Kentucky River Lock And Dam 1 dam
Kentucky River Lock And Dam 1
Kentucky River Lock and Dam 1, located in Carrollton, Kentucky, was completed in 1839 and serves as a vital navigation structure on the Kentucky River. Managed by the US Army Corps of Engineers, this timber crib dam stands at 35 feet in structural height with a hydraulic height of 23 feet. With a primary purpose of navigation and additional recreational benefits, the dam has a length of 462 feet and a storage capacity of 25,290 acre-feet.
Despite its low hazard potential, Kentucky River Lock and Dam 1 faces flood risk management challenges due to its limited water storage capacity and susceptibility to severe weather events. The US Army Corps of Engineers actively monitors and maintains the dam to mitigate risks, emphasizing community engagement and emergency preparedness. While the dam does not have a spillway, it can release water to control downstream water levels and maintain structural integrity. The agency works closely with local emergency managers to develop evacuation plans and update the emergency action plan regularly.
In the face of changing climate conditions and potential flood events, Kentucky River Lock and Dam 1 represents a critical infrastructure for both navigation and flood risk management. By prioritizing maintenance, monitoring conditions, and engaging with local communities, the US Army Corps of Engineers ensures the dam's resilience and readiness for any emergency situation.

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 Kentucky River Lock And Dam 1
Where does the data for Kentucky River Lock And Dam 1 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.
