Sediment Pond 17b dam
Sediment Pond 17b
Sediment Pond 17b, located in Jourdanton, Texas, is a privately owned Earth dam structure with a primary purpose of serving as a sediment pond. Completed in 2000, this dam has a height of 22 feet and a length of 2395 feet, providing a storage capacity of 227 acre-feet. With a surface area of 23.8 acres and a drainage area of 0.63 square miles, Sediment Pond 17b plays a crucial role in managing water resources in the region.
Although not regulated by the state, Sediment Pond 17b is inspected by the Mine Safety and Health Administration, ensuring its structural integrity and safety. The dam features an uncontrolled spillway with a width of 50 feet and an outlet gate for water discharge. With a moderate risk assessment rating, Sediment Pond 17b is deemed to have a manageable risk level, highlighting the importance of continued monitoring and maintenance to prevent any potential hazards or issues.
Overall, Sediment Pond 17b stands as a vital water management infrastructure in Atascosa County, Texas, contributing to sediment control and water storage in the area. Its design and construction reflect the commitment to sustainable water resource management, while the regular inspections by relevant agencies ensure its safety and reliability for the community and surrounding environment.

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 Sediment Pond 17b
Where does the data for Sediment Pond 17b 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.
