More about dredging

Steve and I climbed to the top of the berm around the pit where the silt from the lake bottom is being deposited via an 8-inch diameter hose/pipe. You can see some of the water already in the bottom of the pit. Notice the small mounds of dirt. They are required "islands" to provide a nesting place for birds, once this becomes a permanent wetlands.

According to Steve, the depository pit was originally dug 30 feet deep. This was not in accordance with the agreed upon plan, so the company had to come back and fill it in to a depth of about 10 feet with an overflow drain at 8 feet. The bird islands were apparently added at that time.

Looking down from the the 6-foot wide berm around the depository pit in the field across the road from the nature preserve next to our property.

You can see the berm on the right and some of the water piped across the road from the lake.

A better view of the berm. The road is to the right and the lake beyond that to the right.

Pipes from across the road to the pit.

We talked with one of the crew members, who told us the pit is about 7 acres and they will dredge 5 acres of the lake in our area. He thought the pit would be filled to a depth of less than eight feet when dredging was completed here.
