My pond project has officially started and I'm looking to sink a whole line of trees down the center of the lake (approximately 12-15' of water). I have access to a lot of scrap 2x4 and other lumber, so my thought was to submerge the trees in a triangle pattern and then nail the 2x4 material between the trees to create smaller gaps for the baitfish to hide in. My logic here is that it will last a heck of a lot longer than the thinner branches and make it much easier to work with. Obviously, I'll leave a few branches on the trees but was planning on thinning them out quite a bit because I have no idea how to erect these things if they have a full canopy on them.
My property has mostly hackberry, elm trees and willows. I do have a few live oak and mesquites, but we were trying to save as many of the Live oak as possible and there's probably only about 6 mesquites that are large enough to do anything with. There are also a lot of properties nearby that are typically looking to get rid of cedar trees. I'm wondering which tree will last the longest or be the best to submerge for cover. I'll likely be targeting trees with a diameter of at least 6".
Thanks in advance
