Green River Sand & Gravel Dam dam
Green River Sand & Gravel Dam
Green River Sand & Gravel Dam, located in Hart County, Kentucky, is a privately owned structure regulated by the Kentucky Division of Water. Built in 1963, this earth dam stands at a height of 30 feet and spans 530 feet in length, providing a storage capacity of 80 acre-feet. While the dam's primary purpose is listed as "Other," its low hazard potential and moderate risk assessment suggest that it plays a crucial role in managing water resources in the area.
Despite its age, Green River Sand & Gravel Dam has not been rated for its condition assessment, indicating a need for further evaluation and maintenance. The dam features an uncontrolled spillway type and has a relatively low inspection frequency of 5 years. With a risk management measure of moderate (3), it is essential for water resource and climate enthusiasts to monitor the safety and effectiveness of this structure to ensure its continued functionality in the face of changing environmental conditions.
As a key component of water resource management in the region, Green River Sand & Gravel Dam serves as a reminder of the importance of dam safety and maintenance. With its location in a rural area and limited associated structures, this dam presents an opportunity for stakeholders to collaborate on enhancing its resilience to potential hazards. By staying informed and engaged with the regulatory agencies overseeing its operation, enthusiasts can contribute to the sustainable use of this vital water infrastructure for years to come.

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 Sand & Gravel Dam
Where does the data for Green River Sand & Gravel 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 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.
