Sedimentation Pond No 11 Stage 1 dam
Sedimentation Pond No 11 Stage 1
Sedimentation Pond No 11 Stage 1 in Leon, Texas, is a private earth dam designed for tailings storage on Red Hollow Creek. With a storage capacity of 192 acre-feet and a surface area of 7 acres, this pond serves as a crucial infrastructure for managing sedimentation in the area. The dam stands at a height of 20 feet, with a hydraulic height matching that measurement, ensuring effective containment of tailings materials.
Despite being privately owned, this sedimentation pond is regulated by the state, with permitting and inspection requirements in place to ensure its structural integrity and environmental impact. The risk assessment for this dam indicates a high risk level, highlighting the importance of proper maintenance and management measures. While the condition assessment is currently marked as "Not Rated," ongoing evaluations and adherence to regulatory guidelines are essential for ensuring the safety and efficiency of Sedimentation Pond No 11 Stage 1 for the long term.
Located within the Fort Worth District and under the jurisdiction of the state of Texas, Sedimentation Pond No 11 Stage 1 plays a vital role in managing tailings and sedimentation along Red Hollow Creek. With its primary purpose being tailings storage, this earth dam with buttress core types represents a key infrastructure for water resource and climate enthusiasts to monitor and support. As efforts continue to assess and address the risks associated with this dam, it remains a focal point for environmental stewardship and sustainable water management practices 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 Sedimentation Pond No 11 Stage 1
Where does the data for Sedimentation Pond No 11 Stage 1 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.
