Summary
Constructed in 2000 by the USDA NRCS, this earth dam stands at a height of 34.2 feet and has a structural height of 42 feet, with a maximum storage capacity of 205 acre-feet. With a drainage area of 38.4 square miles and a maximum discharge of 3223 cubic feet per second, this structure plays a crucial role in managing water flow in the TR-HICKORY river system.
Despite its importance in flood control, the dam is rated as having a high hazard potential, underscoring the need for regular inspections and maintenance. The last inspection was conducted in September 2002, with a scheduled frequency of every 3 years. While the condition assessment is currently marked as "Not Rated," the risk assessment categorizes the structure as having a moderate risk level. The dam features an uncontrolled spillway and outlet gates, highlighting the reliance on natural flow patterns to manage excess water.
This watershed structure serves as a vital resource for the local government in Neosho, Missouri, demonstrating the collaborative efforts between agencies like the USDA NRCS in ensuring the safety and resilience of communities in the face of climate challenges. As climate change continues to impact water resources, structures like H- 11 will play a critical role in mitigating flood risks and safeguarding the environment for future generations.

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.
