Summary
3 is a private-owned earth dam located in Mellette, South Dakota, along the tributary of Roundup Creek. Built in 1969 and standing at a height of 25 feet, this dam has a storage capacity of 16 acre-feet and a maximum discharge of 250 cubic feet per second. Despite its low hazard potential, the dam has not been rated for its condition assessment, and its emergency action plan status remains unknown.
Managed by the South Dakota Department of Environment and Natural Resources, Novey No. 3 is subject to state regulation, permitting, inspection, and enforcement. The dam's primary purpose and associated structures are unspecified, but it serves as a critical infrastructure for water resource management in the region. With its strategic location and design, Novey No. 3 plays a crucial role in mitigating flood risks and ensuring water availability for the local community.
As climate change continues to impact water resources and weather patterns, the maintenance and monitoring of dams like Novey No. 3 become increasingly important for climate resilience and adaptation. Understanding the condition and functionality of such structures is essential for effective risk management and emergency preparedness in the face of changing environmental conditions. With its historical significance and ongoing role in water management, Novey No. 3 represents a valuable asset in the region's efforts to address the challenges of a changing climate.

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.
