Hermora Lake Dam dam
Hermora Lake Dam
Hermora Lake Dam, located in Pettis, Missouri, was completed in 1964 and serves as a recreational site for water and climate enthusiasts. The dam is privately owned and has a primary purpose of recreation, offering a serene escape for visitors looking to enjoy the surrounding natural beauty. With a height of 26 feet and a storage capacity of 209 acre-feet, Hermora Lake Dam provides ample opportunities for boating, fishing, and other water activities in its 15-acre surface area.
Despite being privately owned, Hermora Lake Dam is not regulated by the state and has a high hazard potential. The dam's condition is currently not rated, indicating a lack of recent assessment. While there are no associated structures or locks, the dam's purpose of recreation highlights the importance of maintaining its safety and integrity for the enjoyment and safety of visitors. As a significant feature in the Kansas City District, Hermora Lake Dam stands as a reminder of the balance between water resource management and recreational opportunities in the region.
In the absence of state regulation and inspections, Hermora Lake Dam's risk assessment and management measures remain unclear. However, with its location along TR-Flat Creek and its proximity to Otterville, the dam plays a crucial role in providing recreational opportunities for the local community. As water and climate enthusiasts continue to explore the area, the safety and maintenance of Hermora Lake Dam will be essential in ensuring a sustainable and enjoyable environment for all who visit.

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 Hermora Lake Dam
Where does the data for Hermora 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.
