Garwood Lake Dam Reservoir Report
Last Updated: March 4, 2026
Garwood Lake Dam, located in Uvalde, Texas, was completed in 1971 with the primary purpose of water supply.
Summary
This private-owned earth dam stands at a height of 17 feet and stretches 275 feet in length, creating a reservoir with a storage capacity of 200 acre-feet. The dam is situated on the TR-Frio River and is regulated by the state with regular inspections to ensure its structural integrity.
Despite being classified as having a high risk potential, the condition of Garwood Lake Dam is currently not rated. It does not have a spillway and features one outlet gate for water control. The dam plays a crucial role in providing water supply to the surrounding area, with a normal storage capacity of 112 acre-feet. While it may not have a designated emergency action plan in place, the dam remains an important infrastructure for water resource management in the region.
In the realm of water resource and climate enthusiasts, Garwood Lake Dam represents a pivotal structure in the conservation and utilization of water in Uvalde, Texas. Its strategic location on the TR-Frio River, combined with its storage capacity and operational history, underscores its significance in sustaining water supply for the local community. With ongoing monitoring and maintenance, the dam continues to fulfill its essential role in water management while embodying the nexus between human development and environmental stewardship.

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.
