Summary
Standing at a height of 20 feet and with a storage capacity of 214 acre-feet, this structure on the TR North Fork river serves as a vital resource for the local community. Despite its low hazard potential, Mononame 796 has not been rated for its condition, and information on its inspection frequency and emergency preparedness is currently unavailable.
Managed by the Little Rock District of the US Army Corps of Engineers, Mononame 796 plays a crucial role in water resource management in the region. With the dam's normal storage capacity of 40 acre-feet and a drainage area of 165 acres, it contributes to the sustainable utilization of water for various purposes. While the dam's risk assessment and emergency action plan status are unknown, its position as a key water supply infrastructure underscores its importance for both the environment and the community.
As a significant feature on the TR North Fork river, Mononame 796 represents a valuable asset for water resource and climate enthusiasts. With its strategic location in the city of Marshfield, Missouri, this earth dam not only provides essential water supply services but also underscores the importance of infrastructure resilience in mitigating potential hazards. Despite lacking certain assessments and updated information, Mononame 796 stands as a testament to the critical role of dams in ensuring water security and environmental sustainability in the region.

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.
