Mendenhall Lake Dam dam
Mendenhall Lake Dam
Located in Lawrence, Missouri, the Mendenhall Lake Dam is a private Earth dam primarily used for recreation purposes. Standing at a height of 20 feet, the dam holds a storage capacity of 86 acre-feet and covers a surface area of 8 acres. With a low hazard potential and a condition assessment that is not yet rated, the dam serves as a key feature along TR-JOHNSON CREEK, providing both scenic beauty and recreational opportunities for visitors.
Despite being privately owned and not regulated by the state, the Mendenhall Lake Dam remains a crucial part of the local landscape, offering residents and tourists a serene spot for outdoor activities. The dam's buttress core type and unlisted/unknown foundation contribute to its structural integrity, while its location near the city of PENNSBORO makes it easily accessible to the public. As a privately owned structure, the dam's maintenance and upkeep are essential to ensure its continued safety and functionality for water resource and climate enthusiasts to enjoy.
While the dam's emergency action plan and risk management measures are currently not specified, its significance in providing recreation opportunities and enhancing the natural beauty of the area cannot be understated. With a focus on safety and conservation, the Mendenhall Lake Dam stands as a testament to the importance of responsible water resource management and the harmonious coexistence of human recreation with the surrounding environment.

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.
Plan around the weather

About Mendenhall Lake Dam
Where does the data for Mendenhall 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.
