Summary

Managed by the US Army, this dam serves primarily for recreational purposes, including providing a fish and wildlife pond, water supply, and recreational activities. Standing at a height of 26 feet and a length of 445 feet, Dam 33 has a storage capacity of 348 acre-feet, with a normal storage level of 80 acre-feet.

With a moderate risk level and a low hazard potential, Dam 33 is classified as having an uncontrolled spillway type with a width of 50 feet. Despite not being regulated by the state, the US Army oversees the construction, inspections, and operations of this dam. The last inspection took place in September 2020, with a frequency of every four years. While the condition assessment is not available, the Emergency Action Plan (EAP) was last revised in May 2010, ensuring that the necessary risk management measures are in place.

Water resource and climate enthusiasts will find Dam 33 to be an intriguing structure due to its Federal ownership, unique design features, and recreational purposes. With its location in Belton, Texas, and proximity to the Fort Worth District, this dam offers a glimpse into the management and operation of water infrastructure by the US Army. Despite its low hazard potential, the moderate risk level and periodic inspections ensure the safety and functionality of Dam 33 for the surrounding community and wildlife.

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.
