Summary
The dam was designed by the USDA NRCS and completed in 2010 with a primary purpose of flood risk reduction along the TR-Lick Branch river or stream. Standing at a height of 24.4 feet and a length of 710 feet, the dam has a storage capacity of 212.7 acre-feet and serves a drainage area of 170.24 square miles.
Despite its low hazard potential and moderate risk assessment rating, the condition of Big Creek-Hurricane Creek L-6 is currently marked as "Not Rated" in terms of its structural integrity and maintenance. With no recent inspection date or emergency action plan in place, there is a need for ongoing monitoring and risk management to ensure the dam's effectiveness in flood risk reduction. The spillway type of the dam is uncontrolled with a width of 34 feet, allowing for a maximum discharge of 177.7 cubic feet per second.
Overall, Big Creek-Hurricane Creek L-6 plays a crucial role in mitigating flood risks in the area and protecting the surrounding communities from potential inundation. As a part of the Rock Island District, the dam stands as a testament to the collaborative efforts between local government and federal agencies in safeguarding water resources and managing climate-related risks in Missouri. Continued vigilance and maintenance will be key in ensuring the long-term functionality and safety of this important infrastructure.

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.
