Summary

This earth dam stands at a remarkable height of 79 feet, with a storage capacity of 770 acre-feet. While the dam's primary purpose is listed as 'Other', its construction and regulatory oversight fall under the jurisdiction of the Mine Safety and Health Administration. Despite its undetermined hazard potential and lack of condition assessment rating, this dam serves as a significant structure for water resource management in the area.

The dam, owned by unspecified entities and not regulated by the state, poses an interesting case for water resource and climate enthusiasts. With no recent inspection or assessment data available, the risk associated with Star Branch Dam #1 remains uncertain. Its proximity to the Huntington District and the oversight by the Mine Safety and Health Administration raise questions about its long-term sustainability and safety measures. The lack of detailed information about its design and construction adds to the mystery surrounding this crucial water management infrastructure.

For those passionate about water resource management and climate resilience, Star Branch Dam #1 presents a unique case study in the world of dam infrastructure. With its significant height and storage capacity, the dam plays a vital role in the local ecosystem. However, the absence of recent inspection data, condition assessment, and risk evaluation leave room for further investigation and monitoring. Understanding the complexities of this dam's operation and maintenance is essential for ensuring the safety and sustainability of water resources in Buchanan, Virginia, and beyond.

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.
