About this dam

Lakewood

Lakewood is a private dam located in Stewart, Tennessee, specifically in the city of Goodlettsville. Built in 1976, this earth dam stands at a structural height of 29 feet and has a hydraulic height of 21.8 feet. With a primary purpose of recreation, Lakewood also serves the important functions of flood risk reduction. The dam has a normal storage capacity of 66 acre-feet and a maximum storage capacity of 132 acre-feet, covering a surface area of 7.6 acres and draining an area of 0.45 square miles.

Managed by the Tennessee Safe Dams Program, Lakewood is regulated, permitted, inspected, and enforced by the state. The dam is categorized as having a high hazard potential but is currently assessed as being in satisfactory condition as of the most recent inspection in March 2021. While the risk assessment for the dam is moderate, there are no specific risk management measures or inundation maps prepared at this time. Despite its moderate risk level, the dam's condition is deemed satisfactory, providing a safe recreational environment for visitors and serving as a critical flood risk reduction structure in the area.

Lakewood's location along Tribwalkers Creek and its proximity to the Nashville District of the US Army Corps of Engineers make it a significant part of the region's water resource management infrastructure. With its uncontrolled spillway type and lack of outlet gates, the dam poses a potential risk that is being carefully monitored and managed. As a key player in the region's water resource and climate resilience efforts, Lakewood continues to be an important structure for both recreation and flood risk reduction in the area.

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.

FAQ

About Lakewood

Where does the data for Lakewood 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.
