John Mitchell No.1 dam
John Mitchell No.1
John Mitchell No.1 in Demopolis, Alabama, is a private fish and wildlife pond designed by the USDA NRCS in 1986. The dam, primarily used for fish and wildlife purposes, stands at a height of 11 feet and has a length of 2300 feet, providing a storage capacity of 94 acre-feet. The spillway, with a width of 55 feet, is uncontrolled, and the dam has a low hazard potential with a moderate risk assessment rating.
Located in Hale County, Alabama, the John Mitchell No.1 dam on the TR-GERMAN GK. river is managed by private owners and has not been regulated or inspected by state agencies. Despite being constructed over three decades ago, the dam's condition assessment remains unrated, with no recent inspections or risk management measures in place. The surrounding area has a drainage area of 0.08 square miles and can discharge a maximum of 115 cubic feet per second.
For water resource and climate enthusiasts, John Mitchell No.1 offers a glimpse into the design and maintenance of private dams for fish and wildlife conservation. With its low hazard potential and moderate risk assessment, this earth dam presents an opportunity to explore the intersection of water management, ecological preservation, and infrastructure development in rural Alabama. As the dam continues to provide habitat for local wildlife, its role in sustaining the surrounding ecosystem warrants further attention and study in the context of changing climate patterns and water resource management practices.
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.

About John Mitchell No.1
Where does the data for John Mitchell 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.
