Summary

Built in 1986, this private earth dam structure spans 405 feet in length and reaches a height of 33 feet, with a maximum storage capacity of 163 acre-feet. This picturesque pond serves as a popular spot for outdoor enthusiasts, offering a surface area of 4 acres and a drainage area of 120 acres along the Gasconade River.

Despite its low hazard potential and moderate risk assessment, Norbert Sandbothe Pond has not been rated for its condition assessment. With a spillway type designated as "Uncontrolled" and an absence of outlet gates, this recreational reservoir relies on natural drainage mechanisms. Furthermore, the pond's location in a rural setting underscores the need for ongoing monitoring and risk management measures to ensure the safety of visitors and the surrounding ecosystem. As climate change continues to impact water resources, the sustainability of Norbert Sandbothe Pond as a recreational destination will be contingent upon adaptive management practices and proactive stewardship efforts.

Overall, Norbert Sandbothe Pond serves as a valuable resource for the local community in Vienna, Missouri, offering a tranquil setting for outdoor recreation and leisure activities. As water resource and climate enthusiasts, it is essential to recognize the importance of responsible management practices in safeguarding such vital water bodies. By staying informed and engaged in the upkeep and preservation of places like Norbert Sandbothe Pond, we can contribute to the long-term sustainability and enjoyment of our natural environment for generations to come.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
