Summary
This private-owned Earth dam stands at a height of 24 feet and has a length of 2250 feet, providing a maximum storage capacity of 806 acre-feet. The dam is situated on the TR-ARROYO BOLENO river/stream, under the regulatory oversight of the Texas Commission on Environmental Quality (TCEQ).
With a primary purpose of water supply, Vidaurri Lake Dam plays a crucial role in managing water resources in the area. Despite being rated with a high risk level, the dam's condition assessment is currently not rated. The dam does not have a spillway and is equipped with one outlet gate. As a private-owned structure, the dam is subject to state regulation, inspection, and enforcement to ensure its safety and compliance with relevant guidelines.
For water resource and climate enthusiasts, Vidaurri Lake Dam presents an intriguing case study in water management and infrastructure development. Its location in a high-risk area underscores the importance of effective risk assessment and management measures for ensuring the safety and reliability of such critical structures. As efforts continue to monitor and maintain the dam, it serves as a reminder of the intricate interplay between water resources, infrastructure, and environmental stewardship 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.
