Summary
Designed by W E SIMPSON, this buttress dam stands at 14 feet high and spans 201 feet in length, with a storage capacity of 160 acre-feet. Despite its relatively small size, Hoag Dam is regulated by the Texas Commission on Environmental Quality (TCEQ) and undergoes regular inspections to ensure its safety and compliance with state regulations.
With a primary purpose of recreation, Hoag Dam provides a serene and picturesque setting for water resource and climate enthusiasts to enjoy various outdoor activities. Its hazard potential is deemed not available, but its risk assessment is rated as high, indicating the importance of ongoing monitoring and maintenance to mitigate any potential risks. The dam lacks a spillway and locks, but features one outlet gate for controlled water release.
As a key infrastructure managed by local government authorities, Hoag Dam stands as a testament to the importance of sustainable water resource management and the need to balance recreational benefits with safety considerations in the face of changing climatic conditions. Its strategic location and design make it a valuable asset for the community, offering both leisure opportunities and water resource protection in a rapidly changing environment.

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.
