When will the ice go out??

I see everyone has cabin fever and heading to the Rainy River to do some walleye fishing. We just got home yesterday afternoon and we were surprised to see some open water on Caliper Lake and just a small amount of snow left. It always amazes me how I was driving on Whitefish Bay on April 3rd. I really think we will see some open water before May 5th. When do you think the ice will go out? Weather this next week will be in the 60’s F all week that is 15.56 C.
