Hey I live an hour east of rat we do a lot of open water fishing there in the summer the lake is known for crappie and beings its a river there is a lot of current so the main body is a gamble at best I know a lot of guys fish the creeks that feed in and some of the big bays on the south side are good but I'm tellin ya be careful specially early and late when the fishing awesome take a friend and a rope we fished it late one year and caught all 4 limits quick nice big crappie went back the next day and couldn't get to our shelf because the ice turned over night we watched a quad go in and even an Irish setter named Jessie ( I know the name because then guy was screaming at the dog for 10 mins) everyone got out. That's the only place I went swimming we were on 6" of good ice and I took off for the other tent our friends were in and next thing I know I was in up to my chin. I was 40 feet from the tent and luckily they heard it and was out quick but we caught some nice fish
