Duval County Ranch Lloyd Tank Dam dam
Duval County Ranch Lloyd Tank Dam
The Duval County Ranch Lloyd Tank Dam, located in Three Rivers, Texas, is a private dam designed by the USDA NRCS for the primary purpose of serving as a Fish and Wildlife Pond. Completed in 1969, this Earth dam stands at a height of 15 feet and has a length of 950 feet, with a storage capacity of 156 acre-feet. The dam is situated on the TR-CHARAMUSCA CREEK and falls under the jurisdiction of the Fort Worth District of the US Army Corps of Engineers.
This dam plays a crucial role in providing fire protection, stock water, and habitat for small fish, in addition to supporting wildlife in the area. Despite its high risk assessment level of 2, the dam is currently rated as "Not Available" in terms of hazard potential and "Not Rated" in condition assessment. With no spillway and limited outlet gates, the dam requires regular inspection and maintenance to ensure its structural integrity and safety for the surrounding environment.
Water resource and climate enthusiasts will find the Duval County Ranch Lloyd Tank Dam to be a fascinating example of a privately owned structure that serves multiple purposes in enhancing the local ecosystem. Its design, construction, and ongoing management provide valuable insights into the intersection of human infrastructure with natural resources, highlighting the importance of sustainable water management practices in maintaining the delicate balance of ecosystems in the region.

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 Duval County Ranch Lloyd Tank Dam
Where does the data for Duval County Ranch Lloyd 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.
