Upper Green River Frs No 2 dam
Upper Green River Frs No 2
Upper Green River FRS No 2 is a flood risk reduction structure located in Jumbo, Kentucky along the Green River. Built in 1959 by the Soil Conservation Service, USDA/NRCS, this earth dam stands at a height of 40 feet and spans 380 feet in length. With a storage capacity of 104.8 acre-feet, it serves the primary purpose of flood risk reduction, protecting the surrounding area from potential inundation.
Managed by the KY Division of Water, this dam is regulated, permitted, inspected, and enforced by state authorities to ensure its structural integrity and functionality. Despite being classified as having a low hazard potential, the risk assessment for Upper Green River FRS No 2 is moderate (3), highlighting the importance of ongoing monitoring and maintenance. While the condition assessment is currently not rated, the last inspection in 2013 indicated that the structure requires periodic evaluations every 5 years to uphold its effectiveness in mitigating flood risks.
With its critical role in safeguarding the local community from potential flooding, Upper Green River FRS No 2 stands as a testament to the collaborative efforts between federal and state agencies in managing water resources and climate-related challenges. As water resource and climate enthusiasts, understanding the design, operation, and risk assessment of such structures is paramount in ensuring the resilience of our infrastructure against natural disasters.
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 2
Where does the data for Upper Green River Frs No 2 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.
