Summary
It has a storage capacity of 300 acre-feet and a normal storage of 180 acre-feet, serving as a crucial water resource for the area.
The dam is situated on an unnamed tributary of Beason Creek and is under the jurisdiction of the Galveston District. With a spillway width of 79 feet and uncontrolled outlet gates, the dam has a moderate risk assessment rating. While it is not currently rated for its condition, the dam is inspected regularly by state authorities, ensuring its safety and functionality for the surrounding community and ecosystem. For water resource and climate enthusiasts, G3gc Ranch Dam represents a vital infrastructure supporting sustainable water management in the region.
As an essential part of the local water infrastructure, G3gc Ranch Dam plays a significant role in managing water resources in the area. Its completion in 2018 marked a milestone in enhancing water storage capacity and mitigating flood risks. With its strategic location and design features, including a spillway and outlet gates, the dam contributes to the overall water management efforts in Texas. For those interested in water resource management and climate resilience, G3gc Ranch Dam serves as a noteworthy case study in sustainable infrastructure development and risk assessment in the face of changing environmental conditions.

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.
