Summary
Hoffman No. 2 is a private-owned dam located in Meade, South Dakota, along a Moreau tributary. Built in 1962 by the Natural Resources Conservation Service, this earth dam stands at a height of 24 feet and has a storage capacity of 86 acre-feet. With a low hazard potential and a "Not Rated" condition assessment, this structure plays a crucial role in managing water resources in the area.
Despite its age, E. Hoffman No. 2 is regulated by the state and undergoes regular inspections, permitting, and enforcement by the South Dakota Department of Environment and Natural Resources (DENR). With a maximum discharge capacity of 2000 cubic feet per second, this dam serves as a key infrastructure for flood control and water supply in the region. Its location within the St. Paul District of the US Army Corps of Engineers ensures that it meets stringent safety standards.
Water resource and climate enthusiasts will appreciate the importance of E. Hoffman No. 2 in safeguarding the surrounding area from potential flooding events. As a vital piece of infrastructure with a long history of service, this dam continues to play a crucial role in water management efforts in Meade, South Dakota. Its low hazard potential and state-regulated status underscore the significance of maintaining and monitoring this structure for the benefit of the local community and the environment.

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.
