Summary
This earth dam stands at 28 feet tall and stretches 510 feet in length, with a storage capacity of 81 acre-feet to manage the flow of the TR-Little East Locust Creek. With a low hazard potential and a moderate risk assessment, this dam plays a vital role in protecting the surrounding area from potential flooding events.
Despite its importance in flood control, East Locust Creek Watershed Dam E-117 has not been rated for its condition assessment, and there are no inspection records available. The dam features an uncontrolled spillway with a width of 32 feet, allowing for the release of excess water during high flow periods. While the dam has not been modified since its completion, it serves as a key structure in the region's water resource management, with a normal storage capacity of 24 acre-feet and a maximum discharge of 190 cubic feet per second.
As a part of the Rock Island District, East Locust Creek Watershed Dam E-117 plays a crucial role in protecting the residents of Browning and the surrounding area from potential flood risks. With its strategic location and design by the Natural Resources Conservation Service, this dam stands as a testament to effective water resource management and climate resilience in the region.

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.
