Summary
This earth dam, with a height of 18 feet and a length of 650 feet, provides a storage capacity of 216 acre-feet and a surface area of 19 acres. While the dam does not have a spillway, it is equipped with one outlet gate for water management. Despite its age, the dam's condition assessment is not rated, and it carries a high risk potential.
Owned privately and not regulated by the state, Cobb Lake Dam presents a unique challenge for water resource and climate enthusiasts. With no designated hazard potential or emergency action plan in place, the dam's risk management measures are not clearly defined. The absence of inundation maps and updated emergency contacts raises concerns about the dam's ability to handle potential emergencies effectively. Furthermore, the dam's high risk classification calls for a more thorough evaluation of its structural integrity and safety protocols to ensure the surrounding community's protection.
As a part of the Galveston District, the lack of state oversight and regulation at Cobb Lake Dam calls for increased vigilance from water resource and climate activists. With the dam's high risk potential and limited information available on its risk management measures, there is a pressing need for comprehensive inspections, hazard assessments, and emergency preparedness strategies. As enthusiasts advocate for transparency and accountability in water resource management, the spotlight turns to Cobb Lake Dam as a case study in balancing private ownership with public safety and environmental stewardship.

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.
