Wolf Creek Subwatershed Site M-2 dam
Wolf Creek Subwatershed Site M-2
Wolf Creek Subwatershed Site M-2, located in Woodbury County, Iowa, is a key water resource infrastructure managed by the local government and designed by the USDA NRCS. This earth dam, constructed in 1971, serves multiple purposes including fire protection, stock management, and small fish pond creation, as well as flood risk reduction. With a height of 30 feet and a length of 711 feet, the dam has a storage capacity of 174 acre-feet and covers a surface area of 10.5 acres.
The dam is regulated by the Iowa Department of Natural Resources and is subject to state permitting, inspection, and enforcement. Despite having a low hazard potential and a moderate risk assessment rating, the condition of the dam is currently not rated. The spillway type is uncontrolled, and there are no outlet gates or associated structures. While the dam has not been modified in recent years, it remains a crucial component of the Wolf Creek watershed, providing essential water management functions for the surrounding area.
Overall, Wolf Creek Subwatershed Site M-2 plays a vital role in water resource management in the region, serving as a resilient infrastructure for flood risk reduction and water storage. As climate change impacts water availability and quality, the proper maintenance and monitoring of dams like Site M-2 are essential to ensure the safety and sustainability of water resources for future generations. With its multiple purposes and regulatory oversight, this dam stands as a testament to the importance of integrated water resource management in the face of a changing climate.

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 Wolf Creek Subwatershed Site M-2
Where does the data for Wolf Creek Subwatershed Site M-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.
