Summary
With a height of 9 feet and a length of 1000 feet, this earth dam provides a storage capacity of 107 acre-feet and covers a surface area of 17 acres. Despite not having a spillway, the dam plays a vital role in fire protection, stock maintenance, and small fish pond management in addition to its primary purpose of supporting fish and wildlife.
Managed by a private owner, the Duval County Ranch Crump Tank Dam is inspected and permitted by the state of Texas. With a hazard potential of "Not Available" and a risk assessment of "High (2)", the dam's condition is not currently rated. While there are no outlet gates, the dam is designed with a buttress core type and rests on an unlisted/unknown foundation. This structure, situated along the Ygnacio Creek, represents a significant contribution to water resource management in the region and underscores the importance of sustainable practices in maintaining its integrity for future generations.
Enthusiasts of water resources and climate in Duval County, Texas, will find the Duval County Ranch Crump Tank Dam to be a fascinating case study in dam construction and maintenance. As a key component in the local ecosystem, this earth dam not only provides essential water storage for fish and wildlife but also serves multiple purposes including fire protection and stock management. With its high risk assessment, the dam highlights the importance of regular inspections and risk management measures to ensure its continued safety and efficacy in supporting the surrounding environment.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
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. Investigations and studies are necessary.
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.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams 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, environment 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.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
