland Dam Safety agency, Wyndemere Swm Pond has a significant hazard potential but has been assessed to be in satisfactory condition as of June 2018. The dam is subject to regular inspections, with the last one conducted in May 2019, and has an established Emergency Action Plan to ensure preparedness in case of any emergencies. Its risk assessment is rated as moderate, reflecting the potential risks associated with its location and design.
Water resource and climate enthusiasts will find Wyndemere Swm Pond an intriguing case study for flood risk reduction infrastructure in Maryland. With its unique design features, regulatory oversight by the state, and management practices, this dam stands as a testament to the importance of maintaining and monitoring critical water resources to ensure the safety and well-being of surrounding communities.

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.
Plan around the weather
Same NOAA / yr.no feed Snoflo's iOS app uses. Watch the precipitation column on the meteogram -- rain on the basin upstream typically lifts inflow 24-72 hours later.

About Wyndemere Swm Pond
Where does the data for Wyndemere Swm Pond 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 Significant 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.
