Chimneyhill Stormwater Holding Pond dam
Chimneyhill Stormwater Holding Pond
Located in Travis County, Texas, the Chimneyhill Stormwater Holding Pond is a private-owned structure designed to regulate stormwater runoff and provide recreational opportunities. Managed by the Texas Commission on Environmental Quality (TCEQ), this earth dam structure stands at a height of 26 feet and has a storage capacity of 40 acre-feet. With a risk assessment rating of "High (2)", the pond serves as a crucial resource in managing flood risks and maintaining water quality in the area.
Built off the Walnut Creek, the Chimneyhill Stormwater Holding Pond does not have a spillway and features one outlet gate. Although the structure was last inspected in 1991 and is not currently rated for condition assessment, it continues to play a significant role in flood control and recreation activities in the region. While the exact completion date and construction details are unavailable, the pond's primary purpose of recreation highlights its importance for both environmental conservation and community engagement.
As water resource and climate enthusiasts explore the Chimneyhill Stormwater Holding Pond, its strategic location and regulatory oversight by the TCEQ underscore its role in managing stormwater runoff and enhancing recreational opportunities. Despite its age and lack of recent inspections, the pond remains a vital asset for flood control and water quality management in Travis County. With ongoing risk management measures and potential enhancements, this structure continues to demonstrate its importance in balancing environmental protection and community recreation.
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 Chimneyhill Stormwater Holding Pond
Where does the data for Chimneyhill Stormwater Holding Pond 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.
