Summary
Built in 1978 by the USDA NRCS, this dam stands at a height of 28 feet with a length of 674 feet, providing a storage capacity of 49 acre-feet. Although it is primarily used for purposes other than flood control or water supply, the dam is regulated by the state with permitting and inspection requirements in place.
Despite its relatively small size and limited surface area, Evans Gss has a high hazard potential, with a risk assessment rating of 2 out of 3. The condition of the dam is currently not rated, and there is no emergency action plan (EAP) in place. With no spillway and only one outlet gate, the dam's risk management measures and inundation maps are currently not prepared or up to date.
For water resource and climate enthusiasts, Evans Gss presents an interesting case study of a privately owned earth dam in Texas with a significant hazard potential. As efforts to address aging infrastructure and improve dam safety continue, monitoring and assessing the condition of dams like Evans Gss will be crucial to ensuring the safety and resilience of water resources in the area.

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.
