Summary
This earth dam, with a height of 26 feet and a hydraulic height of 24 feet, serves primarily for irrigation purposes. The dam has a storage capacity of 980 acre-feet, with a normal storage level of 720 acre-feet. The pond created by the dam covers a surface area of 90 acres and has a drainage area of 5.8 square miles, making it a significant water resource for the surrounding region.
Managed by the Department of Conservation and Recreation in Massachusetts, the Tihonet Pond #2 Dam is classified as a significant hazard potential structure with a satisfactory condition assessment as of the last inspection in October 2015. Despite its moderate risk level, the dam has met regulatory guidelines and inspection requirements set forth by the state. Given its critical role in irrigation and water resource management, the dam's structural integrity and maintenance are crucial for ensuring the safety and reliability of the surrounding water supply. Enthusiasts interested in water resources and climate change will find Tihonet Pond #2 Dam a compelling case study for understanding the intersection of infrastructure, environmental conservation, and risk management in the face of changing climate patterns.

Condition Assessment
SatisfactoryNo 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
HighDams 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.
