Lake Stockwell Dam dam
Lake Stockwell Dam
Lake Stockwell Dam, located in Medford Lakes, New Jersey, is a privately-owned earth dam that was completed in 1926 for recreational purposes. The dam, with a height of 12 feet and a length of 260 feet, impounds the Sharps Branch of Haynes Creek, creating a reservoir with a storage capacity of 176 acre-feet. The dam has a surface area of 23 acres and drains a watershed area of 5 square miles.
The dam is regulated by the New Jersey Department of Environmental Protection and is inspected regularly to ensure its safety. Despite being classified as having a significant hazard potential, the dam was found to be in satisfactory condition during its last assessment in October 2020. Emergency action plans are in place, although the details of their preparedness and adherence to guidelines are not specified in the available data. The dam's spillway type, width, and other structural details are not provided, but its maximum discharge capacity is noted as 515 cubic feet per second.
Overall, Lake Stockwell Dam serves as an important recreational resource in Burlington County, New Jersey, while also playing a crucial role in water management and flood prevention in the region. With its rich history, scenic location, and significant storage capacity, the dam continues to be a focal point for water resource and climate enthusiasts interested in the intersection of infrastructure, recreation, and environmental stewardship.

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 Lake Stockwell Dam
Where does the data for Lake Stockwell 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.
