Summary
The dam stands at a height of 14 feet and has a primary purpose of water supply, with a storage capacity of 100 acre-feet. It is a buttress-type dam designed by NATIONAL ENGINEERING CO and is regulated by the Texas Commission on Environmental Quality (TCEQ).
Despite being rated as "Not Available" in terms of hazard potential and "Not Rated" in condition assessment, Wayne Smith Dam is considered to have a high risk level (2). The dam does not have a spillway and is equipped with one outlet gate. The last inspection date recorded was in April 1979, and the dam has not undergone any modifications or condition assessments since then.
Enthusiasts of water resources and climate in the area can appreciate Wayne Smith Dam for its crucial role in providing water supply to the community. The dam's location along the Blanco River adds to its significance in managing water resources in the region. As the dam continues to be monitored by the TCEQ and other regulatory agencies, it serves as a key infrastructure for water management and conservation efforts in Blanco, Texas.

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.
