Hayes Lake Dam dam
Hayes Lake Dam
Hayes Lake Dam, located in Pettis, Missouri, is a privately owned earth dam with a buttress core type and a height of 20 feet. The dam has a storage capacity of 16 acre-feet and a surface area of 2 acres, serving a vital role in water resource management in the area. Although the dam is not regulated by the state and has not been inspected or assessed for its condition, it is classified as having a high hazard potential.
Despite its lack of recent evaluations, Hayes Lake Dam remains a crucial structure for flood control and water storage in the region. With a capacity to hold up to 16 acre-feet of water, the dam plays a significant role in managing water resources and protecting the surrounding area from potential flooding events. While there are no specific purposes listed for the dam, its existence is essential for maintaining the stability of the local ecosystem and supporting the needs of nearby communities.
Although the dam's condition is currently listed as "Not Rated" and there is no information on its completion date or recent inspections, its high hazard potential underscores the importance of continued monitoring and maintenance. As climate change impacts become more pronounced, the role of dams like Hayes Lake Dam in ensuring water security and resilience to extreme weather events will only become more critical. As such, efforts to assess and address any potential risks associated with the dam should be prioritized to safeguard the surrounding environment and communities that rely on its functions.

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 Hayes Lake Dam
Where does the data for Hayes Lake 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 High 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.
