Voigt Lake Dam Reservoir Report
Nearby: Boot Ranch Dam 1441 Longhorn Lake Dam
Last Updated: March 11, 2026
Voigt Lake Dam, located in Gillespie, Texas, was completed in 1971 by the USDA NRCS, with a primary purpose of water supply.
Summary
This private earth dam stands at a height of 31 feet and has a length of 745 feet, holding a maximum storage capacity of 98 acre-feet. Situated on Mayer Creek, Voigt Lake Dam plays a crucial role in water management in the region, ensuring a stable water supply for various purposes.
Despite being privately owned, Voigt Lake Dam is subject to state permitting and inspection requirements to ensure its structural integrity and safety. The dam has no spillway and is classified with a high risk assessment rating of 2, although its hazard potential and condition assessment are currently marked as "Not Available" and "Not Rated," respectively. While the dam has not been modified in recent years, ongoing risk management measures are essential to mitigate any potential hazards associated with its operation.
With its significant role in water supply and management, Voigt Lake Dam serves as a vital infrastructure in the region. The dam's association with the Natural Resources Conservation Service highlights the importance of sustainable water resource management practices. As climate change continues to affect water resources globally, the maintenance and upkeep of structures like Voigt Lake Dam are crucial in ensuring a resilient and reliable water supply for the community.

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.
