Summary
This earth dam stands at a height of 22 feet and has a length of 700 feet, creating a reservoir with a normal storage capacity of 72 acre-feet. The dam is situated on Hines Branch-TR, within the jurisdiction of the Vicksburg District of the US Army Corps of Engineers.
With a low hazard potential and a condition assessment of "Not Rated", Harris Lake Dam plays a crucial role in providing water resources for various purposes including recreation. Although not regulated by the state, the dam ensures the safety and water supply for the surrounding area. The dam also offers a surface area of 4.3 acres and a maximum discharge capacity of 129 cubic feet per second.
Water resource and climate enthusiasts will appreciate Harris Lake Dam for its contribution to the local ecosystem and water management practices. As a private-owned structure, the dam represents a vital infrastructure for maintaining water levels, supporting wildlife habitats, and serving as a recreational spot for the community. The history and design of Harris Lake Dam showcase the importance of sustainable water resource management in Arkansas, highlighting the intersection of human development and environmental conservation.

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.
