Summary
Completed in 1981, this earth dam stands at a height of 59 feet and has a storage capacity of 144 acre-feet. With a drainage area of 0.17 square miles and a surface area of 5.8 acres, this structure plays a crucial role in managing water resources in the region.
The dam, situated on the TR-Floyd River, serves multiple purposes including fire protection, stock, small fish pond, and flood risk reduction. Despite its significant hazard potential, the structure was found to be in satisfactory condition during the last assessment in June 2016. With a moderate risk assessment rating, the Bacon Creek Watershed Site H-2-1 is an essential component of water resource management in the area, ensuring the safety and security of the surrounding community in Sioux City.
As a key infrastructure owned by the local government, this dam undergoes regular inspections to maintain its integrity and functionality. With a spillway width of 2 feet and uncontrolled spillway type, the structure is equipped to handle any excess water flow during heavy rainfall events. Overall, the Bacon Creek Watershed Site H-2-1 stands as a testament to effective water resource management and climate resilience in the region, serving as a vital asset in protecting the community from flooding and other water-related hazards.

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.
