Summary
Designed by the USDA NRCS and completed in 2010, this earth dam stands at a height of 27.7 feet and has a structural height of 31 feet, with a length of 440 feet. It serves the primary purpose of flood risk reduction and is associated with the TR-ROOKS BRANCH river or stream.
With a normal storage capacity of 45.5 acre-feet and a maximum storage of 153.6 acre-feet, Upper Locust Creek R- 14 plays a crucial role in managing water resources in the area. The dam has a low hazard potential and is currently rated as "Not Rated" in terms of its condition assessment. While it does not have a state regulatory agency overseeing it, the structure meets moderate risk management guidelines, indicating its importance in mitigating potential flooding impacts.
The dam's uncontrolled spillway, with a width of 40 feet, can handle a maximum discharge of 257.2 cubic feet per second, serving as a vital mechanism for flood control. Despite not having outlet gates, Upper Locust Creek R- 14 continues to contribute to the overall protection of the surrounding area from flooding events. Its presence highlights the collaborative efforts of local government and the Natural Resources Conservation Service in safeguarding communities against water-related challenges.

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.
