Shoaf dam
Shoaf
Shoaf, a privately owned dam located in Carroll, Tennessee, serves primarily for irrigation purposes. Built in 1937, this earth dam stands at a hydraulic height of 15.9 feet and spans a length of 490 feet along Lick Creek. With a maximum storage capacity of 81 acre-feet and a normal storage level of 64 acre-feet, Shoaf covers a surface area of 10.1 acres and drains a watershed area of 0.17 square miles.
Although classified as having a low hazard potential and a moderate risk level, Shoaf has not been rated for its current condition. This dam operates with uncontrolled spillways and lacks outlet gates. The last inspection occurred in November 2018, with a scheduled inspection frequency of every 5 years. While the dam has not been modified in recent years, there are no emergency action plans (EAPs) in place or inundation maps prepared for potential risk scenarios.
Given its historical significance and functional importance for irrigation in the region, Shoaf presents an interesting case study for water resource and climate enthusiasts. With its unique design features and operational characteristics, this dam offers valuable insights into the management and maintenance of infrastructure in the face of changing environmental conditions and evolving regulatory standards. Explore the rich history and practical implications of Shoaf to gain a deeper understanding of how water resources are harnessed and protected in a dynamic natural landscape like Tennessee.

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 Shoaf
Where does the data for Shoaf 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 Low 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.
