Summary
This earth dam, primarily used for recreation, has a storage capacity of 346 acre-feet and covers a surface area of 22 acres. Despite its recreational purpose, the dam poses a high risk, with a hazard potential of "Not Available" and a risk assessment rating of 2.
Owned privately, Frossard Lake Dam is not regulated by the state but undergoes regular inspections and permitting processes. With no spillway and a single outlet gate, the dam's structural integrity is crucial for ensuring safety in the area. Although the dam's condition has not been officially rated, its risk level and lack of emergency action planning highlight the need for continued monitoring and maintenance to prevent potential hazards.
Situated on TR-Clear Creek and managed by the Galveston District, Frossard Lake Dam serves as a vital recreational resource in the region. However, its high risk classification underscores the importance of proactive risk management measures to mitigate potential threats and ensure the safety of the surrounding community and environment.

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.
