Summary

The dam that creates the pond was completed in 1885 and stands at a height of 9 feet, with a maximum storage capacity of 255 acre-feet. With a surface area of 30 acres and a drainage area of 2 square miles, Tarbox Pond serves as a primary recreational destination for visitors seeking outdoor activities such as fishing, boating, and birdwatching.

Despite its historical significance and recreational value, Tarbox Pond is facing challenges in terms of its condition assessment, which was rated as poor during the most recent evaluation in May 2018. The dam's hazard potential is classified as low, but there is a need for improvement in its overall structural integrity to ensure the safety and sustainability of the pond for future generations. Climate enthusiasts and water resource advocates can engage in discussions and initiatives to address these issues, emphasizing the importance of maintaining and preserving this natural ecosystem.

As climate change continues to impact water resources and ecosystems, the conservation and management of Tarbox Pond become increasingly crucial. By raising awareness about the pond's condition and advocating for sustainable practices, enthusiasts can contribute to ensuring the long-term health and resilience of this scenic water body. Collaboration with local authorities and stakeholders is essential in implementing effective risk management measures and maintaining the ecological balance of Tarbox Pond for the benefit of both humans and wildlife.

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.
