Our new pond (part 4)

I worked the two full days in order to add height to the dam. The most tiring part was associated with the stress of driving my truck, my tractor, and a backhoe on top of the dam. I especially don't like when the backhoe leans to the side and when I got it into some of the soft topsoil on the back slope. I decided I didn't need it up there.

The method that seemed to work well for me was to load clay into my truck from a couple different places in the floor of the pond. Then, I drove this onto the dam and dumped it where I wanted it, spreading it out some as I dumped. After several loads, I switched to the tractor and blade to move the material where I wanted it and to pack it some more (the truck tires were doing a pretty good job of packing).

After getting enough clay built up, I took a few loads of top soil to put on top and spread that around. It went fairly well.

This photo shows the outcome of my efforts. I added enough material to put the top of the dam two feet above the primary spillway (the 12" culvert). This also allowed more freeboard above the emergency spillway, which is a good thing.

A little closer look. The section I built up looks darker because of the topsoil I added.
Digging clay and soil out of the pond bottom helped to add some more structure for fish. Structure is basically variation in depth, especially differences within a short distance There is a fair bit of variation on the bottom.

This is a view looking toward the dock from the dam. I was trying to show how the dock is on a ridge with drop offs on either side. There's also another elevation change going into the shallow end of the pond which is a result of digging out clay and top soil to raise the dam.

Looking a little to the left toward the shallow end. One of the things I wanted to do but haven’t done yet is to make a small beach area toward the house where I drove in and out of the pond hauling material.

This photo looks past the pond from below the dam toward some of my fields. Shortly after finishing the dam height project, I seeded the dam with fescue. At this point, I needed to finish the dock framework and then wait for rain to fill up the pond.
