Heyen Lake Dam dam
Heyen Lake Dam
Heyen Lake Dam, located in Fayette, Missouri, was completed in 1973 and serves primarily for irrigation purposes. Owned privately, this earth dam with a buttress core stands at a height of 24 feet and has a storage capacity of 244 acre-feet. The dam is situated along the TR-BONNE FEMME CREEK and has a drainage area of 390 acres, providing crucial water resources for the surrounding area.
With a surface area of 19 acres, Heyen Lake Dam offers recreational opportunities in addition to its irrigation function. Despite its high hazard potential, the dam's condition assessment remains unrated, and emergency preparedness measures such as an Emergency Action Plan (EAP) have not been documented. This dam presents an important site for water resource and climate enthusiasts to monitor and advocate for proper maintenance and risk management practices to ensure the safety and sustainability of its operations.
As a key feature in the water infrastructure of Howard County, Missouri, Heyen Lake Dam plays a crucial role in water management and conservation efforts. Its location within the Kansas City District underlines its significance in the region, highlighting the need for continued monitoring and assessment to safeguard its structural integrity and functionality. Water enthusiasts and environmental advocates can use Heyen Lake Dam as a case study for understanding the intersection of water resource management, climate resilience, and the importance of proactive maintenance in safeguarding vital infrastructure.

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 Heyen Lake Dam
Where does the data for Heyen 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.
