Summary
This earth dam, completed in 1954, stands at a height of 28 feet and spans 500 feet in length. With a normal storage capacity of 70 acre-feet and a maximum discharge of 108 cubic feet per second, the dam plays a crucial role in managing water resources in the area.
The dam's spillway, of uncontrolled type and 15 feet wide, ensures proper water flow during periods of excess precipitation. Despite an undetermined hazard potential, the dam is subject to regular inspections, with the last one conducted in July 2019. The risk assessment for Whitfield Pond Dam 2 indicates a moderate risk level, emphasizing the importance of ongoing monitoring and potentially implementing risk management measures to ensure the safety and efficiency of the structure.
Water resource and climate enthusiasts will find Whitfield Pond Dam 2 an intriguing case study in dam infrastructure management. Its connection to Adams Creek W river/stream and its impact on the surrounding environment make it a fascinating subject for those interested in the intersection of water management, climate resilience, and regulatory oversight. The dam's role in flood control, water storage, and potential emergency response situations underscores the critical importance of maintaining and monitoring such structures for the well-being of both people and ecosystems.

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.
