Lowrance Lake Dam Reservoir Report
Last Updated: December 10, 2025
Lowrance Lake Dam, located on Quemado Creek in Maverick County, Texas, was completed in 1940 and serves as a vital water supply source for the region with a storage capacity of 360 acre-feet.

Summary
The dam, primarily used for water supply purposes, is a privately owned earth dam with a height of 18 feet and a hydraulic height of 18 feet. While the dam does not have a spillway, it is equipped with one outlet gate for water release.
Despite being last inspected in 1990 and currently not rated for condition assessment, the dam poses a high risk (2) due to its unknown hazard potential and lack of available risk assessment information. Although the dam is not regulated by the state and has not been enforced for compliance, it does undergo regular state inspections and permitting processes. With its proximity to the Fort Worth District and the oversight of Representative Will Hurd (R), the Lowrance Lake Dam remains an essential structure for maintaining water resources in the area, especially during times of changing climate patterns and water scarcity concerns.

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.
