Summary
Francis River. With a low hazard potential and a satisfactory condition assessment, Sherburne National Dike 6a serves as a critical infrastructure piece in the region.
This dam has a normal storage capacity of 956 acre-feet and a maximum storage of 1673 acre-feet, making it a significant component in the water resource management system of Sherburne County. While the dam has not been modified in recent years, it underwent its last inspection in 2007, with a regular inspection frequency of 8 years. With Tom Emmer (R) as the representative for this district, Sherburne National Dike 6a plays a crucial role in protecting the surrounding areas from potential flooding events and ensuring the efficient management of water resources in the region.
Despite its simple design as an earth dam with buttress core types, Sherburne National Dike 6a remains a vital structure for maintaining water levels and protecting against flood risks in the Sherburne County area. With its satisfactory condition assessment and low hazard potential, this dam stands as a testament to effective water resource management and climate resilience efforts in Minnesota.

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.
