Summary
This rockfill dam stands at 21.2 feet in height and serves the primary purpose of flood risk reduction along Lazarus Creek. With a storage capacity of 61 acre-feet and a surface area of 3 acres, the dam plays a crucial role in mitigating potential flooding in the area.
Despite its low hazard potential, Norman Twp 7 has not been rated for its condition assessment as of the last inspection in May 2019. The dam has not undergone any modifications in recent years and lacks certain emergency preparedness measures such as an Emergency Action Plan (EAP) and inundation maps. However, with state permitting, inspection, and enforcement in place, the dam continues to function efficiently in reducing flood risks for the surrounding community.
As water resource and climate enthusiasts, the data on Norman Twp 7 provides valuable insights into the infrastructure and management of dams in Minnesota. Understanding the importance of maintaining and improving these structures is crucial for ensuring the safety and resilience of communities in the face of changing weather patterns and increasing flood risks. Monitoring the condition and emergency preparedness of dams like Norman Twp 7 is essential for sustainable water resource management and climate adaptation efforts in the region.

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.
