Summary
Owned by the local government and designed by BOULTON MENK, this earth dam stands at 23 feet high and was completed in 2006. With a storage capacity of 100 acre-feet and serving a drainage area of 6 square miles, this dam plays a crucial role in protecting the surrounding area from potential flooding events.
Managed by the Minnesota Department of Natural Resources, Florida Twp 9 is subject to regular state inspection, enforcement, and permitting to ensure its structural integrity and functionality. Classified as having a significant hazard potential, this dam has been assessed to be in satisfactory condition as of November 2012. Despite its notable risk level, the dam's emergency action plan status and risk management measures remain unspecified, suggesting a potential area for improvement in emergency preparedness and response.
In the event of an emergency, it is essential for stakeholders to stay updated on the condition of Florida Twp 9 and be aware of the designated emergency contacts. With Collin Peterson (D) as the representative for the area, collaboration between local and state agencies is crucial for effective risk mitigation and management strategies. As climate change continues to impact water resources and weather patterns, the importance of maintaining and enhancing infrastructure like Florida Twp 9 becomes increasingly significant in safeguarding communities and ecosystems from potential flooding risks.

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.
