Summary
Built on Tordillo Creek, this dam has a storage capacity of 220 acre-feet, with a normal storage level of 176 acre-feet. Despite its lack of a spillway, the dam is equipped with one outlet gate for water release.
The dam's risk assessment has been classified as high, indicating potential hazards that require close monitoring and management. Although its condition has not been rated, the dam is considered to have a hazard potential that is not currently available. The dam's emergency action plan status and other safety measures have not been specified, suggesting a need for further evaluation and preparation to ensure the safety of the surrounding area and water resources.
For water resource and climate enthusiasts, Mega Pit Dam presents an intriguing case study of a privately owned structure in Texas that plays a vital role in water storage and management. With its high risk classification and lack of detailed safety assessments, this dam highlights the importance of effective monitoring and emergency preparedness in safeguarding communities and ecosystems from potential disasters related to dam failures and inundation.

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.
