Summary
Its hazard potential is rated as "Low" and its condition assessment is listed as "Not Rated."
Managed by the St. Paul District of the US Army Corps of Engineers, Sherburne National Pool 7b plays a crucial role in regulating the flow of the St. Francis River-TR. Despite its low hazard potential, the dam has not been inspected recently, with the last recorded inspection frequency being 8 years. The emergency action plan (EAP) status, risk assessment, and risk management measures for the dam are currently listed as unknown, indicating a potential need for further evaluation and preparedness.
For water resource and climate enthusiasts, Sherburne National Pool 7b serves as a significant infrastructure in Sherburne County, Minnesota, contributing to water storage and flow regulation in the region. The dam's location and design are essential factors in managing water resources and ensuring the safety and security of the surrounding area. With its low hazard potential and unknown condition assessment, there is a potential opportunity for stakeholders to prioritize inspection, risk assessment, and emergency preparedness efforts for this vital water management structure.

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.
