Summary

Completed in 1966, the dam serves multiple purposes including irrigation, recreation, and water supply, with a primary focus on irrigation. Standing at 91 feet in height and stretching 17,539 feet in length, the dam has a storage capacity of 1,460,000 acre-feet and covers a surface area of 25,850 acres.

Situated on Cedar Creek, Joe B Hogsett Dam is regulated by the Texas Commission on Environmental Quality (TCEQ) and undergoes regular inspections to ensure its structural integrity and functionality. The dam features a controlled spillway with a width of 45 feet and is equipped with five outlet gates for water management. With a high-risk assessment due to its critical role in water resource management, the dam plays a crucial part in the region's agricultural and recreational activities.

With a maximum discharge of 316,821 cubic feet per second, Joe B Hogsett Dam plays a vital role in flood control and water management in the area. Its strategic location in Trinidad, Texas, along with its impressive storage capacity and multiple usage purposes, make it a key infrastructure element for water resource and climate enthusiasts to study and appreciate in the region.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
