Summary
Constructed in 1943 by the Natural Resources Conservation Service, this earth dam stands at a height of 14 feet and has a storage capacity of 123 acre-feet. The dam's primary purposes and specific design details are not specified, but it is regulated by the South Dakota Department of Environment and Natural Resources (DENR), with state jurisdiction, permitting, inspection, and enforcement in place.
Despite its age, Blazek Dam has not been rated for its condition, and no recent inspection or emergency action plan updates are documented. The dam's maximum discharge capacity is 2,200 cubic feet per second, serving as a crucial water resource and climate management infrastructure in the region. With a length of 800 feet, Blazek Dam contributes to flood control and water storage, supporting agricultural activities and local ecosystems. While further assessments and risk management measures may be required, the dam remains a key component of the St. Paul District's water infrastructure network under private ownership.

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.
