Summary

Built in 1989 by the USDA NRCS, this earth dam stands at a height of 18 feet and has a structural height of 20 feet, with a length of 770 feet. The dam has a storage capacity of 128 acre-feet, with a normal storage level of 29 acre-feet, serving a drainage area of 150 square miles.

Despite being categorized as having a low hazard potential, this dam plays a crucial role in mitigating flood risks in the area. With a moderate risk assessment rating, it is important for the local government to ensure that proper risk management measures are in place to safeguard the surrounding communities. While the dam is currently in 'Not Rated' condition, regular inspections and maintenance are essential to ensure its continued effectiveness in flood control and protection of downstream areas.

Managed by the Natural Resources Conservation Service, Troublesome Creek Watershed Dam T- 29 serves as a testament to the collaborative efforts between federal agencies and local governments in safeguarding communities against the impacts of extreme weather events. As a key component in the flood risk reduction infrastructure, this dam underscores the importance of proactive planning and maintenance to ensure the resilience of water resources in the face of a changing climate.

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.
