Merrill Creek Northwest Dike 1 dam
Merrill Creek Northwest Dike 1
Merrill Creek Northwest Dike 1 is a crucial water resource structure located in Warren, New Jersey, along the Merrill Creek river. This private-owned earth dam stands at a height of 20 feet and spans 800 feet in length, providing a storage capacity of 46,000 acre-feet. With a surface area of 690 acres and a drainage area of 2 square miles, this dike plays a pivotal role in managing water flow and storage in the region.
Managed by the New Jersey Department of Environmental Protection (NJDEP), Merrill Creek Northwest Dike 1 is regulated, permitted, inspected, and enforced by the state authorities to ensure its structural integrity and safety. Despite its high hazard potential, the dam's condition assessment remains satisfactory, with the last inspection conducted in June 2021. In case of emergencies, an Emergency Action Plan (EAP) is in place, although details on its preparation and compliance with guidelines are yet to be updated.
For water resource and climate enthusiasts, Merrill Creek Northwest Dike 1 serves as a critical infrastructure for water management and flood control in the Harmony Township area. With its significant storage capacity and state-regulated maintenance, this earth dam plays a vital role in safeguarding the surrounding communities and environment from potential risks. As a part of the larger water resource system in New Jersey, this dike stands as a testament to efficient water infrastructure management and regulatory oversight in the region.
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 Merrill Creek Northwest Dike 1
Where does the data for Merrill Creek Northwest Dike 1 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.
