Summary
This private dam, with a height of 33 feet and a length of 2650 feet, has a storage capacity of 5064 acre-feet. The dam is situated on HURDS PASS DRAW and is regulated by the Texas Commission on Environmental Quality (TCEQ).
The dam features an uncontrolled spillway with a width of 550 feet and has four outlet gates, three of which are uncontrolled and one valve-controlled. While the dam's hazard potential is not available, its condition assessment is not rated. The risk assessment for the dam is moderate (3), indicating a certain level of risk associated with the structure. Despite the last inspection date dating back to 1992, the dam is equipped to provide necessary protection and resources to the surrounding area in case of emergencies.
Overall, Big Charlie Tank Dam stands as a vital resource for the region, ensuring water supply for firefighting, livestock, and recreational activities. The dam's historical significance, combined with its structural features and regulatory oversight, underscores its importance in water resource management and climate resilience efforts in Culberson, Texas.

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.
