Lantana Regional Detention Dam dam
Lantana Regional Detention Dam
Lantana Regional Detention Dam, located in Travis County, Texas, stands as a testament to effective water resource management and climate resiliency. Constructed in 1996 by LONGARO & CLARK INC, this private-owned Earth dam is designed to manage the flow of the tributary Williamson Creek during heavy rainfall events. With a height of 28.1 feet and a length of 825 feet, the dam has a storage capacity of 189 acre-feet and a maximum discharge rate of 262 cubic feet per second.
The dam's uncontrolled spillway, with a width of 761 feet, ensures the safe release of excess water to prevent overflow and flooding. Regular inspections have deemed the dam's condition as fair, with a moderate risk assessment rating. The Texas Commission on Environmental Quality (TCEQ) regulates the dam's operations, inspections, and enforcement, highlighting the commitment to safety and environmental stewardship in the region.
Overall, Lantana Regional Detention Dam serves as a vital infrastructure asset in managing water resources and mitigating flood risks in the area. Its strategic design and regulatory oversight demonstrate a proactive approach to climate resilience and sustainable water management practices, making it a standout example for water resource and climate enthusiasts alike.
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 Lantana Regional Detention Dam
Where does the data for Lantana Regional Detention 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.
