Summary
This earth dam stands at a height of 65 feet and spans a length of 2000 feet, providing crucial protection to the surrounding area against potential flooding events. With a storage capacity of 767 acre-feet and a drainage area of 1.07 square miles, this structure plays a significant role in managing water flow and mitigating flood risks along Indian Creek.
Managed by the Iowa DNR, Indian Creek Watershed Site 2 is subject to regular inspections and regulatory oversight to ensure its structural integrity and operational efficiency. The dam is classified as having a high hazard potential, highlighting the importance of its maintenance and monitoring. Despite this classification, the condition assessment conducted in August 2019 deemed the structure to be in satisfactory condition, reflecting the diligence of the overseeing authorities in ensuring its effectiveness in flood risk reduction. With a moderate risk assessment rating, ongoing risk management measures and emergency preparedness protocols are crucial to safeguarding the surrounding communities and environment from potential hazards associated with the dam.
Indian Creek Watershed Site 2 serves as a critical infrastructure for flood risk reduction and grade stabilization along Indian Creek in Council Bluffs, Iowa. As a key component of the local government's water resource management strategy, this earth dam exemplifies the collaborative efforts between state and federal agencies, such as the Iowa DNR and USDA NRCS, in safeguarding communities and enhancing resilience to climate-related challenges. The structure's historic significance, combined with its modern-day operational effectiveness and regulatory compliance, underscores its essential role in ensuring water resource sustainability and climate resilience in the region.

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.
