Summary

Completed in 1988, this earth-type dam stretches 450 feet in length and reaches a height of 11.5 feet, with a storage capacity of 23 acre-feet. The dam is owned and regulated by local government authorities and falls under the jurisdiction of the New Jersey Department of Environmental Protection.

Despite its significant hazard potential, Hoaglan Farms West Dam has been assessed as being in satisfactory condition as of December 2019. Regular inspections ensure its operational integrity and readiness to mitigate flood risks in the Somerset County area. The dam's primary purpose is to safeguard the surrounding community from potential inundation, with a normal storage capacity of 10 acre-feet and a maximum discharge capability of 793 cubic feet per second.

Water resource and climate enthusiasts can appreciate the vital role that Hoaglan Farms West Dam plays in protecting the local environment and infrastructure from flooding events. Its strategic location and design demonstrate a commitment to sustainable water management practices and the preservation of natural resources in the region. As a key element of flood risk reduction efforts, this dam serves as a testament to the collaborative efforts of local government agencies in ensuring the safety and resilience of communities in New Jersey's waterways.

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.
