Sediment Basin No.4 dam
Sediment Basin No.4
Sediment Basin No.4, located in Roaring Spring, Kentucky, is a Federal-owned structure designed by Bhate Environmental and managed by the US Army. Completed in 1998, this Earth dam stands at 26 feet high and serves primarily for flood risk reduction along the Tributary Casey Creek. With a storage capacity of 70 acre-feet, this basin covers a surface area of 3 acres and has a drainage area of 1 square mile.
Despite its low hazard potential, Sediment Basin No.4 undergoes regular inspections every 4 years, with the last assessment conducted in March 2017. While the condition assessment is currently unavailable, the risk assessment categorizes it as moderate (3). The dam features an uncontrolled spillway, measuring 12 feet in width, and lacks outlet gates. Although the structure has not been modified since its completion, it plays a crucial role in debris control and flood risk mitigation in the region.
For water resource and climate enthusiasts, Sediment Basin No.4 presents a fascinating case study of a Federal-owned structure designed to manage flood risks and control debris along the Tributary Casey Creek in Trigg, Kentucky. The dam, constructed by the US Army, stands as a testament to engineering excellence with its Earth design and stone buttress core types. While its primary purpose is flood risk reduction, the basin's storage capacity of 70 acre-feet and surface area of 3 acres showcase its importance in safeguarding the local community from potential hazards. As the dam continues to be monitored and inspected periodically, its role in maintaining water security and environmental safety remains crucial in the region's overall resilience to climate challenges.

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 Sediment Basin No.4
Where does the data for Sediment Basin 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.
