When locating perch in a body of water, look for areas with structure such as weed beds, drop-offs, or submerged trees. Perch like to hide in these areas and wait for prey to come by. Pay attention to the water temperature as perch prefer cooler water. Also, look for areas with a lot of baitfish as perch will follow them. If you're having trouble finding perch, try moving around to different spots until you find where they are congregating.
