Summary
2 is a privately owned earth dam located in Mellette, South Dakota, along the tributary of Roundup Creek. Built in 1961, this dam stands at a height of 25 feet with a hydraulic height of 26 feet and a length of 180 feet. The dam has a storage capacity of 17 acre-feet and a maximum discharge of 250 cubic feet per second.
Despite being categorized as a low hazard potential structure, Novey No. 2 is regulated by the South Dakota Department of Environment and Natural Resources (DENR) and undergoes regular inspections, permitting, and enforcement to ensure its safety and compliance with state regulations. Although the dam's condition assessment is listed as "Not Rated," it meets the necessary guidelines for emergency action planning and risk management.
In the realm of water resource and climate enthusiasts, Novey No. 2 serves as a noteworthy example of a privately owned dam that plays a crucial role in water management and conservation efforts in South Dakota. With a focus on sustainability and safety, this dam stands as a testament to the importance of proper regulation and maintenance in ensuring the resilience of our water infrastructure in the face of changing climate conditions.

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.
