Summary
Moriah, Missouri, is a vital structure designed by the USDA NRCS for flood risk reduction along the Panther Creek. Built in 1964, this earth dam stands at a height of 23 feet with a structural height of 29 feet and a length of 480 feet. It has a maximum storage capacity of 63.1 acre-feet and serves a drainage area of 1100 acres, with a normal storage capacity of 19.1 acre-feet. The dam is primarily owned and operated by the local government, with no state jurisdiction or permitting requirements.
Despite its low hazard potential, Panther Creek Watershed Dam B-11 is considered a moderate risk structure due to its age and condition assessment being currently not rated. The dam features uncontrolled spillways and other controlled outlet gates, ensuring effective water management during heavy rainfall events. While it has not undergone recent inspections or evaluations, the dam's risk management measures are not specified in the available data. With its strategic location and purposeful design, Panther Creek Watershed Dam B-11 continues to play a crucial role in safeguarding the surrounding area from potential flood risks, showcasing the importance of efficient water resource management in climate-sensitive regions like Missouri.

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.
