Summary

Hood Site 5, located in Coryell, Texas, is a privately owned earth dam designed by the USDA NRCS for debris control on Tr- Cottonwood Creek. Completed in 1993, this dam stands at a height of 18 feet and has a capacity of storing up to 181 acre-feet of water. With a low hazard potential and a moderate risk assessment rating of 3, Ft. Hood Site 5 plays a crucial role in managing water resources in the area.

Managed and funded by the Natural Resources Conservation Service, Ft. Hood Site 5 serves as a vital structure for controlling debris and ensuring the safety of nearby communities in the event of heavy rainfall or flooding. The dam's spillway, which is uncontrolled, has a width of 30 feet, allowing for the safe release of excess water and preventing potential damage to the surrounding area. Despite its low hazard potential, Ft. Hood Site 5 is regularly monitored and inspected to maintain its structural integrity and effectiveness in managing water flow.

With its strategic location and design, Ft. Hood Site 5 is an essential component of the water management infrastructure in the region. By providing critical debris control and storage capacity, this earth dam contributes to the overall resilience of the area against potential water-related hazards. As climate change continues to impact water resources, structures like Ft. Hood Site 5 play a crucial role in mitigating risks and ensuring the safety and well-being of local communities.

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.
