Summary
Completed in an unspecified year, this dam has a storage capacity of 400 acre-feet and a surface area of 11 acres. Despite being unlisted for specific purposes, the dam is primarily regulated and inspected by the state, with a low hazard potential and a moderate risk assessment rating.
Designed by Tribble and Richardson, Vinson Impound No.2 Dam features an uncontrolled spillway and outlet gates. The last inspection was conducted in October 2006, with a scheduled inspection frequency of every 5 years. Although the dam's condition assessment is currently "Not Rated," the risk management measures are in place to address any potential issues. With a state jurisdiction and enforcement in place, this dam serves as a vital structure in safeguarding water resources in the area.
As an enthusiast of water resources and climate, the Vinson Impound No.2 Dam presents an intriguing case study in dam engineering and management. With its unique design features and regulatory framework, this dam offers insights into the complexities of ensuring water security while balancing environmental risks. The moderate risk assessment and low hazard potential underscore the importance of ongoing monitoring and maintenance to uphold the dam's integrity and protect downstream communities from potential hazards.

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.
