Goldthwaite Water Supply Reservoir dam
Goldthwaite Water Supply Reservoir
Goldthwaite Water Supply Reservoir, located in Mills County, Texas, was completed in 1960 and is owned by the local government. The primary purpose of this earth dam structure is to provide water supply, with a maximum storage capacity of 115 acre-feet. The reservoir is regulated by the Texas Commission on Environmental Quality (TCEQ) and undergoes regular inspections, maintenance, and enforcement to ensure its safety and functionality.
With a height of 20 feet and a length of 6345 feet, Goldthwaite Water Supply Reservoir sits off the Colorado River and does not have a spillway. Despite being classified as high risk (2), the condition of the dam has not been rated. It is important to note that the emergency action plan (EAP) for the reservoir is not available, indicating potential gaps in preparedness for any unforeseen events. While the dam's hazard potential is not specified, its critical role in providing water supply to the region underscores the importance of ongoing risk management measures.
Overall, Goldthwaite Water Supply Reservoir serves as a crucial water resource for the community, highlighting the intersection between water supply infrastructure and climate resilience. As climate change impacts continue to affect water availability and quality, ensuring the safety and efficiency of such reservoirs becomes increasingly vital. The data provided offers insights into the structure's design, regulatory oversight, and risk assessment, pointing towards the need for continued monitoring and maintenance to safeguard this essential resource for future generations.

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 Goldthwaite Water Supply Reservoir
Where does the data for Goldthwaite Water Supply Reservoir 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.
