Denman Park Dam dam
Denman Park Dam
Denman Park Dam in San Antonio, Texas, is a vital local government-owned structure regulated by the Texas Commission on Environmental Quality (TCEQ). Designed by Freese and Nichols, this Earth-type dam with a buttress core stands at a height of 20 feet and stretches 490 feet in length. Its primary purpose is categorized as 'Other', serving as a critical component along the TR-San Antonio river.
With a storage capacity of 19 acre-feet and a maximum discharge of 90 cubic feet per second, Denman Park Dam plays a crucial role in managing water resources in the area. The dam's spillway, an uncontrolled type, has a width of 19 feet to handle excess water flow during heavy rainfall events. Despite its moderate hazard potential, the dam's condition is assessed as satisfactory, with regular inspections conducted every five years to ensure its structural integrity and functionality.
The risk management measures for Denman Park Dam are currently not specified, but its risk assessment indicates a moderate level of risk. With a history of modifications in 2016 focusing on hydraulic improvements, the dam continues to be a significant asset for water management in the region, highlighting the importance of sustainable infrastructure for climate enthusiasts and water resource experts alike.
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 Denman Park Dam
Where does the data for Denman Park 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.
