Summary
Constructed in 2006 by the USDA NRCS, this earth dam stands at a height of 25 feet with a hydraulic height of 24 feet and a structural height of 29 feet. With a storage capacity of 194.1 acre-feet, it serves the primary purpose of flood risk reduction for the area.
This dam, with a moderate hazard potential and a low risk assessment rating, features an uncontrolled spillway and outlet gates. It covers a surface area of 6.8 acres and serves a drainage area of 247 square miles. The dam has not undergone a condition assessment and inspection frequency is listed as 0, but it is noted to be in "Not Rated" condition. With a risk management plan in place, this dam plays a vital role in mitigating flood risks and protecting the surrounding environment and communities.
Despite its lack of recent inspections and condition assessments, Big Creek-Hurricane Creek B- 89 stands as a crucial infrastructure for flood risk reduction in Carroll County, Missouri. With its construction by the USDA NRCS and a storage capacity of 194.1 acre-feet, this earth dam serves to protect the area from potential flooding events. As water resource and climate enthusiasts, understanding the importance and functionality of such structures is key to appreciating the efforts put forth to safeguard our natural resources and communities.

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.
