Summary
This earth dam stands at a height of 24.5 feet and has a hydraulic height of 16 feet, providing a storage capacity of 146.25 acre-feet to help mitigate potential flooding in the area. With a low hazard potential and a moderate risk assessment rating, this dam plays a crucial role in managing water resources and protecting the surrounding community from potential flood events.
The structure, with a length of 690 feet and a spillway width of 30 feet, is designed to handle a maximum discharge of 199.8 cubic feet per second. Despite not being state-regulated or inspected, the dam has not been rated for its current condition. The risk management measures and emergency action plans for this dam are not specified, but its presence and functionality serve as a vital component in the overall water resource management infrastructure in the region. Water resource and climate enthusiasts will find the data on this dam essential for understanding its role in flood prevention and risk reduction efforts in the area.
Overall, the Big Creek-Hurricane Creek H-40 dam stands as a testament to the collaborative efforts of the USDA NRCS in partnership with local government agencies to address flood risk in the region. With its strategic location and design features, this earth dam contributes significantly to the overall water resource management system in Carroll County, Missouri. As climate change continues to impact hydrological patterns, the importance of structures like the Big Creek-Hurricane Creek H-40 dam in safeguarding communities from flooding events cannot be overstated.

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.
