Winegar Lake Dam dam
Winegar Lake Dam
Winegar Lake Dam, located in Jefferson City, Missouri, was completed in 1978 with a primary purpose of flood risk reduction. This private Earth dam with a height of 28 feet holds a storage capacity of 150 acre-feet, serving a drainage area of 160 square miles. While the dam is not state-regulated, it is noted to have a high hazard potential, though its condition assessment is currently not rated.
Although the dam lacks certain regulatory oversight, its importance in flood risk reduction cannot be overstated. With a normal storage capacity of 80 acre-feet, the dam plays a crucial role in mitigating flood events in the surrounding area. Additionally, Winegar Lake Dam also serves purposes such as fire protection, stock or small fish pond, and recreation, highlighting its versatility and value to the local community.
Furthermore, situated on the TR-South Moreau Creek, Winegar Lake Dam is under the jurisdiction of the St. Louis District of the US Army Corps of Engineers. Even though the dam has not been inspected recently and its Emergency Action Plan status is unknown, it remains a vital structure for managing water resources and climate-related risks in the region. Enthusiasts interested in water resource management and climate adaptation efforts will find Winegar Lake Dam to be a compelling case study of a private dam contributing to flood risk reduction and community resilience.

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 Winegar Lake Dam
Where does the data for Winegar 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.
