Summary
Built in 1968 by the USDA NRCS, this private earth dam stands at 8 feet tall with a length of 920 feet, providing a storage capacity of 128 acre-feet. The dam is situated on the TR-SAN JOSE CREEK and is crucial for supporting the local ecosystem and agricultural activities in the area.
Despite being a private structure, Walker Lake Dam is subject to state permitting and inspection requirements to ensure its safety and functionality. With a high risk assessment rating of 2, there is a need for proactive risk management measures to mitigate potential hazards. Although the dam has not been rated for its condition, it remains an essential asset for water resource management in the region. Further assessment and emergency preparedness protocols may be necessary to enhance the dam's resilience.
As water resource and climate enthusiasts, understanding the significance of Walker Lake Dam in maintaining water supply and supporting local activities is crucial. With its strategic location and multiple functions, the dam plays a vital role in sustaining the surrounding environment. Continued monitoring, maintenance, and risk management efforts are essential to ensure the long-term viability and safety of this important water infrastructure in Texas.

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.
