Summary
Constructed in 1956, this earth dam stands at a height of 20 feet and stretches 526 feet in length, with a storage capacity of 480 acre-feet. The dam's primary purpose is flood risk reduction, but it also caters to recreational activities in the area.
Managed by local government authorities and regulated by the Texas Commission on Environmental Quality (TCEQ), Ingram Lake Dam underwent structural modifications in 2011 to ensure its continued safety and functionality. The dam's condition assessment in April 2017 deemed it satisfactory, with regular inspections scheduled every five years. With a spillway width of 631 feet and a maximum discharge capacity of 38,320 cubic feet per second, the dam is equipped to handle significant water flows during times of high water levels.
Water resource and climate enthusiasts can appreciate Ingram Lake Dam's role in managing flood risks along the Guadalupe River while providing recreational opportunities for the local community. As a significant infrastructure asset in Kerr, Texas, this earth dam stands as a testament to the ongoing efforts to balance water resource management and environmental conservation in the region.

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.
