Greenup Locks And Dam dam
Greenup Locks And Dam
Greenup Locks and Dam, located on the Ohio River in Greenup, Kentucky, is a federal structure managed by the US Army Corps of Engineers. Completed in 1962, this concrete dam serves multiple purposes including navigation, hydroelectric power generation, and recreation. With a structural height of 78 feet and a length of 1622 feet, Greenup Locks and Dam has a significant hazard potential and a very high risk assessment rating (1).
The dam features a controlled spillway with a width of 900 feet and two locks, each 1200 feet long and 110 feet wide. A key feature of the dam is its ability to manage water levels upstream and downstream, as well as to relieve pressure to maintain structural integrity during severe weather events. The US Army Corps of Engineers closely monitors the dam's condition, implements risk management measures, and collaborates with local emergency managers to ensure preparedness in case of a dam-related emergency.
Despite the risks associated with dam operations, the US Army Corps of Engineers actively engages in maintenance and repair activities to ensure the proper functioning of Greenup Locks and Dam. The agency also emphasizes public awareness and emergency planning, highlighting the importance of proactive measures to mitigate potential hazards and ensure the safety of surrounding communities.

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 Greenup Locks And Dam
Where does the data for Greenup Locks And 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.
