by Minnesota DNR,
Anglers for the first time will be able to fish for trout in the winter on two dozen north-central Minnesota lakes, many of them within the Cuyuna Country State Recreation Area.
Trout fishing on these lakes, which contain stream trout, will be open from Saturday, Jan. 17, through Tuesday, March 31. Stream trout are rainbow, brook and brown trout, and a hybrid of lake trout and brook trout called splake.
