Holesinger Dam dam
Holesinger Dam
Holesinger Dam, located in Clinton, Iowa, was completed in 2004 and serves multiple purposes, including fire protection and providing a small fish pond. The dam, designed by Landmark Engineering Group, is privately owned and regulated by the Iowa Department of Natural Resources. With a height of 25 feet and a length of 665 feet, the dam has a storage capacity of 94 acre-feet and a surface area of 12 acres.
The dam, constructed with earth and soil foundations, has an uncontrolled spillway with a width of 2 feet. It is rated as having low hazard potential and moderate risk. While the condition assessment is currently not rated, regular inspections, enforcement, and permitting by the state ensure its safety and functionality. Holesinger Dam is a valuable resource for the community, providing essential services while also contributing to water conservation and management efforts in the region.
Water resource and climate enthusiasts will appreciate the role of Holesinger Dam in maintaining water levels and supporting local ecosystems along the TR-Mill Creek. Its strategic location and design make it a key asset for fire protection and stock purposes. With its low hazard potential and moderate risk rating, the dam stands as a reliable structure that reflects responsible management and regulation by the Iowa DNR. Its completion in 2004 marked a significant milestone in enhancing water infrastructure in Clinton, Iowa, and highlights the importance of sustainable water resource management in the region.

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 Holesinger Dam
Where does the data for Holesinger 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.
