Glenwilfern Lake Dam dam
Glenwilfern Lake Dam
Glenwilfern Lake Dam, located in Labarque Creek, Missouri, is a privately owned structure primarily used for recreation. The dam, completed in 1953, stands at 38 feet high and spans 540 feet in length, with a storage capacity of 114 acre-feet. The dam is classified as an earth dam with a buttress core type, serving as a key feature in the surrounding landscape.
Despite its recreational purpose, Glenwilfern Lake Dam holds a high hazard potential, with a satisfactory condition assessment as of 2007. The dam is regulated by the DAM AND RESERVOIR SAFETY PROG in Missouri, with regular state inspections and enforcement measures in place. The dam's spillway type is uncontrolled, with a width of 50 feet and a maximum discharge capacity of 483 cubic feet per second.
The risk assessment for Glenwilfern Lake Dam is considered moderate, with a Risk Management Summary pending. Although the last inspection date was in 2015, the dam's emergency action plan (EAP) status and adherence to guidelines remain unknown. With its important role in recreation and water management, continued monitoring and maintenance of Glenwilfern Lake Dam are essential to ensure the safety and sustainability of this water resource in Jefferson County, Missouri.

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 Glenwilfern Lake Dam
Where does the data for Glenwilfern 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.
