They are starting to pull piers so if you are planning on using the public boat launches in N. Wisconsin it is a good idea to wear some knee boots. I think they pull the ones that seem to freeze first. The launches that are in shallow and protected from the wind that is. Water temps rose from 55-57 from last weekend. One deep clear lake was close to 58 when I got off at 11. Minnows were thick along shallow coontail but not much biting for me.
