Heston Dam dam
Heston Dam
Heston Dam, located in Appanoose, Iowa, is a privately owned earth dam with a primary purpose of fire protection, stock, or small fish pond. Completed in 1999, this dam stands at 26 feet high and stretches 300 feet in length, with a storage capacity of 40 acre-feet. Situated on Tr- Shoal Creek in the State of Missouri, Heston Dam is regulated by the Iowa Department of Natural Resources and undergoes regular inspections to ensure its safety and functionality.
With a low hazard potential and a moderate risk assessment rating, Heston Dam plays a crucial role in providing water resources for fire protection and agricultural purposes in the surrounding area. The dam's uncontrolled spillway and soil foundation contribute to its effective water management capabilities, while its location within the Rock Island District enhances its overall impact on water conservation efforts. Despite not being rated for condition assessment, Heston Dam remains a key structure for maintaining water levels and supporting local ecosystems in the region.
As a significant water resource in the region, Heston Dam serves as a testament to the importance of sustainable water management practices in mitigating climate change impacts. With its strategic design by the NRCS and ongoing regulatory oversight by the Iowa DNR, Heston Dam stands as a vital infrastructure for promoting water conservation, agricultural sustainability, and environmental resilience in the face of changing climate patterns. The dam's role in protecting against floods and providing essential water supplies highlights its critical contribution to the overall well-being of the local community and surrounding ecosystems.

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.
Plan around the weather
Same NOAA / yr.no feed Snoflo's iOS app uses. Watch the precipitation column on the meteogram -- rain on the basin upstream typically lifts inflow 24-72 hours later.

About Heston Dam
Where does the data for Heston 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.
