This is a shot of where the biofalls used to be, right in front of the three little Juniper evergreens. Monday, September 19, 2005, 10:08 AM

I had to enlarge the hole where the Biofalls was so that it would be big enough to accept the 'centipede' and 'snorkle'. It wound up about 8 1/2' long, about 4 1/2' wide and about 3' deep.
)
After we unhooked the 2" hose, we just laid it in the stream and kept the pump pumping water so that the water would continue to circulate and provide the fish with pleanty of oxygen and also so the marginals in the stream would stay watered and survive.
)
This is just another shot of the corner of the yard where I was working. To the left of the Junipers in the corner, you can see the 'snorkel' laying on it's side. The 'cenetepede' is behind the Junipers.
)
Once the dimensions of the hole were adequtae, I dug a trench where the centipede would lay. The deeper part of that trench is where the snorkle will sit.
)
We added about 1 1/2 tons of limestone boulders to the landscaping to be able to raise and enlarge the area where I was digging the hole to make it long enough for the centipede and snorkle to fit. That's the bottom of the 'snorkel' laying against the fence on the left side of the picture.

This shows the hole with the 45 mil EPDM pond liner in place. The centipede is the black piece laying in the bottom. The far end is where the new 3" water hose will attach. The centipede has a series of slots that allow the water to fill up the bog. The upright piece with the grey lid is the snorkle. Every 3-5 years, I'll need to unscrew the top off the snorkle, and use my spare pump to pump the goo out of the bog. 'Goo' is a technical term for dirt, decomposing organic materials and fish waste.
