Summary
1, located in Denver, Missouri, is a privately owned earth dam built in 1994 for grade stabilization along the TR-East Fork Grand River. With a height of 28 feet and a length of 330 feet, the dam provides a storage capacity of 33 acre-feet and serves to control the flow of water in the area. The dam's spillway, with a width of 18 feet, is uncontrolled, and the hazard potential is rated as low.
Despite being privately owned, Wolfenbarger Dam No. 1 plays a crucial role in managing water resources in Worth County, Missouri. The dam's primary purpose is grade stabilization, and it has a moderate risk assessment rating. While not currently regulated or inspected by the state, the dam's structural integrity is not rated, and it lacks emergency action plans or updated contact information. Despite these gaps, the dam continues to effectively serve its purpose and contribute to the management of the local watershed.
Enthusiasts of water resources and climate in the area can appreciate Wolfenbarger Dam No. 1 for its role in controlling the flow of the TR-East Fork Grand River and stabilizing the surrounding grades. As a privately owned structure with a low hazard potential, the dam provides valuable storage capacity and contributes to the overall management of water resources in Worth County. While improvements in regulation, inspection, and emergency preparedness may be beneficial, the dam remains a vital component of the local watershed and an important asset for the community.

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.
