Hiatt Dam dam
Hiatt Dam
Hiatt Dam, located in Macon, Missouri, along the TR-East Fork Little Chariton River, is a privately owned earth dam designed by the USDA NRCS for the primary purpose of grade stabilization. Completed in 2003, this dam stands at 31 feet tall with a hydraulic height of 24 feet and a length of 450 feet. With a maximum storage capacity of 47 acre-feet and a normal storage of 37 acre-feet, the dam serves to control the flow of water in the area while also providing some flood protection.
The dam features an uncontrolled spillway with a width of 10 feet and has a low hazard potential. Despite not being rated for its condition assessment, the risk assessment for Hiatt Dam is moderate. The dam has not been inspected since September 2003, but it is noted that there are no outlet gates associated with the structure. While the dam does not fall under state jurisdiction for regulation, inspection, or enforcement, it plays a crucial role in managing water resources in the region and contributes to the overall climate resilience of the area.
Overall, Hiatt Dam is a vital infrastructure for water resource management in Macon, Missouri, serving the community by providing grade stabilization and moderate flood protection along the TR-East Fork Little Chariton River. With a focus on maintaining its structural integrity and monitoring its risk assessment, the dam continues to play a significant role in the local water management system. As water resource and climate enthusiasts, understanding the details of this earth dam's design, purpose, and capacity can deepen appreciation for the essential role it plays in the region's hydrological landscape.

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.
