Hamilton is an easy lake to find brush piles in. If you have a decent fish finder you can just idle in front of docks. Look for those with rods, rod holders, or fishing chairs on them. That is usually a dead giveaway that brush is nearby. When you find the brush you should find the crappie. Just slow roll a 2" grub over the brush and have fun. I grew up fishing that lake and I've spent many a day out there. I don't fish it much anymore cause I live about 10 minutes from Crystal Springs boat ramp on Lake Ouachita. Hamilton is not a bad lake for fishing but this time of year the weekends get too busy for me with all the pleasure boaters.
