Marshall Mccay Lake Dam dam
Marshall Mccay Lake Dam
Marshall Mccay Lake Dam, located in the Elvesta Community of Blount, Alabama, is a private earth dam built in 1951 primarily for recreational purposes. The dam stands at a hydraulic height of 9 feet and a structural height of 16 feet, with a length of 523 feet. It has a high hazard potential and a normal storage capacity of 101 acre-feet, with a maximum storage of 215 acre-feet. The dam is situated on Hogeland Creek and is not regulated by the state.
Despite not being state-regulated, Marshall Mccay Lake Dam plays a crucial role in providing recreational opportunities for the local community. The dam's close proximity to the city of ELVESTA COMMUNITY makes it a popular spot for fishing, boating, and other water-related activities. With a maximum discharge capacity of 988 cubic feet per second, the dam ensures the safety and enjoyment of visitors while also serving as a key component of the region's water resource management.
While its condition is currently not rated, Marshall Mccay Lake Dam remains a significant landmark in the area, attracting water resource and climate enthusiasts alike. As a private structure with no state jurisdiction, the dam represents a unique intersection of human intervention and natural landscape, highlighting the importance of responsible management and maintenance of water resources in the face of evolving climate challenges. Its presence on Hogeland Creek contributes to the overall ecosystem health and serves as a reminder of the delicate balance between human needs and environmental sustainability.

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 Marshall Mccay Lake Dam
Where does the data for Marshall Mccay Lake 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 High 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.
