Summary
2 is a privately owned earth dam located in Tripp, South Dakota, along the TR. OLD LODGE CREEK. Managed by KONECHNE ENG., this structure stands at 24 feet in height with a storage capacity of 260 acre-feet. While its hazard potential is rated as low, the risk assessment indicates a moderate risk level (3), highlighting the need for ongoing monitoring and management.
This dam, regulated by the South Dakota Department of Environment and Natural Resources (DENR), is designed for flood control and water resource management. With a spillway width of 120 feet and a maximum discharge capacity of 1620 cubic feet per second, Snavely No. 2 plays a crucial role in safeguarding the surrounding area from potential flooding events. Despite being in a moderate risk category, the dam's condition is currently not rated, emphasizing the importance of regular inspections and maintenance.
As a vital component of the local water infrastructure, Snavely No. 2 serves as a key asset in mitigating flood risks and ensuring sustainable water management in the region. With its strategic location and design features, this dam plays a pivotal role in protecting the community and the environment. Continued regulatory oversight and adherence to safety protocols will be essential in maintaining the integrity and functionality of this critical water resource structure.

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.
