Summary
is a local government-owned structure located in Lyon, Minnesota, specifically in the city of Tracy. Situated along the Lone Tree Creek-TR, this dam serves as a crucial water resource management system with a dam height of 21 feet and a storage capacity of 107 acre-feet. The dam, constructed with a buttress core type, spans 540 feet in length and has been regulated by the Minnesota Department of Natural Resources' Environmental and Water Resources division.
Despite being rated as having low hazard potential, Monroe 13 & Redwood Co. has not been formally assessed for its condition. The last inspection was conducted in April 2019, with a scheduled inspection frequency of every 8 years. While the dam has not been modified extensively since its completion, the lack of a condition assessment raises questions about its long-term viability and maintenance needs. Additionally, emergency action plans and risk management measures are currently not in place, leaving room for improvement in ensuring the safety and effectiveness of this water infrastructure.
For water resource and climate enthusiasts, Monroe 13 & Redwood Co. presents an intriguing case study in the management of local dams within Minnesota. With its location in a rural area and reliance on Lone Tree Creek-TR for water supply, understanding the regulatory framework and operational challenges faced by this dam can shed light on the broader issues of water resource management in the region. As discussions around climate change and extreme weather events continue to escalate, ensuring the resilience of structures like Monroe 13 & Redwood Co. becomes increasingly important for sustainable water management practices in the future.

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.
