Summary
Built in 1938, this Earth-type dam stands at a height of 12 feet and has a length of 460 feet. With a storage capacity of 132 acre-feet, Marple serves as a crucial water resource for the region, particularly during times of low precipitation. Despite its age, the dam has a low hazard potential and is currently rated as "Not Rated" in terms of its condition assessment.
Managed by the South Dakota Department of Environment and Natural Resources (DENR), Marple is subject to state regulation and inspection to ensure its continued safety and functionality. The dam has not been modified in recent years and does not have an Emergency Action Plan in place. While it meets guidelines for risk assessment, there are no specific risk management measures outlined for this structure. With Dusty Johnson (R) representing the area in Congress, stakeholders and enthusiasts in water resource and climate fields can stay informed about the management and maintenance of Marple to ensure its long-term sustainability and effectiveness in water management for the region.

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.
