Hiatt Dam dam
Hiatt Dam
Located in Union County, Iowa, the Hiatt Dam stands as a testament to reliable water resource management since its completion in 1968. This private-owned earth dam serves multiple purposes, including fire protection and creating a stock or small fish pond. With a height of 22 feet and a length of 547 feet, the dam has a storage capacity of 58 acre-feet, with a normal storage level of 31 acre-feet and a surface area of 4.5 acres.
Managed by the Iowa Department of Natural Resources, the Hiatt Dam is designed by the USDA NRCS and regulated by the state to ensure its safety and functionality. The dam's low hazard potential and moderate risk assessment rating make it a crucial component of the local water infrastructure, providing essential water resources to the surrounding community. With its location on the TR-East Platte River and close proximity to the city of Maloy, the dam plays a vital role in maintaining water quality and availability in the region.
Despite not having been rated for its current condition, the Hiatt Dam continues to be inspected, demonstrating a commitment to regular maintenance and upkeep. With its uncontrolled spillway type and soil foundation, the dam showcases environmentally conscious design while serving as a reliable resource for water storage and management. For water resource and climate enthusiasts, the Hiatt Dam is a prime example of sustainable water infrastructure that plays a crucial role in mitigating the impacts of climate change on water availability 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 Hiatt Dam
Where does the data for Hiatt 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.
