Summary
Completed in 1950, this earth dam stands at a height of 8 feet and spans 5300 feet in length, with a storage capacity of 240 acre-feet. The reservoir serves as a vital resource for water management in the region, particularly for agricultural irrigation along the Rio Grande.
Managed by the Texas Commission on Environmental Quality (TCEQ), the Hargill Reservoir Levee is regulated, inspected, and enforced by state authorities to ensure its structural integrity and safety. While the dam is currently rated as not available in terms of hazard potential and condition assessment, its risk assessment is classified as high. With no spillway and limited outlet gates, the reservoir presents unique challenges in emergency response and risk management.
Water resource and climate enthusiasts will appreciate the significant role that the Hargill Reservoir Levee plays in sustaining agricultural activities in the area. As a privately owned structure with state oversight, the dam highlights the importance of proactive maintenance and monitoring to mitigate potential risks and ensure the continued reliability of this essential water infrastructure.

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.
