Summary
The lake primarily serves as a local government-owned water resource for the residents of Arlington with a surface area of 307 acres and a drainage area of 2.74 square miles. The dam is regulated by the Minnesota Department of Natural Resources and is inspected regularly to ensure its fair condition and low hazard potential.
Located along Judicial Ditch 22, Round Grove Lake plays a crucial role in water management and conservation efforts in the region. With a normal storage capacity of 1595 acre-feet, the lake helps mitigate flood risks and provides recreational opportunities for the community. Despite being a small water body, Round Grove Lake contributes to the overall ecosystem health and acts as a vital resource for climate enthusiasts interested in sustainable water management practices.
As a historic dam with a rich legacy dating back to the early 20th century, Round Grove Lake showcases the importance of maintaining and regulating water resources for future generations. With its fair condition and low hazard potential, the lake stands as a testament to responsible water infrastructure management in McLeod County. For water resource and climate enthusiasts, Round Grove Lake serves as a valuable example of how local governments can effectively steward vital water sources for both practical and environmental purposes.

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.
