Genteman Lake Dam dam
Genteman Lake Dam
Genteman Lake Dam, located in Chain of Rocks, Missouri, is a privately-owned structure with a primary purpose that goes beyond just water resource management. Built in 1957, this Earth dam stands at a height of 30 feet and has a storage capacity of 96 acre-feet. Although not regulated by the state, the dam has a high hazard potential, making it crucial for regular inspections and emergency preparedness.
With its location on TR-Coon Creek and its close proximity to the Kansas City District, Genteman Lake Dam serves as an important structure for managing water resources in Lincoln County, Missouri. Despite not having a spillway or outlet gates, the dam plays a significant role in storing and regulating water flow in the area. The dam's condition is currently rated as "Not Rated," highlighting the need for ongoing monitoring and maintenance to ensure the safety and efficiency of this vital structure.
For water resource and climate enthusiasts, Genteman Lake Dam offers a glimpse into the intersection of infrastructure, environmental stewardship, and community safety. As a privately-owned Earth dam with a high hazard potential, the dam serves as a reminder of the importance of proper management and upkeep of critical water structures. With its capacity to store 96 acre-feet of water and its location within the Chain of Rocks community, Genteman Lake Dam stands as a testament to the intricate balance between human development and natural resource conservation in the face of changing climate patterns.

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 Genteman Lake Dam
Where does the data for Genteman 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.
