Summary
2, located in Worth, Missouri, is a privately owned earth dam completed in 1994 with a primary purpose of grade stabilization along the Middle Fork Grand River. With a height of 28 feet and a length of 330 feet, the dam has a storage capacity of 38 acre-feet and serves a drainage area of 25.6 square miles. Despite being unregulated by the state, the dam has a low hazard potential and is considered to have a moderate risk level.
The dam features an uncontrolled spillway with a width of 14 feet and has not been rated for its condition assessment. It is equipped with outlet gates and has a surface area of 2 acres. The risk management measures for Richards Dam No. 2 are currently not specified, and there is no Emergency Action Plan (EAP) in place. The dam is situated in an area represented by Congressman Sam Graves and falls under the jurisdiction of the Rock Island District of the US Army Corps of Engineers.
For water resource and climate enthusiasts, Richards Dam No. 2 presents an interesting case study in private dam ownership and management. With its role in grade stabilization and its location along the Middle Fork Grand River, the dam serves as a vital infrastructure in the region. The moderate risk level and lack of state regulation highlight the importance of monitoring and maintaining such structures to ensure public safety and environmental protection. Further research and assessment may be needed to develop appropriate risk management measures and emergency response plans for Richards Dam No. 2.

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.
