Summary
The dam, situated on El Sauz Creek, serves primarily for purposes other than flood control or water storage, with a storage capacity of 547 acre-feet. Despite its relatively small size, Perez Dam plays a crucial role in managing water resources in the area, with a drainage area of 143 square miles.
Managed by the Texas Commission on Environmental Quality (TCEQ), Perez Dam is subject to state regulations, inspections, and enforcement to ensure its structural integrity and safety. The risk assessment for the dam indicates a high risk level, with hazard potential and condition assessment currently not available or rated. While the dam lacks a spillway, it is equipped with one outlet gate for water release. The surrounding area benefits from the dam's services, with a surface area of 18 acres and a normal storage capacity of 58 acre-feet.
In the event of emergencies, the preparedness of Perez Dam is not fully detailed, with information on emergency action plans and inundation maps yet to be provided. Despite this, the dam continues to be a vital component of water resource management in the region, under the oversight of state agencies and with a focus on maintaining its functionality and safety for the community it serves.

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.
