Summary
Standing at a height of 13.25 feet and with a storage capacity of 156.46 acre-feet, this dam plays a crucial role in water resource management in the region. While its primary purpose is not specified in the data, the dam's normal storage capacity of 28.78 acre-feet indicates its importance in maintaining water supply and regulating flow.
Despite being categorized as having an "Undetermined" hazard potential and a "Not Rated" condition assessment, Clowser Dam undergoes regular inspections and is subject to state enforcement and permitting. This suggests a proactive approach to ensuring the safety and functionality of the structure. With a latitude of 39.1555 and longitude of -78.0683, the dam's strategic location further highlights its significance in the water management infrastructure of the area. For water resource and climate enthusiasts, Clowser Dam serves as a unique point of interest due to its structural characteristics and regulatory framework.
As part of the Baltimore District, Clowser Dam is a key component of the water management system in Clarke, Virginia. While the specific year of completion and primary purpose are not provided, the dam's impressive dimensions and storage capacity underscore its importance in the region's water resource management. With ongoing inspections and state regulation in place, Clowser Dam stands as a testament to the efforts to ensure the safety and functionality of critical water infrastructure in the area. For enthusiasts interested in water resources and climate resilience, this privately owned dam offers a fascinating case study in dam management and regulatory oversight.

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.
