Summary

Managed by the US Army, this dam stands at a height of 21 feet and spans 560 feet in length, with a storage capacity of 135 acre-feet. Despite its low hazard potential, the dam has a moderate risk assessment rating of 3, indicating a potential need for risk management measures in the future.

Situated on the Coryell River within the Bell County, Dam 36 plays a crucial role in flood control and water resource management in the region. With a normal storage capacity of 64 acre-feet and a maximum discharge rate of 18,795 cubic feet per second, the dam serves as a vital infrastructure for water supply and environmental protection in the area. The dam's uncontrolled spillway type and its location in the Fort Worth District highlight its significance in the overall water infrastructure network.

Although the dam's condition assessment is not available at this time, its last inspection in September 2020 deemed it to have a low hazard potential. With a designated inspection frequency of 4, Dam 36 remains a key structure for the US Army in terms of operations, construction, and regulation. As climate change continues to impact water resources, Dam 36's role in managing water flow and storage is essential for ensuring the safety and sustainability of the surrounding communities and ecosystems.

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.
