Willow Crest Dam dam
Willow Crest Dam
Willow Crest Dam, located in Stillwater Township, New Jersey, is a state-owned earth dam constructed in 1965 on the Black Brook river. With a height of 17 feet and a length of 400 feet, the dam serves primarily for recreational purposes, providing a surface area of 28 acres and a maximum storage capacity of 351 acre-feet. The dam has a high hazard potential but is currently in satisfactory condition, as per the last inspection conducted in August 2021.
Managed by the New Jersey Department of Environmental Protection (NJDEP), Willow Crest Dam is regularly inspected and regulated to ensure its safety and compliance with state standards. The dam is situated in a scenic area in Sussex County, offering opportunities for outdoor activities such as boating, fishing, and hiking. Despite its age, the dam continues to provide essential water resource management and recreational benefits to the local community, demonstrating the importance of proper maintenance and oversight of critical infrastructure in the face of climate variability and change.
As climate enthusiasts and water resource advocates, it is crucial to recognize the role of structures like Willow Crest Dam in balancing water supply, flood control, and recreational needs in a changing climate. By staying informed about the condition and management of dams like Willow Crest, we can contribute to sustainable water resource practices and help protect our communities from the impacts of extreme weather events and water scarcity.

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 Willow Crest Dam
Where does the data for Willow Crest 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.
