Three Mile Creek Watershed Site 29 dam
Three Mile Creek Watershed Site 29
Three Mile Creek Watershed Site 29, located in Talmage, Iowa, is a vital resource managed by the local government for purposes such as fire protection, stock, and small fish pond management. This Earth-type dam, completed in 1970, stands at a height of 33 feet with a length of 403 feet, providing a storage capacity of 58 acre-feet for flood risk reduction. The dam is regulated by the Iowa Department of Natural Resources and has a low hazard potential, making it a crucial asset in the region's water resource management strategy.
Managed by the USDA NRCS, Three Mile Creek Watershed Site 29 plays a significant role in the protection and conservation of the local environment. With a drainage area of 0.1 square miles and a surface area of 3.5 acres, this dam contributes to the overall water quality and quantity in the area. Despite being uncontrolled, the spillway can effectively manage excess water flow during heavy rainfall events, reducing the risk of downstream flooding. Additionally, the dam poses a moderate risk level, emphasizing the need for continued monitoring and maintenance to ensure its long-term effectiveness.
Cindy Axne (D) represents Three Mile Creek Watershed Site 29 in the US House of Representatives, highlighting the importance of this water management infrastructure at the federal level. With its strategic location in Union County, Iowa, this dam serves as a critical asset for the community, providing essential services while enhancing the resilience of the local ecosystem. By staying proactive in risk assessment and management, stakeholders can maximize the benefits of this dam while safeguarding against potential hazards and ensuring sustainable water resource management for future generations.

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 Three Mile Creek Watershed Site 29
Where does the data for Three Mile Creek Watershed Site 29 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.
