The Minnesota Department of Natural Resources will hold a virtual public meeting at 7 p.m. on Tuesday,
Nov. 17, to discuss a request from the Round Lake Association to use winter aeration on Round Lake,
located in Meeker County south of Litchfield. The meeting had been scheduled for Nov. 2, but was
postponed because of technical issues.
The meeting will start with a short presentation on the effectiveness of winter aeration in public waters,
and will include an opportunity for public comments and questions.
Written comments will be accepted through Nov. 24 by emailing hutchinson.fisheries@state.mn.us. The
DNR wants to hear from a variety of audiences and plans to incorporate multiple perspectives in its
decision-making. 
Lake aeration in the state’s southern region is used on several shallow lakes to prevent a winterkill of
fish. Aeration systems agitate and oxygenate water, helping to limit the number of fish that die due to a
lack of oxygen in the water. Aeration results can vary widely.
Winterkill is a natural process and not all results are detrimental. For example, in lakes with high
numbers of carp, periodic winterkill can thin out their numbers. In lakes that support gamefish, the fish
population can rebound quite dramatically in years following winterkill.
People interested in attending the virtual meeting, should visit the Round Lake link at
mndnr.gov/areas/fisheries/hutchinson.
Preregistration is required, and attendees will be able to join starting shortly before the meeting. 
Individuals with a disability who need a reasonable accommodation to participate in this event should
contact Liz Scherber at 651-259-5223, elizabeth.scherber@state.mn.us or through a preferred
Telecommunications Relay Provider as soon as possible.
