Wenger Subwatershed M 130+73 dam
Wenger Subwatershed M 130+73
The Wenger Subwatershed M 130+73 is a locally owned earth dam in Woodbury County, Iowa, designed by the USDA NRCS and regulated by the Iowa DNR. Completed in 1965, this dam serves multiple purposes including fire protection, stock watering, small fish pond, and flood risk reduction. With a height of 30 feet and a length of 642 feet, it has a storage capacity of 181 acre-feet and covers a surface area of 10 acres. The dam is located on the TR-REYNOLDS CREEK and is inspected by state authorities for safety and regulatory compliance.
Despite being classified as having a low hazard potential, the Wenger Subwatershed M 130+73 is considered to have a moderate risk level (3) due to its condition assessment being not rated. The dam has not been modified in recent years and does not have emergency action plans (EAP) in place. While the dam meets regulatory guidelines, there are no specific risk management measures identified for this structure at this time. As climate change continues to impact water resources and infrastructure, monitoring and maintenance of dams like Wenger Subwatershed M 130+73 will be crucial for ensuring the safety and resilience of communities in the region.
Overall, the Wenger Subwatershed M 130+73 plays a vital role in water management in Woodbury County, Iowa, providing essential services while also posing a moderate risk level that requires continued attention and monitoring. As water resource and climate enthusiasts, it is important to recognize the significance of infrastructure like this dam in maintaining the balance between water supply, flood control, and ecosystem health. Collaboration between local, state, and federal agencies will be essential in ensuring the long-term sustainability and safety of Wenger Subwatershed M 130+73 and other similar structures in the region.
Dam data reference
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 Wenger Subwatershed M 130+73
Where does the data for Wenger Subwatershed M 130+73 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.
