Upper Green River Frs No 4 dam
Upper Green River Frs No 4
Upper Green River FRS No 4, located in Lincoln County, Kentucky, is a critical flood risk reduction structure designed by the Soil Conservation Service of USDA/NRCS and completed in 1959. This earth-type dam stands at 45 feet tall with a length of 400 feet, providing storage of 229 acre-feet and serving the primary purpose of flood risk reduction along the South Fork Green River. Despite its low hazard potential, the dam has a moderate risk assessment rating of 3, indicating the need for ongoing monitoring and management.
Managed by the Kentucky Division of Water, Upper Green River FRS No 4 is regulated, permitted, inspected, and enforced by state agencies to ensure its structural integrity and safety. The dam has not been rated for condition assessment, and emergency action preparedness measures are not currently documented. However, with a regular inspection frequency of 5 years, the dam remains a vital component in the flood risk reduction strategy for the area. Its location in SOUTH FORK and association with the Nashville District of the USACE highlight its significance in water resource management and climate resilience efforts in the region.
Water resource and climate enthusiasts will appreciate the engineering and design details of Upper Green River FRS No 4, as well as its contribution to mitigating flood risks along the South Fork Green River. The dam's historical construction and ongoing regulatory oversight by the Kentucky Division of Water underscore the importance of effective flood control infrastructure in safeguarding communities and ecosystems. As a key component in the region's water management system, Upper Green River FRS No 4 serves as a reminder of the critical role of sustainable water resource practices in adapting to changing climate conditions and ensuring resilience in the face of environmental challenges.
Dam data reference
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 Upper Green River Frs No 4
Where does the data for Upper Green River Frs No 4 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.
