Summary
This earth dam stands at a height of 27 feet and has a storage capacity of 140.3 acre-feet, with a normal storage level of 43.2 acre-feet. The dam serves multiple purposes, including fire protection, stock or small fish pond, fish and wildlife pond, and flood risk reduction.
With a drainage area of 1651 acres and a maximum discharge of 175.8 cubic feet per second, Upper Locust Creek L- 84 plays a crucial role in managing water flow in the TR-Locust Creek watershed. The dam is classified as having a low hazard potential and a moderate risk level. Despite not being rated for condition assessment, the structure is maintained by the Natural Resources Conservation Service to ensure its effectiveness in flood risk reduction and water resource management.
Managed by the Rock Island District of the USACE, Upper Locust Creek L- 84 is an integral part of the local government's efforts to protect the community from flooding and enhance water quality in the region. The dam's uncontrolled spillway and outlet gates help regulate water levels and prevent potential hazards. Overall, this structure exemplifies the importance of sustainable water resource management and climate resilience in the face of changing environmental conditions.

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.
