The "Early June" fishing conditions happen when the surface water temperatures are between 55 and 65 degrees. The little green algae is blooming there, the phytoplankton critters are feasting there, the newly hatched fry and minnows are there and all the yellow perch, white bass, white perch, walleyes are up there feeding. So keep your lures above 20 feet using sideplaners with 3 colors of leadcore, jets and dipseys about 50 to 75 foot out depending on the side settings.
