Lake Acres Dam dam
Lake Acres Dam
Lake Acres Dam, located in Osage, Missouri, is a privately owned structure primarily used for recreation purposes. Built in 1955, this earth dam stands at a height of 30 feet and has a storage capacity of 144 acre-feet. With a normal storage capacity of 81 acre-feet and a surface area of 9 acres, the dam serves the local community and visitors for various outdoor activities.
Situated on TR-Indian Creek, Lake Acres Dam is managed by private owners and is not regulated or inspected by state agencies. Despite its high hazard potential, the dam's condition assessment remains unrated. With no emergency action plan in place and no updated inundation maps, the risk management and emergency response procedures at the dam are unclear. The lack of regular inspections and assessments raises concerns about the long-term safety and stability of the structure.
For water resource and climate enthusiasts, Lake Acres Dam serves as a point of interest due to its historical significance and recreational value. As a privately owned earth dam with a high hazard potential, there is a need for increased oversight and maintenance to ensure the safety of the surrounding community and the preservation of the dam for future generations. Efforts to update emergency action plans, conduct regular inspections, and implement risk management measures are essential to mitigate potential risks and enhance the resilience of this important water resource 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 Lake Acres Dam
Where does the data for Lake Acres 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.
