4th July Tank Dam dam
4th July Tank Dam
Located in Zavala, Texas, the 4th July Tank Dam is a privately owned structure primarily used for fire protection, stock, or as a small fish pond. Built in 1973, this earth dam stands at a height of 10 feet and has a length of 900 feet, with a storage capacity of 72 acre-feet. Despite its modest size, the dam serves an important purpose in the region, providing essential water resources for local residents and wildlife.
Situated along the TR-CHAPARROSA CREEK, the 4th July Tank Dam is managed by private owners and falls under the jurisdiction of the state of Texas. While it does not have a spillway, the dam features one outlet gate for water release. With a risk assessment rating of High (2), there is a need for regular inspections and potential risk management measures to ensure the safety and efficiency of the structure. Water resource and climate enthusiasts will find the history and specifications of the 4th July Tank Dam fascinating, as it plays a crucial role in supporting the surrounding ecosystem and community.
As a key feature in the Fort Worth District of Texas, the 4th July Tank Dam stands as a testament to the importance of water management and conservation in the region. With its unique design and purpose, this earth dam serves as a vital resource for maintaining water levels and supporting various activities in the area. Despite its relatively small size, the dam's impact on the local environment and economy is significant, making it a valuable asset for water resource and climate enthusiasts to study and appreciate.

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 4th July Tank Dam
Where does the data for 4th July Tank 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.
