Skubal Dam dam
Skubal Dam
Skubal Dam, located in Washington County, Iowa, is a privately owned structure designed by the USDA NRCS with a primary purpose of fire protection, stock, or small fish pond. Completed in 1975, this earth dam stands at a height of 31 feet and has a length of 360 feet, providing a storage capacity of 47 acre-feet. The dam, situated on TR-WHISKEY CREEK, serves as a vital resource for water management in the area, with a low hazard potential and a moderate risk assessment rating.
Managed by the Iowa Department of Natural Resources, Skubal Dam is subject to state regulations, permitting, inspections, and enforcement to ensure its safety and compliance with standards. The dam's spillway type is uncontrolled, with a surface area of 4 acres and a drainage area of 0.17 square miles. Despite not being rated for its condition, the dam's risk assessment is moderate, highlighting the importance of ongoing monitoring and risk management measures to safeguard the surrounding community and environment.
With its location in Columbus Junction and close proximity to the Rock Island District, Skubal Dam plays a crucial role in water resource management and climate resiliency efforts in Iowa. As enthusiasts of water resources and climate change, it is important to recognize the significance of structures like Skubal Dam in providing essential services such as fire protection and stock ponds, while also being mindful of the potential risks and the need for continued assessment and maintenance to ensure its long-term effectiveness and safety.

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 Skubal Dam
Where does the data for Skubal Dam 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.
