Summary
The dam has a hydraulic height of 10 feet and a structural height of 10 feet, with a length of 700 feet. It has a normal storage capacity of 105 acre-feet and a maximum storage capacity of 175 acre-feet, serving as a vital water resource for the surrounding area.
Situated on Bayou Two Prairie-Os, Parker Lake Dam has a surface area of 29.9 acres and a drainage area of 0.78 square miles. Despite its low hazard potential and current condition being not rated, the dam plays a crucial role in water management and agriculture in the region. With its strategic location in the Vicksburg District and under the ownership of private entities, Parker Lake Dam contributes to the sustainability of water resources and irrigation practices in the area.
As a key infrastructure for water management, Parker Lake Dam serves as a testament to the importance of maintaining and monitoring dams for climate and water resource enthusiasts. Its history, design, and purpose underscore the critical role that such structures play in ensuring efficient water distribution and storage for agricultural and environmental needs 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.
