Nameless Valley Ranch Dam No 1 dam
Nameless Valley Ranch Dam No 1
Nameless Valley Ranch Dam No 1, located in Travis County, Texas, was completed in 1962 and stands at a height of 25 feet, with a length of 566 feet. This earth dam, with a buttress core type, serves primarily for recreational purposes and holds a maximum storage capacity of 74 acre-feet. Situated on the Palmetto Hollow stream, the dam has a normal storage capacity of 30 acre-feet, covering a surface area of 4.3 acres and draining an area of 1.12 square miles.
Managed by a private owner, the dam is regulated by the Texas Commission on Environmental Quality (TCEQ) and undergoes regular inspections to ensure its structural integrity. In 1991, the dam underwent structural modifications to enhance its safety and efficiency. With a fair condition assessment as of February 2016, the dam's risk assessment is moderate, calling for appropriate risk management measures to be in place. Despite its uncontrolled spillway type, the dam poses a moderate hazard potential and a maximum discharge capacity of 2 cubic feet per second.
Although the dam has not been associated with any federal agencies or funding, its role in providing recreational opportunities and its importance in managing water resources in the region make it a key structure for water resource and climate enthusiasts to monitor and appreciate. With its picturesque location in the scenic Nameless Valley Ranch, this dam stands as a testament to human engineering and environmental stewardship in balancing the needs of water storage and recreational activities.
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 Nameless Valley Ranch Dam No 1
Where does the data for Nameless Valley Ranch Dam No 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.
