Summary
Schrempp, a privately owned earth dam located in Dewey, South Dakota, was completed in 1961 and stands at a height of 30 feet with a length of 350 feet. Built on the TR-MOREAU river, this dam has a maximum storage capacity of 96 acre-feet and a normal storage capacity of 42 acre-feet. With a low hazard potential and a condition assessment of "Not Rated," R. Schrempp is regulated by the South Dakota Department of Environment and Natural Resources (DENR) and is subject to state permitting, inspection, and enforcement.
Despite not being rated for its condition, R. Schrempp has demonstrated its reliability as a water resource infrastructure over the years. Situated in the St. Paul District of the US Army Corps of Engineers, this dam plays a crucial role in flood control and water management in the region. With a maximum discharge capacity of 245 cubic feet per second, R. Schrempp serves as a vital structure in protecting the surrounding area from potential flooding events.
Although not currently assessed for its emergency action plan or risk management measures, R. Schrempp remains a key piece of infrastructure in the region. With its strategic location and design, this dam continues to contribute to the overall water resource management efforts in South Dakota, under the watchful eye of regulatory authorities and state agencies.

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.
