Ac Skannal No 1 dam
Ac Skannal No 1
Ac Skannal No 1, also known as Skannal Dam, is a private-owned structure located in Bossier, Louisiana, specifically in Taylor Town. It was designed by USDA NRCS and completed in 1963 with a primary purpose of serving as a Fish and Wildlife Pond. This earth dam has a height of 14 feet, a hydraulic height of 11 feet, and a structural height of 20 feet, with a length of 775 feet. It has a storage capacity of 150 acre-feet, with a normal storage of 80 acre-feet and a surface area of 20 acres, making it an essential resource for fish and wildlife conservation, irrigation, and recreation in the region.
The Ac Skannal No 1 dam is regulated and inspected by the Louisiana Department of Transportation and Development, ensuring its compliance with state regulations and safety standards. With a low hazard potential and a fair condition assessment as of the last inspection in July 2017, the dam poses a moderate risk (3) according to the risk assessment. The spillway type is uncontrolled, with a width of 29 feet. While there are no associated locks, the dam has a drainage area of 0.39 square miles and a maximum discharge capacity of 791 cubic feet per second, further highlighting its importance in managing water resources in the area.
Overall, Ac Skannal No 1 serves as a vital infrastructure for water resource management and conservation in Bossier, Louisiana. With its primary purpose of supporting fish and wildlife activities, as well as providing irrigation and recreational opportunities, this earth dam plays a crucial role in maintaining the ecological balance and water supply in the region. Its regulated status, low hazard potential, and moderate risk assessment emphasize the importance of regular inspections and maintenance to ensure the continued safety and functionality of the dam for the benefit of the community and the environment.

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 Ac Skannal No 1
Where does the data for Ac Skannal 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 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.
