Maryland Farms Det # 2 dam
Maryland Farms Det # 2
Maryland Farms Detention #2 is a private earth dam located in Franklin, Tennessee, along the Tributary of Little Harpeth River. Built in 1983, the dam stands at a hydraulic height of 6.1 feet and a structural height of 18.9 feet, with a length of 635 feet. It has a normal storage capacity of 11 acre-feet and a maximum storage capacity of 81 acre-feet, serving a drainage area of 0.54 square miles.
The dam is under the regulatory authority of the Tennessee Safe Dams Program, which ensures that the structure is permitted, inspected, and enforced in compliance with state regulations. Despite being designated as having a high hazard potential, the dam's condition assessment in May 2020 reported it as satisfactory. In case of emergencies, however, there is no Emergency Action Plan (EAP) prepared for the dam, raising some concerns regarding its risk management measures and preparedness.
With its critical role in flood control and water resource management, Maryland Farms Detention #2 serves as a vital infrastructure in the region. Its location in Williamson County highlights the importance of maintaining and monitoring the dam to ensure the safety of the surrounding community and the stability of the water supply in the area. Climate enthusiasts and water resource experts alike can appreciate the significance of this structure and the need for ongoing vigilance in its oversight and maintenance.
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 Maryland Farms Det # 2
Where does the data for Maryland Farms Det # 2 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.
