Summary
Built in 1981 by the USDA NRCS, this earth dam stands at a height of 40 feet and spans 350 feet in length. With a storage capacity of 34 acre-feet, it serves the primary purpose of flood risk reduction for the local community.
Managed by the Iowa DNR, this dam is considered to have a significant hazard potential and a moderate risk assessment rating. While its condition is currently not rated, the dam is regularly inspected and maintained to ensure its effectiveness in protecting the surrounding area from potential flooding events. Despite its uncontrolled spillway type, the Bacon Creek Watershed Site H-1-2 plays a crucial role in mitigating flood risks and safeguarding the local environment.
For water resource and climate enthusiasts, Bacon Creek Watershed Site H-1-2 serves as a prime example of infrastructure designed to address the challenges of extreme weather events. As part of the broader efforts to manage water resources and reduce flood risks in the region, this dam stands as a testament to the collaborative efforts between local government agencies and federal partners like the USDA NRCS. With its strategic location and purpose-driven design, the Bacon Creek Watershed Site H-1-2 plays a vital role in protecting the community and enhancing resilience in the face of changing climatic conditions.

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.
