Summary
Completed in 1962, this earth dam stands at a hydraulic height of 20 feet and a structural height of 25 feet, with a length of 260 feet. The dam has a maximum storage capacity of 62 acre-feet and normal storage of 32 acre-feet, serving as a crucial resource for water management in the region.
Despite being classified with a low hazard potential and a moderate risk assessment, Barr Lake Dam has not been fully rated for its condition and emergency preparedness. The dam features an uncontrolled spillway type and a maximum discharge capacity of 1035 cubic feet per second. While the structure has not been inspected recently and lacks an Emergency Action Plan (EAP), it remains a key component in the local water infrastructure for fire protection and livestock maintenance. With its strategic location on Ten Mile Creek in Saline County, Barr Lake Dam represents a vital asset for water resource and climate enthusiasts interested in the management of small-scale water bodies in Arkansas.

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.
