Summary
Constructed in 1967 by the USDA NRCS, this earth dam stands at a height of 45.2 feet and has a maximum storage capacity of 131.6 acre-feet. With a hazard potential rated as "High" and a condition assessment deemed "Satisfactory" as of April 2013, this dam plays a crucial role in protecting the surrounding area from potential flooding events.
Managed by the local government and regulated by the West Virginia Division of Water and Waste Management, Polk Creek No.5 serves as a vital infrastructure for flood risk management in the region. Despite its moderate risk assessment rating of 3, the dam has demonstrated its effectiveness in safeguarding the community against potential inundation. With its uncontrolled spillway type and outlet gates, this structure is equipped to handle maximum discharge rates and ensure the safety of residents in the event of heavy rainfall or flooding.
As a part of the Huntington District and under the jurisdiction of the state of West Virginia, Polk Creek No.5 is a significant water resource management asset that showcases the collaborative efforts between federal and local agencies in mitigating flood risks and protecting the environment. With its satisfactory condition, high hazard potential, and moderate risk assessment, this dam stands as a testament to the importance of proactive infrastructure development in the face of climate challenges.

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.
