Sedimentation Pond No 15 dam
Sedimentation Pond No 15
Sedimentation Pond No 15, located in Leon, Texas, is a private earth dam structure with a primary purpose of tailings management. The dam has a height of 27 feet and a storage capacity of 92 acre-feet, serving as a vital component for controlling sediment runoff in the area. Despite not being regulated by the state, the dam is equipped with state permitting and inspection protocols to ensure its safety and functionality.
The pond, situated along the TR-LONG BRANCH river or stream, covers a surface area of 4 acres and has a drainage area of 0.2 square miles. With a high risk assessment rating of 2, it is crucial for water resource and climate enthusiasts to monitor the condition and maintenance of Sedimentation Pond No 15 to prevent any potential hazards or environmental impacts. The dam lacks a spillway and locks, emphasizing the need for strict adherence to safety measures and regular monitoring.
Although the dam's condition is currently not rated, the high-risk potential and lack of available information on emergency preparedness highlight the importance of implementing risk management measures. With no designated emergency action plan or updated contact information, it is essential for stakeholders to prioritize the safety and maintenance of Sedimentation Pond No 15 to mitigate any potential risks to the surrounding environment and communities.
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 Sedimentation Pond No 15
Where does the data for Sedimentation Pond No 15 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.
