Green River Lock And Dam 3 dam
Green River Lock And Dam 3
Green River Lock and Dam 3, also known as Rochester Dam, is a federal structure located in Kentucky along the Green River. Completed in 1836, the dam serves primarily for navigation purposes and is operated and managed by the US Army Corps of Engineers. With a hydraulic height of 27 feet and a dam length of 410 feet, it has a low hazard potential and is deemed to have a high risk assessment due to its limited capacity to store water, which may lead to dam releases during severe weather events.
To manage the flood risks associated with the dam, the US Army Corps of Engineers continuously monitors its condition, prioritizes maintenance activities, and collaborates with local emergency managers to develop emergency action plans. Regular maintenance and repairs are conducted to ensure the dam's structural integrity and functionality. Despite the risks involved, the Corps works diligently to mitigate potential issues and maintain public safety, emphasizing the importance of preparedness and awareness in the event of a dam-related emergency.
Green River Lock and Dam 3 serves as a critical component in the water resource management of the area, highlighting the need for ongoing risk management measures and proactive community engagement. As climate change impacts intensify, the resilience and effectiveness of such structures become paramount in ensuring the sustainable use of water resources and mitigating potential hazards.

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 Green River Lock And Dam 3
Where does the data for Green River Lock And Dam 3 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.
