Summer fishing has remained good as water temperatures are continuing to rise with the warm weather. This time of year, look to be on the water early and off before the lightning and storms roll through the area. Grand LakeBoat ramp hours are 6 a.m. to 8 p.m. Water temperatures are in the mid to upper 60’s. Lake trout action has been fair. Brown trout action is good when the afternoon storms roll in or on the overcast days.
