Summary

The dam, classified as an Earth type with a buttress core, stands at a height of 17 feet and has a storage capacity of 218 acre-feet. Despite being privately owned, the dam is regulated by the state and undergoes regular inspections to ensure its structural integrity.

Situated on the TR-OLMOS CREEK, Smith Dam 2 plays a crucial role in managing water resources in the area. With a surface area of 22 acres and a normal storage capacity of 123 acre-feet, the dam helps meet the water needs of the community. While the dam does not have a spillway, it is equipped with one outlet gate for controlled water release.

Although the dam's hazard potential is not currently available, it is categorized as having a high risk level. The condition of the dam is not rated, highlighting the importance of ongoing monitoring and maintenance to ensure its continued functionality. With its strategic location and role in water supply, Smith Dam 2 remains a key infrastructure for water resource management in Atascosa, Texas.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
