We're spending the next few days dredging the pond. It's a job I hate, but needs must. I've decided I need to make some major changes, because I do NOT want to be doing this every three or four years, which is what it seems to require. It's not very big, and a hard-shell with shelves.
The pond baskets with soil in them are going. Even if I line them, the liners rot over time and the dirt leaches out. There must be a good four inches of silt in the bottom of the pond, and the frogs kept it constantly churned up this year. The apple tree leaning over the pond didn't help, (it was either shedding petals, apples, or leaves straight into the water, depending upon the season.) It fell over back in the spring and has been propped up ever since... I wanted to give it one last season to flower and fruit, but it was dying... it was cut down today.
I was too enthusiastic with pond plants, (novice mistake!) and at one point I had at least seven different kinds in there. They were always competing for space, and they make it really difficult to sieve out the duckweed. From now on, it's hornwort and water cress. I can simply toss a bagful of cress from the supermarket into the (empty) pond baskets and it flourishes. Then I can simply lift it out when it gets overgrown. I love the Mare's tail, but every time it rained it flopped over and just made a mess. It needs a MUCH bigger pond, (as does the fringed water lily.)
The poor frogs are not happy with me... they're sitting on the emerging shelves looking very peevish, but I'm sure they'll be happier once it's done and they've got room to actually move about. I'm going to sink some pond baskets full of rocks and hornwort for them to hybernate in, and maybe a few submerged shelters made from a couple of broken paving slabs.
We've syphoned out most of the water today, but tomorrow the real fun starts... hauling out buckets full of muck. Not looking forward to it, but I shall post photos of a lovely clean pond in a couple of days, (provided I don't fall in head-first and dislocate something!) I've got to try and catch the infant newts, too... that should be interesting.

Know what you mean RB. Our pond suffers from inappropriate plants - the lily is far too large for the pond and I can't keep the fallen tree leaves out.
The good thing about lots of vegetation is that it takes the nutrient out of the water which seems to reduce the blanket weed. If I can delve through the water soldiers, water mint, lily leaves, duckweed and the brooklime, the water is really clear.
The frogs will survive, they are tough characters but you might find the most difficult thing is stopping them hopping back in while you are working on the pond.
I found the easiest way to get the sludge out, some of which was kept to go in the new pond, was to get in the pond and work from there. It also made catching the last few frogs a little easier.
Good luck
Dave

I have a small pond. I scoop the mud out of the bottom using a net on a pole, like the sort you can get at the beach

I tried doing that, Teasel... it just stirred it up something awful!
It's done now. We did siphon out most of it, but the rest had to be done the hard way... and it's about 2 feet (62cm) deep
I can't lift my arms above shoulder-height now- after hauling out buckets and buckets of smelly, slippery mud and gravel and vegetation, the only thing I want to do now is take several extra-strength Ibuprofen and collapse on the settee in front of the telly. Still, it looks great. If we get another heatwave next Summer, I might be tempted to toss the frogs out and use it myself.
A frog ladder is in one corner, although they can also get in and out via the cascade, (the lower bit of it is submerged when the pond is filled.)
I must have fished out around two dozen frogs, (and yes, they did keep trying to come back!) around a dozen newt-poles and nearly as many dragonfly nymphs. (I never even saw a dragonfly around the pond all summer.) The newts and nymphs are in containers, and will spend a few days in the shed until the pond is refilled and the chlorine evaporates. It would be nice to let it fill with rainwater, but that would probably take until Christmas!
I saved a huge bucketful of hornwort which will go back in tomorrow, and come Spring watercress will go in the two pond baskets which the cascade is resting on.
The bricks under the baskets also provide hiding places for the frogs- and they are able to lurk under the cascade, too. I've put a bit of wire garden fencing across the top bit of the cascade... I discovered this to be a necessity after looking out one morning to see the vixen perched on the end of it like it was a diving board.
At first I thought she'd acquired the talent of being able to walk on water! She does love frog-hunting.
