Summary
Hoffman No. 1 is a privately owned earth dam located in Meade, South Dakota, along the TR-MOREAU river. Constructed in 1968, this dam stands at a height of 23 feet and has a storage capacity of 87 acre-feet, with a normal storage level of 38 acre-feet. The dam's primary purpose and associated structures are not specified, but it is regulated by the South Dakota Department of Environment and Natural Resources (DENR), with state permitting, inspection, and enforcement protocols in place.
Despite being rated as having a low hazard potential and not yet assessed for its condition, E. Hoffman No. 1 plays a crucial role in water resource management and flood control in the region. The dam's maximum discharge capacity is recorded at 2100 cubic feet per second, serving as a vital tool in mitigating the risk of flooding in the area. Managed by the Natural Resources Conservation Service, this dam contributes to the overall water conservation efforts in South Dakota.
With its strategic location and key role in water resource management, E. Hoffman No. 1 stands as a testament to the collaborative efforts between private owners and state regulatory agencies in safeguarding water resources and addressing climate-related challenges. As climate change continues to impact water availability and quality, dams like E. Hoffman No. 1 play a crucial role in ensuring sustainable water management practices for the benefit of both local communities 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.
