Hagerstown City Park Lake (Key Street) dam
Hagerstown City Park Lake (Key Street)
Hagerstown City Park Lake (Key Street) is a picturesque masonry dam located in Washington, Maryland, with a primary purpose of recreation. Completed in 1920, this dam stands at a height of 10 feet and spans 450 feet in length, creating a surface area of 5.2 acres and a maximum storage capacity of 60 acre-feet. The lake is fed by the Antietam Creek-TR and is regulated by the Maryland Dam Safety agency, ensuring its safety and compliance with state regulations.
With a low hazard potential and a satisfactory condition assessment, Hagerstown City Park Lake is a popular spot for outdoor enthusiasts to enjoy various recreational activities. The dam has a spillway type of "Uncontrolled" with a width of 6 feet, providing a safe outlet for excess water during heavy rainfall events. Despite its moderate risk assessment level of 3, the lake remains a beloved destination for locals and visitors alike, offering a serene setting for fishing, boating, and enjoying the natural beauty of the surrounding area. As a key feature in the city park, this dam serves as both a functional structure and a scenic backdrop for outdoor enjoyment.
Dam data reference
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 Hagerstown City Park Lake (Key Street)
Where does the data for Hagerstown City Park Lake (Key Street) 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.
