Woodhaven dam
Woodhaven
Woodhaven is a state-regulated dam located in Dickson, Tennessee, specifically in the city of White Oak Flats. Built in 1935, this earth dam stands at a height of 40 feet with a hydraulic height of 30 feet and a length of 550 feet. It holds a maximum storage capacity of 1400 acre-feet, with a normal storage of 800 acre-feet, covering a surface area of 50 acres and draining an area of 4.75 square miles.
Managed by the Tennessee Safe Dams Program, Woodhaven has a high hazard potential but is currently in satisfactory condition as of the last inspection in December 2020. The dam operates an uncontrolled spillway type and lacks outlet gates. Although no associated structures are present, its location along the Will Hall Creek poses a moderate risk level (3). The dam is not under the authority of the US Army Corps of Engineers and has not undergone significant modifications in recent years.
For water resource and climate enthusiasts, Woodhaven presents a noteworthy case of a state-regulated dam in Tennessee with historical significance dating back to the 1930s. With its high hazard potential and moderate risk assessment, continued monitoring and maintenance are crucial to ensure the safety and integrity of this earth dam. As part of the larger network of dams in the area, Woodhaven plays a key role in water management and flood control along the Will Hall Creek, highlighting the importance of responsible dam operation and regulation in safeguarding local communities and ecosystems.

About Woodhaven
Where does the data for Woodhaven 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 below 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.

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.
