Tonight's update:
I've taken a break from pond building to play tour-guide for a distant cousin who's visiting from the U.S. (Didn't even know I had a cousin until she contacted me some years back!) But a few things have happened pond-wise:
On Friday I pumped all the filthy water from the initial fill into the garden (was quite a chore, let me tell you!) then refilled with the final (?) fill. I'm still not finished with the edging, nor do I have all the gravel in, so I expect the pond to remain murky for some time as I continue to work. However, having the pond full has been extremely helpful. For one thing, I can see exactly where the edges are--or should be! Not having a laser transit, figuring out the final water level has been something of a guessing game. My little Ikea picture-hanging laser was good enough to give me a very rough estimate (providing I used it at night, when I could see the laser line across the pond). But now that I've got the exact levels, I can dig out a bit or backfill a bit to get everything just right.
What's more, I'm finding that moving those heavy rocks around underwater is ever so much easier! Limestone is only about 2.5 times the density of water, so they aren't nearly as heavy once I get them into the pond. This has made the work of rocking in the upper edges that much easier. I've still got a long way to go, but I can already get an idea of the final composition.
Also on Friday, I foamed in the waterfall spill stone. I wasn't able to get everything around it foamed in, as I ran out of time, but at least I've got most of the water going over the spillway now! Looks and sounds great! I've left it running for a couple of days in order to check levels and see where else needs to be foamed. Because I can't get waterfall foam here, I'm using construction polyurethane foam. Seems to do the job.
Here are a few pics:
The pond lit up by a little solar powered spotlight in the intake bay. This view is of the waterfall from the sitting area.
The foreground will eventually be covered by landscape fabric topped by pea gravel. I've got a few nice flat stones to put along the pond edge, cantilevered over the edge a bit.
Today I managed to clean off and maneuver a huge (and heavy!) old olive branch into place to form part of the wall on the western side of the pond. This view is looking over the branch back toward the sitting area and intake bay. I love the way the sunlit waves cast light across the rocks and plants!
Here's another pic of the same view:
I'll need to raise my "turtle rock" up by about 15 cm, so that at least half of it is out of the water.
No major leaks at least, as I haven't seen any drop in water level in the past few days, despite a major heatwave over Shabbat. So far, so good!
