Yeah, most anything worth fishing this time of year is about an hour to an hour and a half away from Bismarck. There are fish in Sweet Briar, but it's often a tough bite in the winter. Maybe New John's, but it too can be a tough bite through the ice (at least it has been for me).
Harmon can be good for bluegills or crappie. Not usually big. Occasional pike there too.
New Johns and Sweetbriar at sundown for the elusive walleye. Fish Creek for trout can be fun.
