Slurry Impoundment No.1 dam
Slurry Impoundment No.1
Slurry Impoundment No.1, located in Sayre, Alabama, is a private water supply facility with a dam height of 19 feet and a storage capacity of 600 acre-feet. Despite being non-regulated by the state, the Mine Safety and Health Administration oversees its operations and inspections, ensuring the safety and integrity of the structure. With a low hazard potential, the impoundment serves its primary purpose of water supply to the surrounding area.
Although details about the dam's construction date and condition assessment are not available, the last inspection conducted in January 2004 deemed it to have a low hazard potential. While the impoundment lacks an Emergency Action Plan and risk assessment, the Mine Safety and Health Administration's oversight helps mitigate potential risks and ensures the facility's compliance with safety guidelines. Its location in Jefferson County, Alabama, further underscores the importance of maintaining proper regulatory oversight for the protection of the local water resources.
As a vital water supply infrastructure in the region, Slurry Impoundment No.1 plays a crucial role in meeting the water needs of the community. While its risk assessment and emergency preparedness could be further enhanced, the oversight provided by the Mine Safety and Health Administration helps maintain the impoundment's safety and operational standards. Continued monitoring and adherence to regulatory guidelines will be essential in safeguarding this important water resource for the future.

About Slurry Impoundment No.1
Where does the data for Slurry Impoundment No.1 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 below 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.
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.
