Old Lampasas Dam dam
Old Lampasas Dam
Old Lampasas Dam, located in Travis County, Texas, stands as a testament to engineering ingenuity with its earth buttress design towering at a height of 34 feet and stretching 480 feet in length. Completed in 1984, this dam on Bull Creek not only serves as a water resource but also holds historical significance in the area. However, recent assessments have deemed its condition as poor, highlighting the need for potential maintenance and restoration efforts to ensure its longevity and functionality.
Despite its age, Old Lampasas Dam remains a regulated structure under the Texas Commission on Environmental Quality (TCEQ), with state permitting, inspection, and enforcement in place. The dam's primary purpose, classified as 'Other', reflects its multi-faceted role in water management within the region. With a storage capacity of 73 acre-feet and a drainage area of 248 square miles, the dam plays a crucial role in mitigating flood risks and managing water resources in the area, contributing to the overall resilience of the local ecosystem.
While facing challenges related to its condition assessment and hazard potential, Old Lampasas Dam continues to be monitored for risk management and emergency preparedness. With a moderate risk rating and a history of inspections, the dam serves as a focal point for both water resource enthusiasts and climate advocates, highlighting the intersection of infrastructure, environmental stewardship, and community resilience in the face of changing climate patterns.

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 Old Lampasas Dam
Where does the data for Old Lampasas 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.
