Summary
Constructed in 1988 by the USDA NRCS, this earth dam stands at a height of 27 feet and spans 570 feet in length. With a storage capacity of 89 acre-feet and a drainage area of 147.2 square miles, this dam plays a crucial role in mitigating flood risks in the area.
Situated in the Rock Island District, this dam on the TR-East Locust Creek is designed to handle a maximum discharge of 192 cubic feet per second. Despite its low hazard potential, the dam is classified as having a moderate risk level, indicating the need for continued monitoring and risk management measures. While currently in "Not Rated" condition, regular inspections and assessments are essential to ensure the dam's structural integrity and effectiveness in flood control.
Although the dam does not have a state jurisdiction or permitting requirements, its primary purpose remains flood risk reduction. With no associated structures or outlet gates, the dam relies on an uncontrolled spillway with a width of 32 feet. As climate change continues to impact water resources, structures like East Locust Creek Watershed Dam E-83 are essential for safeguarding communities and infrastructure from the increasing threat of floods.

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.
