When do you think you will be making the trip up? lots of lakes that hold eyes in NE South Dakota, if you get up here I would say check the local bait shops to find out where the bite is at. Towns to stay at Webster or Watertown Would put you close to a lot of lakes. As far as conditions though not many getting out on the lakes unless you have a sled or a atv with tracks. There is a ton of snow on the lakes, bring your shovel to dig the truck out when you get stuck.
