Summary
The dam, with a height of 21 feet and a hydraulic height of 18 feet, offers a maximum storage capacity of 102 acre-feet and a normal storage of 72 acre-feet. The dam sits on Magness Creek-TR, providing a serene backdrop for outdoor activities such as fishing, boating, and picnicking.
Despite being privately owned and not regulated by the state, Omni Lake No 2 Dam has a low hazard potential and has not been rated for its condition assessment. The dam spans 628 feet in length and has a maximum discharge capacity of 1248 cubic feet per second. Although lacking in certain infrastructure like spillways and outlet gates, the dam remains a popular destination for locals and visitors alike to enjoy the beauty of the surrounding landscape and engage in various water-based activities. While the dam may not be extensively monitored or inspected, its presence adds to the recreational appeal of the Ward area in Arkansas, making it a valuable asset for the community.

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.
