Summary
Managed by the Natural Resources Conservation Service, this dam has a storage capacity of 54 acre-feet and a maximum discharge of 756 cubic feet per second. Despite its low hazard potential and a condition assessment of "Not Rated," Joe Schomer 2 is regulated by the South Dakota Department of Environment and Natural Resources, with state permitting, inspection, and enforcement in place to ensure its safe operation.
Situated on a tributary of the Missouri River, Joe Schomer 2 serves as a vital water resource for the surrounding area, with a normal storage capacity of 23 acre-feet. Although the dam has not been modified in recent years and lacks a detailed risk assessment, its presence contributes to flood control and water management efforts in the region. While specific purposes for the dam are not listed, its strategic location and design indicate a focus on protecting downstream communities and enhancing agricultural irrigation practices.
As an essential component of the local water infrastructure, Joe Schomer 2 plays a crucial role in maintaining water quality, regulating water flow, and supporting various water-related activities in the area. With its historical significance dating back to the 1960s, this earth dam stands as a testament to the importance of sustainable water resource management and the collaboration between private owners and regulatory agencies to ensure the safety and efficiency of water storage and distribution systems.

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.
