Summary
This earth dam stands at a height of 17 feet and has a length of 600 feet, with a storage capacity of 165 acre-feet. Despite its undetermined hazard potential and unrated condition assessment, the dam is subject to state permitting, inspection, and enforcement by the Department of Conservation and Recreation.
Located within the Norfolk District of the US Army Corps of Engineers, Talley Millpond Dam is not federally owned or funded. It lacks detailed information on its construction year, spillway type, and other key features, suggesting a need for further assessment and risk management measures. While the dam does not currently have an Emergency Action Plan (EAP) in place, its inspection frequency is set at 1 year, indicating a proactive approach to ensuring the safety and integrity of this vital water resource infrastructure.
For water resource and climate enthusiasts, Talley Millpond Dam presents an intriguing case study in the management of a critical water supply structure. With its position in a state-regulated jurisdiction and the potential for hazard mitigation measures in the future, this dam invites further exploration into the intersection of infrastructure, environmental protection, and public safety in the face of changing climate conditions.

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.
