Carroll Stormwater Detention Dam dam
Carroll Stormwater Detention Dam
Located in Carroll, Iowa, the Carroll Stormwater Detention Dam stands as a vital structure designed by BRICE-PETRIDES in 1985 for flood risk reduction along the TR-MIDDLE RACCOON R. river. With a dam height of 13 feet and a length of 1100 feet, this earth dam with a soil foundation provides a storage capacity of 518 acre-feet to mitigate potential flooding in the area. The dam is regulated by the Iowa DNR and undergoes regular inspections to ensure its satisfactory condition and high hazard potential.
Managed by the local government, the Carroll Stormwater Detention Dam plays a crucial role in protecting the surrounding area from the impacts of extreme weather events. Despite its uncontrolled spillway type, the dam's risk assessment is moderate, with emergency preparedness measures in place to address any potential threats. With a history of compliance with regulatory agencies and a focus on flood risk reduction as its primary purpose, the dam serves as a key component of the region's water resource management infrastructure.
For water resource and climate enthusiasts, the Carroll Stormwater Detention Dam represents a tangible example of how engineering solutions can help mitigate the impacts of natural disasters. As a significant structure in the Omaha District, the dam's construction and ongoing maintenance highlight the importance of proactive measures in safeguarding communities against the uncertainties of a changing climate. With a focus on risk management and regulatory compliance, this dam stands as a testament to the intersection of environmental stewardship and public safety in the face of water-related challenges.

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 Carroll Stormwater Detention Dam
Where does the data for Carroll Stormwater Detention Dam 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.
