Summary
With a height of 15 feet and a length of 1650 feet, this dam has a storage capacity of 660 acre-feet and serves as a vital resource for the surrounding area. Despite not having a spillway, the dam is designed to withstand high risk situations, as it is state regulated and inspected by the TCEQ.
The dam's location on TR-LOS OLMUS CREEK makes it a crucial asset for water resource management and climate resilience in the region. As a part of the Galveston District, Glass Dam plays a key role in providing water for agricultural and recreational activities. While the dam's hazard potential is not available, its high risk assessment underscores the importance of proper maintenance and emergency preparedness to protect the community and environment from potential dangers.
As water resource and climate enthusiasts, understanding the significance of Glass Dam in ensuring water security and mitigating risks is essential. With its strategic design and purposeful construction, this dam stands as a symbol of resilience and sustainability in the face of changing environmental conditions. By recognizing the value of infrastructure like Glass Dam, we can work towards a more resilient and water-secure future for generations to come.

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.
