Summary
Completed in 1973, this private earth dam stands at a height of 25 feet and has a storage capacity of 67 acre-feet. While it primarily functions to mitigate flood risks, it also supports fire protection, stock, or small fish pond maintenance, as well as recreational activities for the community.
With a low hazard potential and a moderate risk assessment rating, Hollingsworth Lake Dam is a reliable infrastructure that contributes to the overall safety and well-being of the region. Although not regulated by the state, this dam plays a significant role in managing water resources and ensuring the protection of surrounding areas. Despite its uncontrolled spillway type, the dam has not experienced any significant modifications since its completion, highlighting its stability and effectiveness in flood risk reduction efforts.
Located in a picturesque setting near TR to Little Sni-A-Bar Creek, Hollingsworth Lake Dam stands as a testament to the importance of sustainable water management practices in the face of changing climate patterns. As enthusiasts of water resources and climate resilience, the significance of this dam goes beyond its physical structure, serving as a reminder of the vital role that such infrastructure plays in safeguarding communities and ecosystems against the impacts of extreme weather events.

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.
