Summary
Completed in 1978, this earth dam stands at a height of 64 feet and stretches 420 feet in length, providing a storage capacity of 83 acre-feet to mitigate flooding along TR-Bacon Creek. With a surface area of 3.1 acres and a drainage area of 0.14 square miles, this low hazard potential dam plays a crucial role in protecting the surrounding area from potential flood risks.
Managed by the Iowa DNR, Bacon Creek Watershed Site A-2 is subject to state regulations, permitting, inspections, and enforcement to ensure its continued effectiveness in flood risk reduction. Despite not being rated for its condition, this structure has been deemed to have a moderate risk level, underscoring the importance of ongoing monitoring and maintenance. Although currently not associated with any federal agency funding or construction, this dam serves multiple purposes including fire protection, stock or small fish pond, and flood risk reduction, highlighting its value in supporting both environmental and community needs.
With its strategic location and purposeful design, Bacon Creek Watershed Site A-2 stands as a testament to effective water resource management in the region. As water resource and climate enthusiasts, understanding the significance of this structure in safeguarding against flooding and promoting sustainable water use is essential for fostering a resilient and environmentally conscious community in Sioux City, Iowa.

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.
