Summary
The dam, built for an undisclosed primary purpose, serves to regulate water levels and provide irrigation for the surrounding area. With a normal storage capacity of 184 acre-feet and a surface area of 92 acres, this dam plays a crucial role in managing water resources in the region.
Despite its importance, Legette Millpond Dam currently has an undetermined hazard potential and is not rated for its condition assessment. The dam's emergency action plan (EAP) status, risk assessment, and management measures are also not specified. As an unregulated structure with no state jurisdiction or permitting, the dam's safety and maintenance responsibilities may fall on the owner or local authorities. Further evaluation and risk mitigation measures may be necessary to ensure the long-term safety and stability of this essential water resource infrastructure.
Enthusiasts of water resources and climate monitoring should take note of Legette Millpond Dam's significance in the region and its potential risks. With its location in a critical watershed area, the dam's condition and maintenance should be closely monitored to prevent any potential hazards or failures. Collaboration between local authorities, owners, and regulatory agencies may be necessary to ensure the continued functionality and safety of this important water resource structure for the surrounding community and ecosystem.

Dam Data Reference
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.
