Summary

These buttress dams on Meadow Creek-TR serve the purpose of roadway retention and are regulated by the Minnesota Department of Natural Resources. With a dam height of 22 feet and a storage capacity of 210 acre-feet, these dams play a crucial role in flood control and water storage in the region.

Although Sodus 21 & 28 have a low hazard potential, their condition assessment is currently not rated. The last inspection in April 2019 revealed no major issues, but their inspection frequency is set at every 8 years. As part of the emergency preparedness plan, it is important for the local authorities to regularly update their contact information and ensure that the dams meet safety guidelines to mitigate any potential risks associated with these structures.

Overall, Sodus 21 & 28 are essential components of the local water resource infrastructure in Minnesota. With proper monitoring, maintenance, and adherence to regulatory standards, these dams continue to serve their purpose effectively in managing water flow and protecting the surrounding areas from flooding. For water resource and climate enthusiasts, understanding the role and condition of these dams is crucial in ensuring sustainable water management practices in the region.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
