Summary
Built in 1914, this earth dam stands at a height of 11 feet and stretches 850 feet in length, with a storage capacity of 265 acre-feet. The dam serves the primary purpose of recreation, offering a surface area of 37.4 acres for outdoor activities and water-based leisure.
Despite its historical significance and recreational value, Pilgrim Lake Dam has faced challenges in terms of maintenance and safety. A recent inspection in April 2021 rated the dam's condition as "unsatisfactory," highlighting the need for structural improvements and risk management measures. The dam is regulated by the Texas Commission on Environmental Quality (TCEQ) and undergoes regular inspections to ensure compliance with state regulations and safety standards.
With a moderate risk assessment rating, Pilgrim Lake Dam remains a focal point for water resource and climate enthusiasts, serving as a reminder of the delicate balance between water management, recreational opportunities, and environmental stewardship. As discussions around dam safety and maintenance continue, stakeholders are working towards ensuring the long-term sustainability and safety of this vital infrastructure in Atascosa County, Texas.

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.
