South Flat Top Dam dam
South Flat Top Dam
South Flat Top Dam, located in Bosque, Texas, is a private earth dam completed in 1966 for the primary purpose of water supply. Standing at 25 feet high with a length of 1190 feet, this dam has a storage capacity of 300 acre-feet, with a normal storage level of 137 acre-feet. Situated on the TR-North Bosque River, the dam has a hazard potential classified as "Not Available" and a risk assessment rating of "High (2)", indicating the importance of its maintenance and monitoring.
Despite being privately owned, South Flat Top Dam is regulated by the state and undergoes regular inspections. The dam does not have a spillway and features a buttress core type with one outlet gate. With a surface area of 18 acres, this dam plays a crucial role in water resource management in the region. Its location in the Fort Worth District highlights its significance in the overall water infrastructure of Texas.
For water resource and climate enthusiasts, South Flat Top Dam serves as a fascinating example of earth dam engineering for water supply. Its presence on the TR-North Bosque River adds to the hydrological landscape of the area and underscores the importance of proper maintenance and risk management for dam structures. As a key component in the water supply system of Bosque, Texas, South Flat Top Dam represents the intersection of human intervention and natural resources in the ongoing effort to secure water for communities in the region.

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 South Flat Top Dam
Where does the data for South Flat Top Dam 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 Not Available 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.
