Mary Ann Drake dam
Mary Ann Drake
Mary Ann Drake, also known as Lady Ann Lake, is a privately owned fish and wildlife pond located in Triana, Alabama. Designed by the USDA NRCS in 1956, this earth dam stands at a height of 8 feet and has a length of 1700 feet. With a storage capacity of 736 acre-feet, it serves as a habitat for wildlife and a recreational spot for enthusiasts in the area. The dam is situated on Betts Spring Branch in Madison County, Alabama, and is managed by the Natural Resources Conservation Service.
Despite being classified as having a low hazard potential, Mary Ann Drake plays a crucial role in maintaining the ecological balance of the surrounding area. Its primary purpose is to support fish and wildlife populations, with an emphasis on conservation and recreation. With a drainage area of 2.19 square miles and a maximum discharge rate of 683 cubic feet per second, the dam serves as a vital resource for water management in the region.
Although Mary Ann Drake has not been rated for its current condition, it continues to be a focal point for water resource and climate enthusiasts in the area. With a moderate risk assessment level of 3, the dam requires ongoing monitoring and management to ensure its continued safety and functionality. As part of the larger ecosystem, this privately owned structure highlights the importance of sustainable water resource management for both wildlife and human communities.

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 Mary Ann Drake
Where does the data for Mary Ann Drake 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.
