Summary
Built in 1965 by the USDA NRCS, this earth dam stands at a height of 28 feet and spans 950 feet in length, providing a storage capacity of 368 acre-feet. It is designed to mitigate flood risks along the TR-Yocona River and Kettle Creek, showcasing the collaborative efforts of local government and state regulatory agencies in ensuring water resource management.
Despite its critical role in flood control, the dam has been rated with a high hazard potential and an unsatisfactory condition assessment during its last inspection in January 2018. The structure operates with uncontrolled spillways and outlet gates, highlighting the importance of regular monitoring and maintenance to uphold its integrity and functionality. The dam's associated risk assessment indicates moderate risk, emphasizing the need for ongoing risk management measures and emergency preparedness protocols to safeguard the surrounding communities and environment from potential hazards.
As water resource and climate enthusiasts, understanding the intricacies of the Upper Yocona Watershed Structure Y-14-01 Dam sheds light on the intersection of infrastructure, environmental stewardship, and public safety. By delving into the specifics of its design, purpose, and regulatory oversight, we gain insight into the challenges and responsibilities associated with managing essential water resources in a changing climate. The dam serves as a crucial piece of the puzzle in ensuring sustainable water management practices and resilience against natural disasters, highlighting the ongoing efforts required to protect our communities and ecosystems for future generations.

Condition Assessment
SatisfactoryNo 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
HighDams 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.
