Summary
Built in 1971, this earth dam stands at a height of 15 feet and has a hydraulic height of 11 feet. With a storage capacity of 630 acre-feet and a maximum discharge of 960 cubic feet per second, this dam on Field Bayou provides crucial water resources for the surrounding area.
Despite being privately owned and not regulated by the state, Moore Lake Dam has a low hazard potential and has not been rated for its condition. The dam has not been inspected recently, and emergency action plans and risk assessments have not been completed. While the dam's primary purpose is irrigation, it also offers recreational benefits to the community. With its strategic location and significant water storage capacity, Moore Lake Dam is a vital asset for water resource and climate enthusiasts in the area.
Though lacking in recent inspections and assessments, Moore Lake Dam remains a key structure for water management in Lafayette County. Its construction in 1971 has provided essential irrigation resources for the region, and its recreational opportunities add to its value. As water resource and climate enthusiasts continue to monitor and advocate for the maintenance and safety of Moore Lake Dam, its importance as a water management asset in Arkansas cannot be understated.

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.
