Summary
Built in 1954 by the USDA NRCS, this dam serves the primary purpose of flood risk reduction along the Little Sixmile Creek. Standing at a height of 34 feet with a hydraulic height of 27.7 feet and a structural height of 45.1 feet, the dam has a storage capacity of 2950 acre-feet and a drainage area of 6.2 square miles.
With a low hazard potential and a moderate risk assessment rating of 3, Sixmile Creek Wid Site 09 is regulated by the ANRC, with state permitting, inspection, and enforcement in place to ensure its safety and compliance. The dam features an uncontrolled spillway and outlet gates, with a maximum discharge capacity of 10,125 cubic feet per second. Although the condition assessment is currently not rated, the structure has not undergone any modifications since its completion, indicating its stable and well-maintained state.
For water resource and climate enthusiasts, Sixmile Creek Wid Site 09 presents an interesting case study of a privately owned earth dam designed for flood risk reduction in a rural setting. Its location in the city of CHISMVILLE, its association with the Natural Resources Conservation Service, and its historical completion in 1954 add to the intrigue of this important water management infrastructure. As efforts continue to monitor and manage the dam's safety and functionality, its role in protecting the surrounding area from flooding remains vital to the community and ecosystem.

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.
