Willowbrook Lake Dam dam
Willowbrook Lake Dam
Willowbrook Lake Dam, located in Stone County, Missouri, is a privately owned structure that holds back water from the tributary Roark Creek. With a significant hazard potential and a buttress core type, this dam stands at a height of 38 feet and has a hydraulic height of 34.73 feet. Its purpose and dam type are unspecified, but it boasts a normal storage capacity of 96.9 acre-feet and covers a surface area of 8.37 acres.
Managed by the DAM AND RESERVOIR SAFETY PROG in Missouri, Willowbrook Lake Dam is regulated, permitted, inspected, and enforced by state agencies. Despite its satisfactory condition assessment, the dam lacks an emergency action plan (EAP) and updated contact information. The risk assessment, DSAC assignment, and risk management measures are also missing, indicating potential gaps in emergency preparedness and response.
Overall, Willowbrook Lake Dam presents an intriguing case study for water resource and climate enthusiasts, showcasing the complex interplay between private ownership, state regulation, and dam safety. As a significant hazard structure with a satisfactory condition assessment, the absence of key emergency preparedness measures raises questions about the potential risks and vulnerabilities associated with this dam. Further research and assessment are needed to ensure the safety and resilience of Willowbrook Lake Dam in the face of changing environmental conditions and increasing pressures on water resources.

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 Willowbrook Lake Dam
Where does the data for Willowbrook 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 Significant 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.
