Summary
This earth dam structure, designed by USDA NRCS in 1995, serves multiple purposes including fire protection, stock watering, and small fish pond management. With a maximum storage capacity of 69 acre-feet and a normal storage of 22 acre-feet, the dam covers a surface area of 4.1 acres and drains an area of 0.22 square miles.
The dam has a height of 28 feet and a length of 396 feet, providing flood risk reduction for the surrounding area. Despite its low hazard potential, the dam's condition assessment is currently not rated. It features an uncontrolled spillway type and is situated along the TR- Locust Creek, serving as a critical infrastructure for water management in the region. With no associated structures and a moderate risk assessment score, the site plays a crucial role in water resource conservation and climate resilience efforts in the Upper Locust Creek watershed.
While the dam has not been inspected recently and lacks an emergency action plan, its moderate risk level underscores the importance of regular maintenance and monitoring. As a key component of the local water infrastructure, the Upper Locust Creek Watershed Site L-19 contributes to the overall management of water resources in the area, emphasizing the need for continued regulatory oversight and maintenance to ensure its effectiveness in mitigating flood risks and supporting various water-related activities.

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.
