Summary

This private earth dam stands at a height of 26 feet and has a storage capacity of 364 acre-feet. The dam's primary function is to provide water resources for various needs in the area, with a normal storage capacity of 303 acre-feet and a surface area of 35 acres.

Managed by the Rock Island District of the US Army Corps of Engineers, Somerset South Dam has a low hazard potential and is currently rated as 'Not Rated' in terms of condition assessment. Despite not being regulated by the state, the dam plays a crucial role in water resource management for the region. The dam's location near the West Fork Medicine Creek tributary ensures a reliable source of water for fire protection and agricultural activities in the area.

With its strategic placement and capacity to store water, Somerset South Dam contributes significantly to the local ecosystem and community resilience. Water resource and climate enthusiasts can appreciate the dam's role in providing essential water supplies for various needs while also supporting wildlife habitats and enhancing overall water management practices in the region.

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.
