Summary
Standing at a height of 20 feet with a hydraulic height of 16 feet, this earth dam was completed in 1937 and has a storage capacity of 80 acre-feet. The dam, situated on Patterson Creek-TR, spans 360 feet in length and has a maximum discharge rate of 240 cubic feet per second.
Despite being categorized as having a low hazard potential, Crystal Lake Dam has not been rated for its condition. There is no state regulation or inspection in place for this dam, and it is not under the jurisdiction of any governmental agency. The dam has no associated structures and has not undergone any modifications in recent years. Emergency preparedness measures, such as an Emergency Action Plan (EAP), are also not documented for this dam.
Water resource and climate enthusiasts interested in Crystal Lake Dam will find it to be a modest yet intriguing structure with a focus on recreational purposes. The dam's historical significance, coupled with its location in Lee County, Arkansas, makes it a notable feature for those interested in exploring the intersection of water management and environmental conservation. While the lack of regulatory oversight may raise some concerns, the overall low hazard potential suggests that the dam is currently stable and poses minimal risk to surrounding areas.

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.
