Summary

Managed by the USDA NRCS, this earth dam stands at a height of 28 feet and serves the primary purpose of grade stabilization. Completed in 1994, the dam has a storage capacity of 185 acre-feet and covers a drainage area of 72 acres, providing vital flood control measures for the surrounding area.

With a low hazard potential and a moderate risk assessment rating, Mozingo Creek Watershed Site 12 plays a key role in managing water resources in the region. The dam's uncontrolled spillway, with a width of 30 feet, ensures efficient water discharge during heavy rainfall events. Despite being not rated for condition assessment, the structure continues to serve its intended purpose effectively, contributing to the overall water resource management efforts in the area.

Water resource and climate enthusiasts will be intrigued by the design and functionality of Mozingo Creek Watershed Site 12. Situated in the Kansas City District, this structure exemplifies the importance of sustainable water management practices in preventing floods and ensuring the safety of local communities. As a vital component of the watershed, this dam stands as a testament to the collaborative efforts between local government agencies and the USDA NRCS in safeguarding water resources for future generations.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
