J. Williams 1a dam
J. Williams 1a
J. Williams 1a is a private-owned Earth dam located in Dallas County, Alabama, specifically in the city of Orrville. Built in 1989 by the USDA NRCS, this dam serves primarily as a Fish and Wildlife Pond to support the local ecosystem. With a dam height of 9 feet and a length of 1000 feet, J. Williams 1a has a storage capacity of 87 acre-feet and covers a surface area of 13 acres. The dam is situated on TR-BEAR CANE CK., which is a tributary of the local river or stream.
Despite being classified as having a low hazard potential, J. Williams 1a is subject to moderate risk as assessed by its condition and management measures. The dam features an uncontrolled spillway with a width of 25 feet and a maximum discharge of 200 cfs. The last inspection of the dam took place in December 1989, and it has not been rated for its condition since then. While the dam has not been modified over the years, it is important to ensure regular inspections and maintenance to address any potential risks and safeguard the surrounding environment and community.
In the larger context of water resource and climate management, J. Williams 1a is a crucial infrastructure contributing to the conservation and enhancement of local fish and wildlife populations. As climate change continues to impact water resources, it is essential to monitor and maintain dams like J. Williams 1a to ensure their functionality and safety. By implementing appropriate risk management measures and conducting regular inspections, we can mitigate potential hazards and preserve the ecological balance supported by this essential water structure.

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 J. Williams 1a
Where does the data for J. Williams 1a 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.
