Summary
Built in 1999 by USDA NRCS, this dam stands at a height of 25 feet and serves the primary purpose of flood risk reduction along the TR-East Fork Locust river. With a maximum storage capacity of 45 acre-feet and a normal storage of 17 acre-feet, this dam covers a surface area of 4 acres and has a spillway width of 30 feet for uncontrolled water discharge.
Despite being rated as having a low hazard potential and moderate risk assessment, East Locust Creek E-41 has not been inspected since its completion in 1999. The dam has not been given a condition assessment and does not have an Emergency Action Plan (EAP) in place. However, with its stone core and soil foundation, the dam is designed to withstand hydraulic pressures and structural heights of up to 32 feet. Although no modifications have been reported, the dam's risk management measures and inundation maps are yet to be prepared, indicating a need for proactive monitoring and maintenance to ensure its continued effectiveness in flood risk reduction efforts.
East Locust Creek E-41, situated in an area represented by Congressman Sam Graves, plays a crucial role in protecting the surrounding community from flood events. As climate change continues to impact water resources and increase the frequency of extreme weather events, it is imperative for local government agencies to prioritize the inspection, maintenance, and risk management of dams like E-41 to safeguard lives and properties 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.
