Canistear Reservoir #1 Dam dam
Canistear Reservoir #1 Dam
Located in Hardyston Township, New Jersey, the Canistear Reservoir #1 Dam stands as a testament to engineering ingenuity and environmental stewardship. Built in 1896, this earth dam serves as a crucial water supply source, with a storage capacity of 7,400 acre-feet and a surface area of 302 acres. The dam is situated along Peacock Brook and is regulated by the New Jersey Department of Environmental Protection, ensuring proper inspection, permitting, and enforcement measures are in place to maintain its structural integrity.
Standing at a height of 70 feet and spanning 680 feet in length, the Canistear Reservoir #1 Dam plays a vital role in flood control and water management in Sussex County. With a fair condition assessment and a high hazard potential, the dam undergoes regular inspections to ensure the safety of nearby communities. Despite its age, the dam continues to serve its primary purpose effectively, highlighting the importance of sustainable water resource management in the face of changing climate patterns.
As climate change continues to impact water resources worldwide, the Canistear Reservoir #1 Dam serves as a symbol of resilience and adaptability. With a strong foundation and a history of successful water supply management, this historic structure stands as a beacon of hope for future generations of water resource and climate enthusiasts. Its strategic location, efficient design, and regulatory oversight make it a shining example of how infrastructure can work in harmony with nature for the benefit of all.

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 Canistear Reservoir #1 Dam
Where does the data for Canistear Reservoir #1 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.
