Summary
Completed in 1959, this private dam serves primarily for recreation purposes, offering a serene environment for visitors to enjoy the surrounding natural beauty. With a height of 24.4 feet and a length of 1760 feet, Moro Lake Dam holds a normal storage capacity of 1093 acre-feet and a maximum storage of 1873 acre-feet, ensuring a reliable water supply for the area.
Managed by the Texas Commission on Environmental Quality (TCEQ), Moro Lake Dam is subject to state regulations, inspections, and enforcement to maintain its structural integrity and safety. The dam's spillway, with a width of 195 feet, is designed as uncontrolled, allowing for controlled water release during periods of high inflow. The risk assessment for Moro Lake Dam indicates a moderate level of risk (3), highlighting the importance of ongoing monitoring and maintenance to mitigate potential hazards and ensure the safety of the surrounding community.
As a key feature in the TR-El Moro Creek watershed, Moro Lake Dam plays a crucial role in managing water resources and supporting ecological diversity in the region. With its picturesque setting and essential function in water management, this dam serves as a focal point for water resource and climate enthusiasts seeking to understand the intersection of human infrastructure and natural ecosystems in sustaining a healthy environment.

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.
