Lake Marian dam
Lake Marian
Lake Marian, also known as Margerita Craig Dam, is a private recreational lake located in Sevier, Tennessee. Built in 1958 by the USDA NRCS, this earth dam stands at a structural height of 51.4 feet and has a hydraulic height of 43.6 feet. With a storage capacity of 121 acre-feet, the dam serves primarily for recreation purposes and is regulated by the Tennessee Safe Dams Program.
The dam's hazard potential is rated as high, with a moderate risk assessment score of 3. Despite not being conditionally assessed, the dam is regularly inspected by state authorities and meets state regulatory standards. The dam's spillway type is uncontrolled, and it has no outlet gates or associated lock structures. The surrounding area, including Cove Creek, benefits from the lake's surface area of 5.1 acres and a drainage area of 0.14 square miles.
Lake Marian offers a serene escape for water resource and climate enthusiasts in WEAR VALLEY, with its picturesque setting and recreational opportunities. As a privately-owned water body, the dam's importance lies in providing a safe and enjoyable environment for visitors while adhering to state regulations and inspection protocols. With its rich history and natural beauty, Lake Marian stands as a valuable asset in the Tennessee landscape, contributing to the region's water resource management and environmental sustainability efforts.
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 Lake Marian
Where does the data for Lake Marian 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.
