I spent the morning cleaning out the big pond. Lots of dirt and gunk and water had accumulated in the bottom over the past months. A combination of the little sump pump and a shop vac cleaned that all out.
But more concerning was the fact that when I walked down into the pond, it was mushy. There was obviously water underneath the liner.
I just pulled back the liner to reveal the water that had gotten under. It is likely that this water is from the overflow when I was testing the filter. It could be from a little bit of rainfall, but I doubt it.
There was a lot of water washing around the yard yesterday as I was figuring out the filter and the stream and overflowing areas so I am sure it got in that way.
Not a big problem. Just some more water to move with the little pump.
I am more concerned about the fact that a horsefly landed on me twice in the past hour. Devils they are.

alright. emptied the pump bay (watering the hazelnut tree as I go) so I could get down into the box and loosely fit the hose onto the pump.
Now we'll turn the water back on in the filter and let the bay fill back up again from the little diversion stream.
I need to go get a couple big hoseclamps to properly secure it to the pump. But loose is fine for testing.

Ultrashort Time-Integrated Diagnosis of Laser-Heated Deuterium Ions in Dense Plasma via Fusion Neutron Spectra
The ultrashort time-integrated diagnosis of ions plays a vital role in high energy density physics research. However, it is extremely challenging to measure in experiment. Here, we demonstrate a reliable approach for investigating the dynamics of deuterium ions in dense plasma. By irradiating a heavy water stream with the hundred Hertz repetitive intense femtosecond laser pulses, the neutrons from D(D,n)3He reaction can be detected via a single Time-of-Flight detector to accumulate the spectrum…

This is the #Garbce stop on railway line 271 (Poznań — Wrocław), renovated a few years ago.
The platforms end a dozen metres from the railway crossing. However, there is no walkway from the platforms to the crossing; probably because it would need to cross a tiny stream. Instead, a 100 m long walkways have been added to the other end of the platforms, with a tunnel joining the platforms and access to a side road in the town. To reach the railway crossing, you have to walk 700 m.
Ironically, even in the general drought the tunnel manages to feature puddles of ground water. Also including the photo of a platform roofing with weird orange marks.

Remember to stay hydrated, my peeps

Now that we have had our brief bit of fun with the #poolpond, it’s time to drain it so work on completing it can continue! It took just over 12 hours for my little spare pond pump to empty the main pond of about 80% of its water.
It will be empty by morning. I will empty the filter and intake bay as well just to clean everything out. The movement of the past couple weeks through the system will have loosened up a bunch of the gunk still on the various rocks in the filter so a full pump out should remove all that.
I will then concentrate on finishing the piping in the bottom of the main pond for the intake for the second pond and the “periscope” for the bottom returns.
Then I can work on building the rock wall to line the inside of the pond. Or at least experimenting to see if it will work at all!
If it *does* work and I have enough rock to at least start on the bottom layers of the inside wall, then I’ll be able to achieve another milestone: placing the final pebble on the bottom. Important, because that will prevent any groundwater from infiltrating and causing the rubber liner to bubble out.
Really really want to get past that mark before the autumn rains come! For obvious reasons! ☔️
Other jobs that need to be done before winter:
- finish the manifold for the second pump to distribute water to the sprayers and filter and figure out how and where to house and conceal it.
- Dig the electrical trench from the house all the way around the long side of the pond to the back tool shed so we can start wiring it in.
- Clipping the wires on the pumps and adding extension wire to them so they can reach said electrical supplies.
- permanently shore up/modify the borders of the ponds where they were found to be low.
- make a few other minor terraforming modifications for the stream and some of the edges so the water goes a little more where I want it to and a little less where I don’t.

today i cycled along a dried up stream. found a couple pools of water remaining. loadsa white butterflies drinking from the bank. and a gret fat dragonfly that kept fucking off every time i pointed my camera at it. i was there for ages but could not get a shot. i could just imagine - "NO PICTURES you scrawny ol' bastard, fuck off" so i rode around for a hour or so, came back and finally got this shot. ha ha

The first trickle from filter to pool pond.
The main pond is not quite 3/4 full, but I thought it was important to make sure the filter was completely full and ready to start filtering. So I have shored up the low edges of the filter, taken away the temporary stream, and now the water is starting to flow from filter to pond. In time it will connect with the pump bay. Then I can turn on the pump and start circulating for real.
😆
The reason this is happening now is not the best reason. Our view to the southeast is not encouraging.

A #pandemicpond post.
The bog-barrels that I added last summer have done an absolutely incredible job at keeping the water crystal clear and almost completely algae free this summer.
Only the much warmer stream between the ponds has more algae than I really like.
I also added the bigger pump at the same time which likely helped a little but the added flow also raised the level of the top pond just above the liner in some spots. So yesterday when I topped it up, I took away the flat border stones to inspect where it was leaking. It turns out, almost everywhere!
So I added some handfuls of pebble taken from the #poolpond filter since I know there is extra there..: and stuck it under the liner to raise it an inch or two all the way around.
Here is a before and after. The first pic with the purple lilly
pads is last year with the algae that was common in the summer before the big filters. The second pic is a few weeks ago when the pond was full, clear, but overflowing, notice the water overtop the flat stones. The last two pics are today after raising the liner a little under the stones.
And a pic of the happy dual-barrel bogs (which are just small versions of the giant filter I just finished in the backyard). The marsh marigolds have not bloomed in the bog barrels. Not sure if they will this year. It is quite shady for them.
Oh and a lilly is about to bloom!The fish are also very active and happy.

It is so nice how the #pandemicpond is maturing now. This is its 5th summer! Can't believe it. The bog filter has made a massive difference for the water clarity and keeping down the algae. The first pic below is from this time last year and you can see the algae clouding and sliming everything.
Two years ago I started planting some moss around rocks in the stream and it has filled in really nicely and naturally. It also served to trap seeds I think and grass and other "weeds" but I like that it just looks more and more like a normal stream. We even have a marsh marigold at the top of the stream (last pic) that we did not plant that came from one that was in the top pond and was eaten by deer. 🦌
