Hardin County Wetland Dam dam
Hardin County Wetland Dam
Located in Hardin County, Iowa, the Hardin County Wetland Dam serves as a vital resource for the local community and surrounding areas. Completed in 1993, this earth dam stands at a height of 11 feet and has a length of 1375 feet, providing a storage capacity of 66 acre-feet. The primary purpose of the dam is for recreation and other purposes, making it a valuable asset for water resource and climate enthusiasts.
Managed by the Iowa Department of Natural Resources, the dam is regulated and inspected regularly to ensure its structural integrity and safety. With a low hazard potential and a moderate risk assessment rating, the Hardin County Wetland Dam plays a crucial role in flood control and water management along the TR- Iowa River. The dam also features an uncontrolled spillway type, further enhancing its ability to handle excess water discharge during heavy rainfall events.
As a key feature in the local landscape, the Hardin County Wetland Dam provides not only recreational opportunities but also serves as a critical infrastructure for managing water resources in the region. With its strategic location and low hazard potential, the dam continues to play a significant role in protecting the surrounding communities from potential flooding events. For water resource and climate enthusiasts, this dam represents a prime example of effective water management and infrastructure development in the state of Iowa.

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 Hardin County Wetland Dam
Where does the data for Hardin County Wetland 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.
