Summary
Moriah, Missouri, serves as a critical flood risk reduction structure along the TR-Little Panther stream. Built in 1971 by the USDA NRCS, this earth dam stands at a height of 31 feet and spans 880 feet in length, with a storage capacity of 840 acre-feet and a drainage area of 510 square miles. Despite its low hazard potential, the dam plays a crucial role in protecting the local community from potential flooding events.
With a primary purpose of flood risk reduction, Panther Creek Watershed Dam D-1 is designed to withstand maximum discharge of 1260 cubic feet per second and features an uncontrolled spillway with a width of 80 feet. Although the dam is currently deemed to be in "Not Rated" condition, its risk assessment is moderate, indicating the need for ongoing monitoring and maintenance. As a key component of the water resource infrastructure in Harrison County, Missouri, this dam highlights the importance of effective management and operation to ensure public safety and environmental sustainability in the region.
As water resource and climate enthusiasts continue to advocate for resilient infrastructure, Panther Creek Watershed Dam D-1 stands as a testament to the collaborative efforts of local government agencies and the NRCS in mitigating flood risks and protecting communities. While the dam's current risk assessment suggests a moderate level of vulnerability, ongoing evaluation and risk management measures are essential to safeguarding the surrounding area from potential hazards. By recognizing the critical role of structures like Panther Creek Watershed Dam D-1, stakeholders can work together to address climate challenges and ensure the long-term viability of water resources in the region.

Dam Data Reference
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.
