We were fishing yesterday on the big lake not doing so well, actually not well at all.  ( But still having fun!!) Called some guys on a 2-way and asked them how they were doing and how deep.  They did well at 18 to 22 feet, so we headed deeper and caught around 25 nice walleyes.  If I was to tell you how to fish that lake this time of year with out a doubt I would say shallow and in the weeds, this year so far anyway is not the case.  We went out deep from where the fish should have been and caught a few as deep as 32 ft.  Sometimes we need to change and try different things, I'm not one to usaully do that, but this year with the water cool I guess we need to adapt.  If you can find a few fish and stay on that break line, deep water fishing can be alot of fun.  Boat controll becomes pretty important here and having confidence helps alot also.  I don't believe you catch too many fish on acident, if there is one there probally are more.  Get lucky, catch a fish or two and stay in that dept and see what happens.  Oh by the way, My father kicked my butt fishing yesterday, many over 20 inches.
