Summary
This earth dam, standing at a height of 29 feet, serves to control water flow and prevent erosion in the area. With a normal storage capacity of 6 acre-feet and a maximum storage of 19 acre-feet, the dam plays a crucial role in managing water resources in the region.
Managed by the local government, specifically the USDA NRCS, East Fork Big Creek Dam Lt- 23 is classified as having a low hazard potential and a moderate risk level. The dam features an uncontrolled spillway with a width of 10 feet and no outlet gates. Despite not being regulated by the state, the dam's condition is currently not rated, and it has not undergone recent inspections. While the dam may not currently meet all modern guidelines, it continues to provide essential grade stabilization functions for the surrounding area.
As an important structure in the Rock Island District, East Fork Big Creek Dam Lt- 23 stands as a testament to the ongoing efforts to manage water resources and mitigate the effects of climate change in Missouri. With its strategic location and design, the dam remains a key component in the local water infrastructure, demonstrating the importance of sustainable water management practices for the long-term well-being of the community.

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.
