Twelve Mile Creek Watershed Site 62-5 dam
Twelve Mile Creek Watershed Site 62-5
Twelve Mile Creek Watershed Site 62-5, located in Davis City, Iowa, is a grade stabilization structure designed by the USDA NRCS and completed in 2003. This earth dam stands at 36 feet in height and spans 412 feet in length, with a storage capacity of 131 acre-feet. It serves the primary purpose of grade stabilization in the Twelve Mile Creek watershed, which covers a drainage area of 0.5 square miles.
Managed by the local government and regulated by the Iowa DNR, this dam has a low hazard potential and a moderate risk assessment rating of 3. While its condition has not been rated, it is inspected, permitted, and enforced by state agencies. Despite its small surface area of 0.4 acres, the dam plays a crucial role in water resource management in the region, ensuring the protection of nearby communities from potential flooding and erosion risks.
With a controlled spillway type and no locks or gates, Twelve Mile Creek Watershed Site 62-5 remains an essential structure in the Rock Island District. Its presence contributes to the overall resilience of the area against climate change impacts, highlighting the importance of sustainable water resource management practices in safeguarding communities and ecosystems for the future.

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 Twelve Mile Creek Watershed Site 62-5
Where does the data for Twelve Mile Creek Watershed Site 62-5 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 Low 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.
