Aspenhoff Lake Dam dam
Aspenhoff Lake Dam
Aspenhoff Lake Dam, located in Warren, Missouri, is a privately owned structure built in 1965 for recreational purposes. Standing at a height of 29 feet, the dam serves as a barrier to the TR-Hopewell Creek, providing a storage capacity of 186 acre-feet. With a surface area of 12 acres and a drainage area of 211 square miles, the dam offers a tranquil setting for outdoor enthusiasts to enjoy water-based activities.
Despite being privately owned and not regulated by the state, Aspenhoff Lake Dam has a high hazard potential due to its condition assessment being labeled as "not rated." The last inspection date recorded was in 1979, with no recent updates on the dam's emergency action plan or risk management measures. With its scenic location and recreational purpose, it is crucial for stakeholders to prioritize the safety and maintenance of Aspenhoff Lake Dam to prevent any potential hazards or risks to the surrounding community and environment.
In the heart of Missouri's natural beauty, Aspenhoff Lake Dam stands as a reminder of the delicate balance between water resource management and climate resilience. As water resource and climate enthusiasts, there is a call to action to ensure the sustainability and safety of structures like Aspenhoff Lake Dam, emphasizing the importance of regular inspections, updated emergency action plans, and risk management measures to protect both the recreational value and environmental integrity of this treasured site.

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 Aspenhoff Lake Dam
Where does the data for Aspenhoff 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.
