Clermont Milldam dam
Clermont Milldam
Located in Clermont, Iowa, the Clermont Milldam is a gravity dam constructed in 1925 for recreational purposes along the Turkey River. With a height of 16 feet and a length of 248 feet, the dam provides a storage capacity of 578 acre-feet and covers a surface area of 70 acres. While the dam is primarily used for recreation, it is also regulated by the Iowa Department of Natural Resources, ensuring its safety and compliance with state regulations.
The dam's low hazard potential and moderate risk assessment make it a key feature in the region for both water resource management and climate enthusiasts. While the condition assessment is currently marked as "Not Rated," the dam's design and construction using soil foundations reflect its sturdy build and functionality. The Clermont Milldam serves as a vital component in the local water management system, showcasing the integration of natural resources with recreational activities along the Turkey River.
With its picturesque location and historical significance, the Clermont Milldam stands as a testament to Iowa's dedication to water resource management and conservation. As a popular spot for outdoor enthusiasts and nature lovers, the dam's presence along the Turkey River adds to the beauty and charm of the Fayette County landscape. Its regulated status and regular inspections highlight the commitment to maintaining the dam's integrity and ensuring the safety of all who visit this iconic water resource site.
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 Clermont Milldam
Where does the data for Clermont Milldam 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.
