Arby Williams Dam dam
Arby Williams Dam
Arby Williams Dam, located in Dubach, Louisiana, was completed in 1980 by the USDA NRCS and serves as a crucial habitat for fish and wildlife in the area. The earth-type dam stands at a height of 23 feet, with a hydraulic height of 23 feet and a structural height of 26 feet, spanning a length of 390 feet. With a storage capacity of 65 acre-feet, the dam primarily functions as a fish and wildlife pond, while also supporting fire protection, stock, and recreational activities.
Managed by the Louisiana Department of Transportation and Development, the dam is regulated, permitted, inspected, and enforced to ensure its safety and compliance with state standards. The spillway, with a width of 80 feet, is uncontrolled and can handle a maximum discharge of 1049 cubic feet per second. Despite being classified as having a low hazard potential, the dam's condition was assessed as fair during the last inspection in July 2016, with a moderate risk level assigned.
Water resource and climate enthusiasts will appreciate the role of Arby Williams Dam in maintaining a sustainable ecosystem for fish and wildlife in the region. Its strategic location on TR-Walnut Creek, within the Vicksburg District, underscores its significance in water management and conservation efforts. With a focus on environmental stewardship and habitat preservation, the dam exemplifies the importance of balancing human needs with the protection of natural resources in a changing climate landscape.

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 Arby Williams Dam
Where does the data for Arby Williams 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.
