Leaky Lake Dam dam
Leaky Lake Dam
Leaky Lake Dam, located in Washington, Missouri, is a private Earth dam primarily used for recreation purposes. With a height of 34 feet and a storage capacity of 200 acre-feet, this dam is situated on a tributary to St. Johns River. Despite being state-regulated, Leaky Lake Dam has not undergone recent inspections or condition assessments, and its hazard potential is deemed low.
The dam, managed by a private owner, is categorized as a Buttress dam and covers a surface area of 11 acres. Although it has not been modified in recent years, its emergency action plan status remains unknown. The surrounding area has a drainage area of 180 acres, with a normal storage capacity of 120 acre-feet. While the dam is not considered a high-risk structure, its condition assessment has not been rated, indicating a need for further evaluation and maintenance to ensure safety and longevity.
For water resource and climate enthusiasts, Leaky Lake Dam presents an intriguing case study of a privately-owned recreational dam with limited regulatory oversight. Its location in Franklin County, Missouri, offers a unique opportunity to explore the intersection of dam management, environmental conservation, and public safety. With its low hazard potential and unassessed condition, this dam serves as a reminder of the importance of regular inspections and maintenance to prevent potential risks and ensure the sustainable use of water resources in the region.

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 Leaky Lake Dam
Where does the data for Leaky 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.
