Summary

This earth dam, with a height of 68 feet and a length of 1000 feet, provides storage capacity of up to 193,000 acre-feet. It is located on the Prescott River and covers a surface area of 2300 acres, with a drainage area of 5.4 square miles.

Despite being classified as having a low hazard potential, the dam has not been rated for its condition assessment. The last inspection date was in November 2002, with an inspection frequency of every 4 years. The dam is equipped with outlet gates and has a maximum storage capacity of 193,000 acre-feet. It is crucial for water supply purposes and is regulated by the New Jersey Department of Environmental Protection (NJDEP) to ensure its safety and integrity.

The Round Valley P&F Dike plays a vital role in water resource management in Hunterdon County, New Jersey. As a state-regulated structure, it undergoes regular inspections and is monitored for any potential risks or hazards. Its strategic location and design contribute to its effectiveness in providing water storage and supply for the surrounding area, highlighting the importance of proper management and maintenance of critical infrastructure for water resources and climate enthusiasts.

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. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
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. Investigations and studies are necessary.
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.
Not Available
Dams for which the condition assessment is restricted to approved government users.

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, environment 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.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
