Here is a pic of a tire structure I made a couple of weeks ago. It's about 25 feet from my dock and you can still see the tire on the bottom that's how clear my pond is. I put one big tractor tire on the bottom and then put 2 in the middle so they can swim through the tires and then put 1 on each side of the large tractor tire just leaning up against it. I used rock to keep it all in place inside the tires. This is in about 4 feet of water.

The only difference between a rut and a Grave is the depth. So get up get out of that rut and get moving!! Time to work!!
