Summary

The dam has a storage capacity of 384.9 acre-feet and serves various purposes, although the primary purpose is not specified in the data. Despite being in the Baltimore District, the dam is not regulated by the state and lacks inspection, permitting, and enforcement protocols.

The condition of Fannon Dam is currently not rated, and its hazard potential is listed as undetermined. Emergency action plans, risk assessments, and management measures are also not documented for this structure. The dam's risk profile and inundation maps are yet to be prepared or updated, raising concerns about its safety and emergency preparedness in the face of potential climate events or water resource challenges.

With its location in Virginia and under private ownership, Fannon Dam presents an interesting case for water resource and climate enthusiasts to explore. The lack of regulatory oversight and comprehensive risk assessment highlight the importance of ensuring the safety and resilience of such critical infrastructure in the face of a changing climate and increasing water resource demands. Further research and attention to Fannon Dam could provide valuable insights into the management and governance of similar structures across the region.

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.
