Hidden Springs Dam dam
Hidden Springs Dam
Hidden Springs Dam, located in Bexar, Texas, along the TR-Salado Creek, is a private earth dam primarily used for recreation. Designed by PFA and Associates, this dam stands at a height of 25 feet and has a storage capacity of 46 acre-feet. While its purpose is for recreational activities, the dam is regulated by the Texas Commission on Environmental Quality (TCEQ) and undergoes regular inspections and enforcement to ensure safety and compliance.
Despite its relatively small structure, Hidden Springs Dam poses a high risk potential, with a hazard rating of 2 out of 5. The condition assessment of the dam is currently not rated, and there is limited information on its emergency action plan and risk management measures. With no spillway and limited information on its construction date and modifications, water resource and climate enthusiasts may find Hidden Springs Dam to be a noteworthy site for further study and monitoring, given its importance in the local water infrastructure.
As part of the Galveston District, Hidden Springs Dam's unique design as a buttress earth dam adds to its appeal for those interested in hydraulic engineering and dam construction. With a lack of detailed information on its inspection dates and emergency preparedness, there is a potential for further research and assessment to better understand the dam's structural integrity and potential impacts on the surrounding environment and community. For water resource and climate enthusiasts, Hidden Springs Dam presents an intriguing case study in the intersection of recreational infrastructure and water management in Texas.

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 Hidden Springs Dam
Where does the data for Hidden Springs 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.
