Summary
Strand, located in Perkins, South Dakota, is a privately owned earth dam completed in 1951 on the TR MOREAU RIVER. Standing at a height of 21 feet with a length of 430 feet, it has a storage capacity of 62 acre-feet and a maximum discharge of 200 cubic feet per second. The dam is regulated by the South Dakota Department of Environment and Natural Resources (DENR), ensuring that it meets state permitting, inspection, and enforcement standards.
Despite its low hazard potential, G.M. Strand's condition has not been rated, and there is no information available on its emergency action plan or risk assessment. The dam does not have any associated structures or outlet gates, indicating a straightforward design focused on water storage and flood control. With its location in the St. Paul District of the US Army Corps of Engineers, G.M. Strand serves as an essential water resource infrastructure for the region, contributing to water management efforts in the area.
For water resource and climate enthusiasts, G.M. Strand provides a fascinating case study of a mid-century earth dam in South Dakota. Its history, design, and regulatory oversight offer insights into the complex interplay of infrastructure, environmental stewardship, and public safety in managing water resources. As discussions around climate change and water scarcity intensify, understanding the role and management of dams like G.M. Strand becomes increasingly important for ensuring sustainable water management practices in the face 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.
