Heim Lake Dam dam
Heim Lake Dam
Heim Lake Dam, located in Audrain County, Missouri, is a privately owned structure completed in 1976 for the primary purpose of irrigation. The dam stands at a height of 31 feet and has a storage capacity of 232 acre-feet, with a normal storage level of 135 acre-feet. Although it is not state-regulated, the dam is classified as having a low hazard potential and is currently listed as "Not Rated" in terms of condition assessment.
Situated on the West Fork Cuivre River, Heim Lake Dam serves as a vital water resource for the surrounding area, providing irrigation for agricultural purposes. The dam's earth construction, buttress core type, and unlisted/unknown foundation contribute to its structural integrity. Despite the lack of recent inspection data, the dam's emergency action plan status and risk management measures remain undisclosed, leaving room for further evaluation and potential updates to ensure its safety and functionality for the future.
Water resource and climate enthusiasts interested in Heim Lake Dam can appreciate its role in sustaining the local ecosystem and supporting agriculture in the region. The dam's history, design features, and storage capacity highlight its importance in water management and the potential implications for climate resilience. Further monitoring and risk assessment may be necessary to ensure the continued effectiveness and safety of this essential 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 Heim Lake Dam
Where does the data for Heim 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 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.
