Pond Installed!!

Well, the pond itself is installed! A lot of things came together last weekend (1/11-1/13): the underlay/liner was delivered, rocks were delivered the previous Wednesday, and I found a guy who could get me a load of gravel to suit that day. So, Friday, after everything arrived, I figured I had all the ingredients, so I might as well cook!
Rocks (rounded river, large flat) and gravel for pond

After putting in the underlay, Liz helped me stretch out the liner and stuff it into all the cracks. I think we probably could have done a better job of smoothing out all the wrinkles, but given that this was our first real attempt at this, I think we did OK. Also complicating the installation was the fact that the water table was up above the bottom of the pond, so the pond bottom at its deepest part was actually more like quicksand. Once rocks were put in, the bottom sort of bulged out, but I figure it won't make too much of a difference once the water is in and pushing down on everything.
Liner in place (EPDM, Firestone Pond Guard, fish safe)

Rounded river rocks in place to hold in/hide liner

After some work getting everything into the skimmer and running the plug through some makeshift conduit to the outlet, I covered everything up and put out the big flat rock on the top level of the pond. It was at this point that I realized that we vastly UNDER estimated our need for rock. We ended up using 2 tons of rocks just for inside the pond and the pond lip. We easily need another ton around the top outside, and then at least a ton for the water. It's a bummer, as we'll have to pay for shipping twice. The lesson here is BUY MORE ROCK THAN YOU THINK YOU COULD CONCEIVABLY USE!! We actually did that, but since we had nothing to compare it to, we did a poor job of estimating.

After the rocks were up, I cut away the excess liner. By the way, it looks like we ordered way too big of a liner, but as it turns out, you can only order it in multiples of 5. We ordered 25' X 25'. But after cutting around the pond, there were many sections that we less than 5' wide, so we did not over order. It's definitely better to over order than to not have enough to go all the way up.

After some rain and snow this weekend, the pond is filling up nicely! I resolved to not use any groundwater to fill it, given North Carolina's drought situation, so I hooked up one end of a hose to our overflow for our rain barrel, so the pond gets filled with rainwater/melt-water from half the roof of our house.

Unfortunately, I must have put a little too much on my back, and it gave out unexpectedly last week without notice. As soon as it gets better, I have to set up the grow bed/bog and waterfall, as the pond will soon be full enough to begin running the pump.
