Summary

Built in 1976 by the USDA NRCS, this earth dam stands at a height of 46 feet and stretches over 800 feet in length. With a primary purpose of flood risk reduction, it has a storage capacity of 910 acre-feet, serving to protect the surrounding area from potential flooding events.

Managed by the local government and regulated by the NYS DEC, Newtown Hoffman Site 1 Dam is inspected biennially to ensure its structural integrity and safety. It has a high hazard potential due to its location and design, but as of the last assessment in March 2019, it was deemed to be in satisfactory condition. In the event of an emergency, the dam has emergency action plans in place, although further updates and revisions may be necessary to meet current guidelines and ensure efficient risk management.

With a moderate risk assessment score of 3, Newtown Hoffman Site 1 Dam plays a crucial role in mitigating flood risks in the region. As water resource and climate enthusiasts, it is essential to monitor and support the ongoing maintenance and improvement efforts for this vital infrastructure to safeguard the community and environment from potential hazards and ensure sustainable water resource management in the area.

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.
