Summary

The pond serves multiple purposes and has a storage capacity of 270 acre-feet. Despite its relatively small size with a surface area of 26 acres and a drainage area of 0.6 square miles, the dam plays a crucial role in managing water resources in the region, particularly for flood control and water supply.

The dam's low hazard potential and satisfactory condition assessment make it a reliable structure for water management. It has a spillway type of "Uncontrolled" and a maximum discharge capacity of 85 cubic feet per second. The dam is under state regulation and oversight by the Minnesota Department of Natural Resources, ensuring that it meets safety standards and environmental regulations. With its moderate risk assessment rating and regular inspection schedule, Dvorak F Pond demonstrates a commitment to effective risk management and safety protocols.

Overall, Dvorak F Pond is a significant water resource infrastructure in Scott County, Minnesota, contributing to water storage, flood control, and environmental protection in the region. Its history of successful operation and maintenance, along with its compliance with state regulations, highlight its importance in the local water management system. For water resource and climate enthusiasts, Dvorak F Pond serves as a fascinating example of how small-scale dams can play a vital role in managing water resources and mitigating risks in a changing climate.

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.
