Concord Pond Dam dam
Concord Pond Dam
Concord Pond Dam, located in Cherry Tree Landing, Sussex, Delaware, is a state-regulated structure with a primary purpose of serving as a Fish and Wildlife Pond. The dam, standing at a height of 14.31 feet and spanning a length of 565 feet, has a storage capacity of 1481 acre-feet and a normal storage level of 1103.63 acre-feet. It is situated on the Deep Creek, within the Philadelphia District, and is overseen by the Delaware Department of Natural Resources and Environmental Control (DNREC).
The dam, classified as a Gravity type structure with Earth and Gravity components, features a Controlled spillway with a width of 95 feet and is equipped with 6 Slide (sluice gate) and 2 Vertical Lift outlet gates. With a Hazard Potential rating of High and a Condition Assessment of Fair, Concord Pond Dam has undergone modifications in 1978 and 2017 to enhance its hydraulic capabilities. The risk assessment for this dam is very high, highlighting the importance of ongoing monitoring and maintenance to ensure public safety and the integrity of the structure.
As a pivotal component in the management of water resources and wildlife habitats, Concord Pond Dam serves as a vital asset for the region. Its strategic location and function underscore the significance of proper regulatory oversight, regular inspections, and emergency preparedness to mitigate potential risks and safeguard the surrounding environment. Enthusiasts interested in water resource conservation and climate resilience will find Concord Pond Dam to be an intriguing case study in balancing ecological priorities with infrastructure management 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.

About Concord Pond Dam
Where does the data for Concord Pond 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 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.
