Summary
The dam is privately owned and stands at a height of 28 feet with a hydraulic height of 25 feet, making it an important asset for managing water resources in the region. With a normal storage capacity of 70 acre-feet and a maximum discharge of 700 cubic feet per second, the dam plays a vital role in regulating water levels and ensuring sustainable water supply for the surrounding area.
Managed by the Arkansas Natural Resources Commission, Horne Lake Dam is subject to regular state inspections, enforcement, and permitting to ensure its structural integrity and compliance with regulations. Despite being classified as having a low hazard potential, the dam's condition assessment is currently not rated, highlighting the need for ongoing monitoring and maintenance to ensure its long-term safety and effectiveness. The dam's location on Derrieusseaux Creek-TR adds to its significance in managing water resources and protecting against potential risks in the area.
In addition to its recreational and water supply purposes, Horne Lake Dam also serves as a critical infrastructure for the community, with a storage capacity of 100 acre-feet and a surface area of 12.8 acres. It is situated within the Little Rock District of the US Army Corps of Engineers and is a key component in the overall water management system of Grant County, Arkansas. Despite its low hazard potential, ongoing assessments and risk management measures are essential to ensure the dam's continued functionality and safety for both water resource and climate enthusiasts in the region.

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.
