Jb Allen Dam dam
Jb Allen Dam
Jb Allen Dam, also known as Allen Lake, is a privately owned structure located in Clark County, Kentucky. Completed in 1970, the earth dam stands at 31 feet high and spans 300 feet in length, creating a reservoir with a storage capacity of 32.4 acre-feet. The dam is regulated by the Kentucky Division of Water and is inspected every 5 years, with a low hazard potential rating.
Situated on TR-Boone Creek in the city of Clays Ferry, Jb Allen Dam serves a primary purpose of "Other" and is classified as an earth dam type with an uncontrolled spillway. The dam's risk assessment indicates a moderate risk level (3) and its condition has not been rated. Despite its modest surface area of 3 acres, the dam plays a crucial role in managing water resources in the region and contributes to the overall climate resilience of the area.
With its historical significance dating back over 50 years, Jb Allen Dam continues to be a vital infrastructure for the community, providing water storage and flood control benefits. While the dam's condition assessment remains unknown, its operational efficiency and adherence to state regulations demonstrate a commitment to safety and environmental protection. As water resource and climate enthusiasts, the data on Jb Allen Dam underscores the importance of maintaining and monitoring critical infrastructure to ensure the sustainable management of water resources in Kentucky.

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 Jb Allen Dam
Where does the data for Jb Allen 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.
