Summary

Built in 1972, this earth dam stands at a height of 20 feet and has a storage capacity of 235 acre-feet. With a normal storage level of 147 acre-feet and covering a surface area of 22 acres, this dam plays a crucial role in supplying water for agricultural needs in the area.

Although not regulated by the state, Maple Lane Farms Lake Dam has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment. The dam is situated on the TR-DRY FORK river/stream and falls under the jurisdiction of the Little Rock District in terms of maintenance and oversight. Despite lacking certain inspection and emergency preparedness measures, the dam continues to serve its purpose effectively and efficiently for the community.

Water resource and climate enthusiasts will find Maple Lane Farms Lake Dam to be an interesting case study in private dam ownership and management. From its construction history to its current operational status, this dam offers insights into the importance of irrigation infrastructure in supporting agricultural activities in the region. With its modest size and storage capacity, Maple Lane Farms Lake Dam represents a valuable water resource asset that contributes to the local economy and ecosystem.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
