Summary

This earth dam, standing at 55 feet tall and stretching 412 feet in length, plays a crucial role in protecting the surrounding area from potential flooding events. With a storage capacity of 196 acre-feet and a drainage area of 0.32 square miles, the dam serves as a vital resource for managing water flow in the region.

Located along the TR-Floyd River in Sioux City, this site is regulated by the Iowa DNR and undergoes regular inspections to ensure its structural integrity and functionality. The dam's hazard potential is deemed significant, highlighting the importance of its maintenance and upkeep. Despite this, the condition assessment remains satisfactory, indicating that the structure is currently in good working order. With a risk assessment rating of moderate, it is clear that this watershed site is a crucial component of the local water resource management infrastructure.

Overall, Bacon Creek Watershed Site H-3-1 serves as a critical flood risk reduction measure in Woodbury County, Iowa. With its strategic location, design by the USDA NRCS, and state regulation by the Iowa DNR, this earth dam plays a vital role in safeguarding the surrounding area from potential inundation. As climate change continues to pose challenges to water resource management, structures like this are essential for mitigating flood risks and ensuring the resilience of communities in the face of changing environmental conditions.

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.
