Walnut Creek Dam Site 2 dam
Walnut Creek Dam Site 2
Walnut Creek Dam Site 2, located in Jefferson County, Iowa, is a privately owned earth dam completed in 1995 for fire protection, livestock watering, and small fish pond purposes. Managed by the USDA NRCS, this dam on the TR-S. Walnut Creek has a height of 25 feet and a length of 397 feet, providing a storage capacity of 158 acre-feet and covering a surface area of 11.7 acres. The dam is regulated by the Iowa DNR and meets state permitting, inspection, and enforcement requirements.
Despite its low hazard potential, Walnut Creek Dam Site 2 has been rated as having a moderate risk level due to its location and potential downstream impacts. The dam's condition is currently unrated, and there is no emergency action plan in place. However, the risk management measures and guidelines for this dam are not specified. With its controlled spillway and soil foundation, this dam serves as a crucial water resource for the surrounding area, highlighting the importance of monitoring and maintaining its structural integrity for both water supply and flood protection purposes.
Water resource and climate enthusiasts interested in Walnut Creek Dam Site 2 can appreciate its vital role in providing fire protection, livestock watering, and recreational opportunities in the area. The involvement of the USDA NRCS, Iowa DNR, and other regulatory agencies ensures that the dam meets state standards for safety and operation. As part of the larger watershed system, this dam plays a significant role in managing surface water and supporting the local ecosystem. Continued monitoring and risk assessment will be essential to safeguarding the community and environment from potential hazards associated with the dam.

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 Walnut Creek Dam Site 2
Where does the data for Walnut Creek Dam 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 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.
