Summary
Designed by USDA NRCS, this earth dam stands at a height of 27 feet and serves the primary purpose of flood risk reduction along the East Fork Big Creek. With a storage capacity of 168 acre-feet, the dam helps to mitigate the impact of flooding in the area.
This low hazard potential dam has a moderate risk assessment rating and is not currently regulated by the state. With a spillway width of 40 feet and a maximum discharge of 80 cubic feet per second, East Fork Big Creek Dam E- 49 plays a crucial role in managing water flow in the region. Although it has not been recently inspected or assessed for condition, the dam continues to serve its purpose effectively in protecting the surrounding community from potential flood risks.
Managed by the Natural Resources Conservation Service, East Fork Big Creek Dam E- 49 remains a key infrastructure for flood control in the area. While it is not currently under state jurisdiction or regulation, the dam's significance in reducing flood risks and its strategic location along the East Fork Big Creek highlight its importance in water resource management and climate resilience efforts in Harrison County, Missouri.

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.
