Glenmar Pond 2 Dam dam
Glenmar Pond 2 Dam
Glenmar Pond 2 Dam, located in Howard County, Maryland, was completed in 1984 and serves as a crucial structure for flood risk reduction along the Deep Run-TR river system. Designed by Boender Associates, Inc., this earth dam stands at a height of 3.2 meters and is regulated by the Maryland Dam Safety authority. With a significant hazard potential, the dam is inspected every three years and was last assessed as being in satisfactory condition in April 2021.
Owned by the local government, Glenmar Pond 2 Dam plays a vital role in protecting the surrounding community from potential flooding events. Despite its age, the dam has been well-maintained and meets regulatory guidelines set by the state. With no associated structures and a primary purpose of flood risk reduction, this dam stands as a testament to effective infrastructure management and the importance of water resource management in mitigating natural disasters.
For water resource and climate enthusiasts, Glenmar Pond 2 Dam represents a key piece of infrastructure in Maryland's flood risk reduction strategy. Its location in the Baltimore District and its association with the Deep Run-TR river highlight the interconnectedness of water resources and the need for proactive measures to address potential hazards. As efforts continue to ensure the dam's safety and effectiveness, it stands as a symbol of resilience in the face of environmental challenges.

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 Glenmar Pond 2 Dam
Where does the data for Glenmar Pond 2 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 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.
