About this dam

Tom Miller Dam

Tom Miller Dam, located on the Colorado River in Travis County, Texas, serves as a vital water resource for the region. Completed in 1939, this concrete gravity dam stands at a height of 85 feet and has a length of 1395 feet. With a maximum storage capacity of 115,404 acre-feet and a normal storage level of 25,200 acre-feet, the dam plays a crucial role in providing irrigation, recreation, and water supply to the surrounding areas.

Managed by the local government and regulated by the Texas Commission on Environmental Quality (TCEQ), Tom Miller Dam also serves a primary purpose as a hydroelectric power source. The dam features outlet gates for controlled water release, as well as a spillway width of 1002 feet. Despite being modified in 2005 for foundation and structural improvements, the dam is assessed to be in satisfactory condition as of August 2015, ensuring its continued functionality and safety for the community.

With its impressive hydraulic and structural height, Tom Miller Dam stands as a testament to efficient water resource management and climate resilience efforts in Texas. This landmark structure not only provides essential services for irrigation and water supply but also contributes significantly to the local economy and environment. As a key player in the region's water management infrastructure, Tom Miller Dam continues to play a crucial role in sustaining the Colorado River ecosystem and supporting the diverse needs of its stakeholders.

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.

FAQ

About Tom Miller Dam

Where does the data for Tom Miller 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.
