Summary
Constructed in 1988, this earth dam with a buttress core stands at a height of 19 feet and has a storage capacity of 51 acre-feet. With a significant hazard potential and a condition assessment that is not rated, this structure plays a key role in managing water resources in the area.
Owned by the local government, Structure R-6 is not regulated by the state and does not have a state inspection or enforcement program in place. Despite its importance for irrigation, the dam's condition assessment remains unknown, highlighting the need for further evaluation and maintenance. With a drainage area of 150 square miles and a normal storage capacity of 32 acre-feet, this dam serves a vital role in water management in Carroll County, Missouri.
While the specifics of the dam's spillway type and width are not provided, Structure R-6 remains a critical infrastructure for water resource management in the region. With a capacity to store 51 acre-feet of water and a surface area of 5 acres, this dam plays a crucial role in ensuring water availability for irrigation purposes along Big Creek. As climate change continues to impact water resources, monitoring and maintaining structures like R-6 will be essential for sustainable water management in the area.

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.
