Indian Creek Watershed Site 2 dam
Indian Creek Watershed Site 2
Indian Creek Watershed Site 2, located in Pottawattamie, Iowa, is a vital flood risk reduction structure designed by the USDA NRCS in 1975. 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.

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.
- 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.
- 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.
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, environmental 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.

About Indian Creek Watershed Site 2
Where does the data for Indian Creek Watershed Site 2 come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the High hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
