Summary
The primary purpose of this earth dam structure is irrigation, with a maximum storage capacity of 800 acre-feet. The reservoir covers a surface area of 72 acres and has a structural height of 12 feet.
Managed by the Texas Commission on Environmental Quality (TCEQ), the Engelman Gardens Reservoir Levee is regulated by the state and undergoes regular inspections and enforcement to ensure its safety and functionality. Despite being rated as having a high risk potential, the condition of the dam is currently not assessed. The dam features a valve outlet gate and does not have a spillway, with a stone core and soil foundation supporting its structure.
For water resource and climate enthusiasts, the Engelman Gardens Reservoir Levee presents an intriguing case study of a local government-owned dam designed for irrigation purposes. With its location along the Rio Grande and the involvement of state regulatory agencies, this earth dam structure serves as a vital component of the region's water management system. Ongoing risk assessments and management measures are essential to safeguard the reservoir and ensure its continued operation for irrigation needs in the area.

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.
