Today Brian came down from Indianapolis to help me work on the new ponds. This series of pictures requires more than usual explanation.
In the first, behind me, one can see the south side of the larger pond. If you click on either of the first two and look very carefully, you might be able to make out the thin yellow string along the top of the dam. Though it may not appear so, the string is level. Eventually the top of the dam will be leveled and parallel with but not all the way up to the string.
Notice the water that is still in the bottom of the pond. It might not be necessary to line these ponds since there is so much clay and it seems to be holding.
In the first two pictures we are working on a spillway of sorts that will allow rain water to flow into the bottom pond if it comes off the small hill to the left or off of the east end of the trail that passes above them.
The shiny soil under my feet is a finished stretch of the spillway. If the lower pond gets near to full this area will be under water.
Brian is touching a large rock somewhat smaller than a few we moved on the south side of the spillway. I am tromping on the outside of the upper dam which is also the north side of the lower pond. Next to the rock, though expertly hidden by the crew, a corrugated pipe has been buried to allow water that flows over or along the trail to enter without eroding the upper dam's lower wall. The clay is not as mucky as it was just two days ago so it did not stick to the shovels much. With two of us working it was easy to raise the dam walls, one placing shovels full of clay while the other pushed and stomped it into place before it could roll down the embankment. Before, with one person working and the soil sticking to the shovel, placing it successfully on top of the dam was nearly impossible.
This last picture shows a wider view of the two ponds. From the top one can see the edge of the trail along the north side, a small trough filled with rocks to encourage drainage from above the trail to enter the upper pond, a line of larger rocks delineating the west side of the pond, the upper pond itself, the overflow pipe into the lower pond covered with a large rock that was placed by the backhoe, and the outline of the lower pond with the crew in it.
I have a pretty complete idea about how to finish off the ponds' walls, inlets and overflows. Early in the spring I'll seed the outside dam walls. After seeing these pictures, though, just one thing still puzzles me: Where the hell has all my hair gone!?
