Summary
Built in 1960, this Earth dam stands at a hydraulic height of 19.9 feet and a structural height of 25.9 feet, with a total length of 470 feet. The dam has a storage capacity of 300 acre-feet and covers a surface area of 11 acres, serving as a modest but essential water resource for the region.
Despite its low hazard potential, Lost Acres is considered to have a moderate risk level, with a risk assessment rating of 3. The dam has not been rated for its condition assessment and lacks an Emergency Action Plan (EAP). However, it has undergone regular inspections, with the last one conducted in January 2017. With no associated structures and no federal oversight, Lost Acres remains a local asset for water storage and management in the area.
Water resource and climate enthusiasts will find Lost Acres an intriguing structure in the landscape of Maury, Tennessee. With its historical significance dating back to the 1960s, this Earth dam continues to provide essential water storage for the community along Snow Creek. While it may have a moderate risk level, the dam's low hazard potential and regular inspections ensure its continued functionality for the region's water management needs.

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.
