Winter Cover: Attempt number 2
I've decided to try a pond cover this year. There are two reasons for this. First, it is an attempt to make winter less stressful for my fishy friends. Second, to keep all of the winter blown leaves, seeds, sticks etc and you never image you be a factor in the winter, until you get a pond.
My first attempt at a pond cover was a big Ole fail. I criss crossed multiple 2x6 beams across the pond in sort of a spider web pattern and then caulked different sections of plastic to each area. I can't remember why I didn't cover it with just a single giant sheet. That might have held up a little longer but in the end would have failed for the same reason this did. Water is really heavy. Rain drops water on plastic, which stretches it forming deeper and heavier pools until the caulk gives and the cover fails.
Attempt number two was full of adventure. I decided to make a sort of tunnel over the pond, out of bent PVC. I didn't build it over the pond though. I build it on the driveway. Picture a sort of skeleton of PVC that is 26 feet long and 20 feet wide. Now picture a lone person moving said structure down the driveway, through the yard, between trees that are 15 feet apart and over a fence. It was, er interesting. Almost as interesting as getting each side of it on opposite sides of the pond. (Eventually completed by just dumping one end in the water and fishing it out.
Raising the structure was easy, as was getting the plastic over the top. It looked most excellent until the first big windstorm (40mph gusts) when it tried to blow away. I eventually made it heavier with an additional top of 6mm plastic and disassembled half of the circle garden blocks to weight it down. It has held up to recent winds OK. Snow will likely destroy it but at least it is buying me a bit of time. The inside of the tunnels is like a rain forest. Condensation coats the sides. I moved my wheel planter in there and planted some beets and lettuce to see if I can get a winter harvest out of the project. That's if winter ever gets here. Today was 64 degrees.
