I limb line every summer in the river south of my house. I use willow limbs cut to about 8' in length. I also use 1" PVC pipe the same length. I push these poles into the river bed to where the bait will stay into the deep holes I find in the river. I will lose a pole every now and then but I usually find it tangled up in the brush a week or so later . Keep your bait off the bottom and use enough weight so the bait won't be carried to the top by the current.
