Summary

The dam is classified as an Earth dam with a height of 29 feet and a length of 315 feet, holding a maximum storage capacity of 116 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-Sabana River, the Whiteside Estate Lake Dam plays a crucial role in managing water resources in the area, particularly for agricultural and residential purposes. While the dam lacks a spillway, it is equipped with one outlet gate for controlled water release. The risk assessment for the dam is rated as high (2), highlighting the importance of proper maintenance and risk management measures to prevent potential hazards and ensure the safety of nearby communities.

With its strategic location and significant contribution to water supply management, Whiteside Estate Lake Dam stands as a key infrastructure asset in Eastland, Texas. As climate change continues to impact water resources, the dam's role in safeguarding water availability and quality remains essential. Ongoing monitoring and maintenance efforts are crucial to mitigate risks and uphold the dam's functionality for the benefit of the local population and ecosystem.

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.
