Fireline,
The area around Watertown is fantastic. One lake that I personally love is Lake Poinsett. It’s about 20 mins south of Watertown. In the spring it’s not that uncommon to catch multiple picture fish at a couple creeks that flow into the lake. There are a ton of lakes that hold walleyes really close to Watertown. When the time gets closer, shoot me a private and I’ll call some buddies back there and get you a report.
