Jamesport City Lake Dam dam
Jamesport City Lake Dam
Jamesport City Lake Dam, located in Daviess County, Missouri, was completed in 1955 and serves as a vital water supply source for the local community of Carlow. Designed by David E. Hamilton, this earth dam stands at a height of 35 feet and has a length of 580 feet, holding a maximum storage capacity of 385 acre-feet. The dam regulates the flow of TR-East Brushy Creek and has a low hazard potential, with a satisfactory condition assessment as of December 2007.
Maintained and regulated by the Dam and Reservoir Safety Program in Missouri, Jamesport City Lake Dam is subject to regular state inspections and enforcement to ensure its safety and functionality. With a moderate risk assessment rating of 3, the dam poses no immediate threat but remains under constant monitoring. Despite lacking outlet gates, the dam's uncontrolled spillway type allows for controlled discharge in case of excess water, with a maximum discharge capacity of 766 cubic feet per second.
While Jamesport City Lake Dam does not have associated structures or federal agency involvement, it plays a crucial role in providing water supply for the surrounding area and contributes to the overall water resource management in the region. As a local government-owned structure, the dam exemplifies the importance of sustainable water infrastructure for climate resilience and community well-being.

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 Jamesport City Lake Dam
Where does the data for Jamesport City 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.
