Summary

This private earth dam, built on Punsit Creek, serves a vital purpose in regulating water flow and providing a storage capacity of 78 acre-feet. With a maximum discharge capability of 43 cubic feet per second and a spillway width of 20 feet, the dam ensures the safety and stability of the surrounding area, boasting a low hazard potential and a moderate risk assessment rating.

Managed by the New York State Department of Environmental Conservation (NYS DEC), Lloyd Goodrich Pond Dam undergoes regular inspections to ensure its structural integrity and adherence to state regulatory standards. While the dam's condition is currently not rated, its design and construction reflect a commitment to environmental protection and flood control. With a drainage area of 0.05 square miles and a surface area of 4 acres, the dam plays a crucial role in mitigating potential risks and maintaining water quality in the region.

As climate change continues to impact water resources, Lloyd Goodrich Pond Dam remains a beacon of resilience and sustainability. With a primary purpose of "other" and a primary dam type of earth, this essential infrastructure provides a vital link between conservation efforts and community safety. Supported by federal and state agencies, this dam serves as a model for effective water management practices and underscores the importance of proactive measures in safeguarding our natural environment for future generations.

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.
