Summary
This earth dam, standing at 31 feet high with a length of 417 feet, plays a crucial role in safeguarding the surrounding area from potential flooding events. With a storage capacity of 89 acre-feet and a drainage area of 230.4 square miles, this dam on the TR-Little East Locust Creek is a key component in managing water resources in the region.
The dam's spillway, measuring 32 feet wide, is of the uncontrolled type, ensuring efficient water discharge during high flow events. Despite being classified as having a low hazard potential and a moderate risk level, the dam's condition is currently not rated. While there are no outlet gates or associated structures, the East Locust Creek Watershed Dam E-128 stands as a testament to the collaborative efforts of the local government and the Natural Resources Conservation Service in mitigating flood risks and protecting the community of Browning. Enthusiasts of water resource management and climate resilience will find this structure to be a fascinating example of sustainable infrastructure in the face of changing environmental conditions.

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.
