Summary
This earth dam stands at a height of 29 feet and spans a length of 2050 feet, with a storage capacity of 1700 acre-feet. It serves a primary purpose of "Other" and is regulated by the Texas Commission on Environmental Quality (TCEQ).
The dam, situated on the TR-Evans Creek, does not have a spillway and is equipped with one outlet gate. Despite being categorized as "Not Rated" in terms of condition assessment, it has a high risk level of 2. The risk management measures and emergency action plans for this dam have not been updated or prepared, indicating potential vulnerabilities in case of emergencies.
For water resource and climate enthusiasts, the Gillis East Lake Dam presents a case study in the maintenance and regulation of private dams in Texas. The dam's design, height, and storage capacity offer insight into its role in water management and conservation efforts in the region. Understanding the risk assessment and management challenges associated with this dam can provide valuable lessons for sustainable water resource management in the face of changing climate 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.
